What's your MPG?

[Steve]

I did a test over the last tank of gas, mind you it's been raining so I expected to get at least 10% less fuel mileage because of tire slippage.

My 99 Cavalier got 25.6 MPG over the last 268 miles. Not quite as good as it has been, but as I said it's been raining and I've been driving it more for short trips lately because it gets better mileage than the Trailblazer.

[garretthes]

My Chrysler T & C was getting 20 mpg 50/50 highway city.
My 59 Suburban gets around 13. That's with the old 235 straight 6.

I think you may be over compensating for tire slippage at 10% IMO. You should only get that kind of slippage if your really getting into it, even in the rain. Or if your tires need replacing.

Well, I thought so too, but a local car guy on the radio (Ed Wallace) said on his show a couple weeks ago that the average is about 10-15% worse mileage when it's raining. I guess it's because of an overall lower co-efficient of friction.

[Chevy Girl]

i guess i get about 16-17 mpg in my trailblazer. There are quite a lot of hills around here and talk about tires slipping from rain! We invented rain!

[nanomex193]

I have an 06 chevy colorado crew cab 4x4 and the estimated mpg are 28 highway and i drive about 50/50 highway to city and i get about 28 to 30 miles per gallon now but in the winter i got 24.5mpg

[GeoK]

I have been tracking my 2003 Suburban for a couple years separate from what the onboard trip odometer says. I average just under 15 mpg. There is rarely any major fluxuation in the mileage.

[maxumpower]

My 1997 sonoma gets over 32 MPG! I installed an electric fan, under drive pullys, and a cold air intake on the 4 cylinder 5 speed engine. Even with all that stuff to help the engine i would still lose a 0 to 60 mph race against an old lady in a walker!!! :rofl:

[rwhitbeck]

I have not had the opportunity to check mine yet as I am still trying to get it through emmisions (just have not had money yet). Once I actually have it registered and on the road, I will be verifying the mileage...even when gas was cheap in the 80's as a teenager I checked mileage (my girlfriend lived 120 miles away from me)...it has always just made sense to do so. I always figure that if you know what mileage you are getting when you start with a new vehicle, you can build on that number or at the very least maintain it!

[kwwood1]

I have a 93 K1500 with about 5K miles on a rebuilt 350 and tranny. I have been getting about 12.5 around town...haven't gone on a long enough road trip lately to get highway mileage.

I would much rather have the 32 MPG than win a race...can you haul a trailer...that would be my only issue.

[singleshot54]

I've been tracking my mileage since I bought my truck, it is a 2003 Silverado, 2500 HD 4x4 with the 6.0 L engine. I've got 57K miles and I get an average of 15.3 MPG, this includes city, highway, and towing my ATVs.

All I've done is add KnN air system and a cat back exhaust (Flowmaster). Any ideas on what else can be done would be appreciated!

Hey, Jack...I'm not super familiar with that vehicle, but if it uses a throttle body injection, I have heard some people say that a spacer has helped their mileage.

On a side note, I see that you were Army...me too! I did not do as many years as you probably did (only 5), but they were by far some of the proudest years of my life! Nice to meet you!

[Westxsrt10]

1500 miles on the tahoe so far..easy driving too 15MPG not great for a 5.3

[Raydar]

With My Sonoma (4.3, 4L60, 3.42 FDR; aka the Pewter Pig) I get about 18-19 mpg in my typical routine. Long trips (~75-80 MPH, all interstate) will get me 22-23.

[97Tahoe]

I also have been checking my mileage since I've been driving (mid 70's).
97 Tahoe 16 mpg
97 Grand Am 4 Banger 31 mpg
02 Sonoma 20 mpg
07 Impala 25 mpg
My 04 Impala got 30 mpg looks like I should have kept that one.

[Cableguy]

I'm still around 16/17 I don't drive it much. So its not a huge concern for me. I certainly do feel for those of us on here that commute to work though. There has got to be a way to straighten out Big oil companys beside devine intervention! Has gas ever fluctuated this ridiculously in the past. I can't seem to ever remember it being this unstable...

[maxumpower]

It can pull small trailers all day. It towed a double axle car trailer (empty) on a three and a half hour drive to pick up the 1991 blazer. I knew it wouldn't tow the blazer so it got to ride on the trailer back home.

[sfowler]

I had to get rid of my Trailblazer the cost of keeping it running was getting to much. I did go out and buy a new Tundra and I'm getting 20 to 21 mpg with it very happy with the new truck.

[dbledsoe]

My 94 K1500 Suburban gets about 15, and has been pretty steady since new. Now has 229,000 miles.

[mont91]

The 2 vehicles I currently use over the road are a '91 Ford F250 heavy duty 3/4 4X4 diesel auto and a '97 Ford Aerostar 4X4 with the 4.0.

The '91 gets 20 mpg if you keep it under 60 on the highway, with a personal best of 23.6, it drops to 16-18 in town depending how much I am rapping the pipes to drown out the buzzy rice grinder next to me. Of course the nearest town big enough to have these is 100 miles away so it doesn't happen very often. It does drop to 12 if I tie on to something really heavy.

The '97 gets 20-22 highway with midgrade fuel under 70mph, regular drops it down to 17-18, 16-18 in town(the 4 blocks to the other end of town to work for my wife).

Diesel fuel is now cheaper than gas so I will probably be running the pickup more than the van down the highway.

[BINGO53]

My partner and I tend to lead rather sedate lives.(translation: boring) We each average less than 5 miles/day. I keep track of the Saturn, and have consistently gotten 18mpg +/- a couple tenths of a mile. This is strictly driving in the neighborhood. Once I got it out on the highway and got better than 25 mph.
My partner has taken over our new '07 Equinox. I have not been able to get an accurate reading as she keeps accidently throwing away the slip of paper that I jot down gallons and miles on when I fill up HER truck. The "little man in the dashboard" (DIC) says we are getting 14.5-14.9 mpg. But again this is only slow poke driving in the neighborhood. About two weeks ago we did make a trip across town on the freeway and dash indicator read 19.5. I will hide my notes, and get a better figure. I'll post later.
I would be very interested to hear of the REAL figures (not dashboard read-out) from other Equinox owners.
Both vehicles are bone-stock and in tip-top tune and condition.

Respectfully,
BINGO53 :great:

[dbledsoe]

I wonder about changing the differential (both of them) from the 3.73 gears to 3.08 or something like that. Acceleration would suffer but that's ok. Most of my trips are 30+ miles and I rarely tow anything bigger than my lawn mower.
Do you think 3.08 would increase the mileage by the corresponding 21%. If so, it would pay for itself in about 35000 miles.

[jhuffman]

I'm getting 10-12 MPG, but all I do is drive locally. No idea what highway mileage would be. Any suggestions on improving performance?

[TrailLeadr]

Well, I thought so too, but a local car guy on the radio (Ed Wallace) said on his show a couple weeks ago that the average is about 10-15% worse mileage when it's raining. I guess it's because of an overall lower co-efficient of friction.

In that case, I should think that it would even itself out to a point. Since you may encounter slippage at take off, that same lowered friction should allow the car to travel easier at cruising. Less rolling resistance, I would think.

Holy cow this thread exploded!!! lol When I started to respond to Steve's post, there were only 6 posts....now there are 24

[maxumpower]

MY 1991 Blazer with the 350 doesn't do to bad. It has dual shocks all the way around, electric fan, underdrive pullys, power raid TB spacer, jacobs electronic ignition (MSD) Free flowing exhaust with full length headers and an H-pipe with no cats. I towed my 20 ft boat about 50 miles round trip and burned less than 1/4 of a tank. I was also driving like that little old lady i had to race in my sonoma!

[lrod8]

i get 16.5-17, 07 suburban 5.3 stock. i'm gonna keep driving stock a few more weeks and then install a cai to see if it helps...

[pBo7]

My 07 Colorado (4cyl, 5spd) gets around 23mpg mixed 60% city and 40% highway driving. I'm expecting it to increase though as it only has 3200 miles on it.

My previous car was an '03 Subaru WRX. I averaged just under 20 mpg if I was light on the gas, and around 17mpg if I got on it.

My '04 Cavalier got 32mpg driving 100% city... (shoulda kept it, graduation present = no payments)

[Caliz71Tahoe]

'05 Tahoe gets 14.9 MPG and the '96 Z71 gets NOTHING...tranny blew last week. :mad:

[mjbell1]

My 2005 Silverado V6 gets about 20mpg highway.

Truck has K&N Cold Air, MSD Ignition, Cat Back dual exhausts.

It would probaly do better with a lighter foot.

That's pretty good mileage for the Cavalier. I would have thought the Colly got higer mileage for an '07.

[bob_w]

My 2001 'burb gets about 17 highway & 13 city. It has 109k on it and still runs strong. It has gotten as high as 22 on the highway, but that was 80k miles ago before I started trailering a lot.

Bob

[dpgj]

I have a 2005 Chevy Colorado, extended cab, Z71 4X4 with a 5 cylinder enginer. I have been keeping track of this for some time and I get an average of 22mpg. I probably could get more but I have to jump on it some times. Unfortunately in New England there is no way to be "gentle" when you are driving. Has anyone heard about putting a little acetone in the gas to improve mileage? I have all kinds of stories. Some say it works, others don't. Some say they have been doing it for thirty years and get at least a 10% increase and others say it destroyed their engine. Any Chevy truck guys out there have any "REAL" information about this?

[jrgonzal]

2006 Chevy Trailblazer SS gets 9 miles to a gallon. It went up from the 8 MPG it got last year. Gas is $3.85 here. So much for the 15 MPG City on the sticker. I thought that was bad, now it would be a great improvement.

[rwhitbeck]

...electric fan...power raid TB spacer...

Any idea what influence these two items had on your mileage?? These are both things that I have been looking at for my '88 'burb'!

[retired2001]

On my Z71, I avg 18 to 18.5mpg consistantly. On the motorhome w/8.1L, I just moved up from 6mpg to 7mpg (breaking in a little more). Right now I am pulling the Z71 behind the m/h and getting 7, so I am hoping for a little more improvment! It is a major undertaking filling both up at the same time!

[rwhitbeck]

...has K&N Cold Air, MSD Ignition, Cat Back dual exhausts...

Any idea what these items do for your mileage...more stuff that I was looking into for my '88 'burb'!

[Bonzai01]

Hi, 88 GMC Suburban ("too" High Sierra) used on a daily commute of about 20 miles round trip...350/throttle body FI/auto tranny gets about 13mpg. Just filled the beast up last nite to the tune of $75, ouch. Every time the gallon clicker went off I kept hearing the media telling us the oil companies have more money than they can get rid of and how they have nothing to do with the supply and demand cost increases...right, and I still believe in the easter bunny too. I for one am damned tired of companies paying monster salaries while the consumer foots the bill for new equipment, expansion, etc. Isn't that supposed to come out of your profit margin?? It's called the "cost of doing business"...pardon the rant, just sick of it all...now the local power conglomerate wants to raise power rates while they pay the highest salaries ever recorded within their corporate structure. I got a whole 3 percent increase this year, we're almost "up" to the government poverty level now!! Whoopie.... Kerry.:confused:

[rwhitbeck]

...pardon the rant, just sick of it all...

Nothing to pardon as far as I'm concerned...I feel the same way about big corporations!!! I grew up in a county...yes, county...that was around 3500 people when I was young...everyone in town knew everyone else and we believed in fair treatment for everyone!!! Big corporations should take a cue from small town America for a change!!! We have the same issues here with our power companies...depending on which side of which street you live on here determines the power company you're allowed to have...and they can certainly jack the prices if they want to because our state and local government are spineless wienies that won't stand up to big corporations...hell, they won't even stand up to little gas station owners when they charge $6.00 a gallon for 87 grade gasoline!!

Yes, I have my own rants...big corporations and governments are only a part of them!:grrrrrr:

[hollywood49]

95 suburb 10mpg 350 auto 4wd oversize tires 160??? miles i am sure its lower now as i checked before started dragging 3500lb racecar around twice a week
96 f150 14mpg 4.9 I-6 auto 2wd super cab long bed 145??? miles my work vehicle 4mpg is 4 mpg suburb nicer but f150 cheaper to run

[maxumpower]

Any idea what these items do for your mileage...more stuff that I was looking into for my '88 'burb'!

The same trip before all the add ons sucked over a 1/4 tank of gas!
The truck runs much smoother. The only thing is that these things cost money so you would have to keep the truck for a while to get your moneys worth.

[Davandy]

GMC Savana 87000 miles on it 10.23 MPG city :neutral:

How do you drive it? Light on the throttle, or do you try to catch rubber on each green light? :neutral:

The new corvette will get 25 MPG highway, if you lay off the throttle and drive it like a Malibu. However, pedal to the floor will get you like 10 MPG.

[claptonfan1]

2006 with a 496 CI daily to work we get 11.5. Thats with 12 miles of interstate and 5 miles in town one way, round trip 34 miles.

Towing a 8,000 lb toy hauler to Florida in March I got 7.5. The burb towed like it had nothing behind it even through the hills of Tennessee on I-24.

[collinsperformance]

i still do not know the TACH or gas guage as they both move too fast...lol
we are getting almost 18 MPG with Brutis since the new fuel pump and cap/rotor/wires. we were getting less than 10MPG before the repairs. we are running the AC almost each time since the window switch died and i not been able to replace it. and 40% of the time we been towing a trailer from and to the new and old home....mike

[joshua022]

I have a 03 silverado with a cam, stall converter, custom tune, headers, intake, elect. fans, and a few more bolt-ons. I get about 14.5 mpg city. Haven't had any long trips to fiigure up my highway mpg.

[davet1960]

my 92 S-10 has been getting 12

[GMMan4ever]

My 98 GMC Sierra 2500 454 gets 15 Mpg highway and 11 Mpg City. Towing it gets about 10 Mpg.

Wifes 06 Trailblazer EXT is getting 25-27 Mpg and she drives like a bat out of H_ll! I don't get it. I have checked it over three tanks of gas and it doesn't change much. BTW, even towing an 18' travel trailer (not a pop up) it still gets 16-18 Mpg!

I'm really loving my (ok the wifes) Trailblazer. She really loves it too! Has more room than her mini van did and gets better mileage, has tons more power and it's 4 wheel drive!

[txbatman]

I have an 07 Silverado Classic 5.3L V8. I installed Flomaster dual exhaust and re-programmed with the Hypertech programmer. I drive 50/50 highway/city and I average 19 MPG. Straight highway driving, I have had 24.3 MPG. Quite exceptional I would say.

[jepolleyia]

1998 Isuzu Hombre, 2.2L just recently purchased.

I've been driving it to work, all highway, about 14 mi;es since early April. Took a while for me to realize that I wasn't shifting into fifth gear soon enough on the highway. The truck is so underpowered it won't pull up a moderate grade in fifth gear so I was forgetting to shift into fifth. Now that I've caught on, it's averaging 22.5 mpg.

[KD7ONE]

Last time I figured it out, I was getting 11.3 Mpg with a 350 fuel injected engine.

[terry0341]

Gettin a steady 15 in town and a good 18-19 on the highway. I will take that any day over the old trailblazer with not enough room for the fam and a steady 10-12mpg.

[84fiero123]

At the price of gas lately I can’t afford to fill the Burb. to check.

Besides, it’s a Burb I got it for its usefulness to me, not its mileage.

Back to the topic...

formerly owned an 05 Colorado 3.5 reg cab 4x4 - 18-19 mpg. Now own an 06 Canyon 3.5 Crew Cab 4x4 - 18-19 mpg.

I have an 06 Chevy Colorado crew cab 4x4 and the estimated mpg are 28 highway and i drive about 50/50 highway to city and i get about 28 to 30 miles per gallon now but in the winter i got 24.5mpg

I'm very envious of this kind of mileage. I do an 80 mile round trip commute to DC daily in a lot of stop and go traffic.

28 MPG? Your Colorado isn't rated that high. The 4cyl/5spd 2wd is only rated at 26 MPG hwy. Best I've gotten with my 2 wd/4cyl/5spd is 27. I average 24.

Synthetic oil and 40psi in the tires in cruz control is how I got the 27 mpg on a 200+ mile run from L.A. to Fresno.

[impaladave]

I'm getting about 12 from my 03 silverado SS, about 16 from my 04 Tahoe, and about 6 from my supercharged 1996 Impala SS ( it's got 600hp ).

My wife and I both have a heavy foot, but those are averages for mostly highway driving.

Dave

[comajoe]

we have an '03 suburban w/the 5.4 vortec. our computer shows average 15.4 mpg, with about 80,000 on the odometer. we've actually got that up from 14.9, from the previous owner. no towing with our number.

[CharlieP]

The way i drive normally I only get 12 mpg. if I would keep it at 55 my mpg wpuld jump to about 16.

Charlie

[Oatdog]

I usually get 14.9 by the onboard computer. I haven't really tracked it in detail. That is around town driving.

[c0zm0]

I have a 93 K1500 with about 2K miles on a rebuilt 350 and tranny.About 12 MPG but she's pretty tight still, so should improve a bit.

[TB~Mike]

We just took a 700 mile trip in our 4x4 06 Trailblazer today with the 3.73 rear end ratio and we averaged 19.5mpg the whole way with the air on. I had the cruise set at 77mph 90% of the time. Rest of the time we were going 62mph.

I would have loved to drive my G6 with the V6 which gets 31mpg all the time for me but we couldn't get all our crap in the car :(

Anyhow, after that 10hr drive I'm off to bed!

[maxumpower]

How about a flying car? Less gas. less time. Of course it would have to be chevy...maybe a blazer with the top down!

http://travel.howstuffworks.com/flying-car.htm

[inspectormatt]

I get about 10 mpg around town in my 84 Suburban.

[rentrimillos]

I have an '06 Sierra, 5.3L crew cab. I installed a Volant CAI about 7 mos ago and the last time I check my mpg I was getting 19. I installed a Magnaflow cat-back system about 2 weeks ago, but I haven't monitored the mpg yet. I hope it's doing better. I'm thinking of installing an after market MAF and TB spacer for a little more power and hopefully a little increase in mpg. Any thoughts?

[SeeClamp]

My '05 Colorado (I-5 engine) averages around 21 MPG. My '94 S10 did better at 24 MPG. Just another testament to the fact that the Colorado is underpowered for its size.

When will they offer the 4.3L V6??? I think the GM Engineers should be thinking about that. I wish I had the $$$ (not to mention the know-how); I'd retrofit mine.

I miss that Vortec V6!!

4.3 is gone. Its not used in anything I don't think.The current 4-5-6 cyl inlines use some of the same internal parts (rods,pistons,etc.) so it's cheaper to produce. Had a 1997 Isuzu Hombre (S10) with the Votec 4.3 and my Colorado with a 4 cyl will run right along side with better MPG, but the 5 & 6 are fuel guzzlers I'm told.

[armand71]

I am from Canada so with the help from some conversion tables I am getting around 15 miles per gallon! My daily commute also involves driving over a mountain and average's around 250 miles per week...so it's not cheap but it is the best truck I've owned. The last truck I owned was a 1991 S-10 with a 4cyl and a standard and for the same amount of miles it cost me $5.00 less per tank! You can't even compare the two vehicles. I love my Tahoe.:biggrin:

[oakrad1]

I am getting 14 mpg overall according to the onboard computer. If this sounds right somebody yell back at me as I just got this truck 2 weeks ago...

[dwill3015]

welcome to the site oakrad1. Raiders fan are we? I have been a die hard Raiders fan since I was a little tyke. I'm glad you found the site and is your Silverado a Classic or new body style?

[drgrcr74]

In the first 2 tanks of gas I have gotten 18 mpg out of the new tahoe.

[phoebeisis]

I bought the 1998 2wd Suburban(196,000 miles) 2 weeks ago.It got 11.3 mpg over the 1st 90.6 miles in pure,city,stoplight to stoplight,short trip driving.Most of this was in extremely short trips-2 miles-so it was having to warm up(run rich) each time. This is surprisingly good mpg for this sort of driving.Our 1000 lighter,smaller 3.5L V-6 motored,5 speed Honda Pilot gets about 12.5-13mpg in the same driving,so 11.3 is pretty decent.My Titan would get about 12 mpg(500lbs lighter, much newer),Tundra got maybe 13 mpg.Prius would get 38-40 mpg in the same driving, Prizm(corolla clone) would get 20 mpg same driving..
I'm pleasantly surprised it did that well.I was ready for 9 mpg.
I'm happy.Controlling for weight, it does as well,lb for lb,as a much more modern,Honda Pilot.Honda makes very FE motors,so that is pretty decent.The Pilot is AWD but it doesn't really seem to effect the mpg much.
Thanks,
Charlie

My 08 Escape gets 24-28 depending on how much AC I run. My 05 Sable got a consistant 27 and my 85 C-20 with the 454 believe it or not 15. Pulling a trailer I get 12-13.

[ChevyTech]

My 06' Silverado w/ the 5.3 get about 22mpg hwy. and 15 mpg city.
01' Catera gets about 24 hwy and 18 city
06' HHR is close to 32 hwy and 25 city
80' c/30 1 ton get 3 feet to the mile hwy and 1 foot city:biggrin:

So far it looks like 11.5-12 mpg :eek: (50/50 high/stop&go). The wife and I are going camping this weekend so I can check it on the thruway.

99 Alero 28 mpg w/ the air going 89,000 mi, 2.2 (?) 4 cycl. (and we're selling this?!?!?!)
05 Mazda 3 32mpg (wifes car) 10 mi back & forth to work. When we first got it we took to Norwalk OH from the Buff and we got 35 mpg at an avg of 75 mph. Coming home at 65 mph got 40mpg.

[TomsHHR]

2006 HHR, 2.4 auto, 28.5 on 87 proof in town and 32.2 with premium on the highway.

[TA Dave]

Well the first tank of gas thru the Burban got me 7.2 mpg with mostly city driving... Ouch!

Looks like it's time to check the tune up, and call for a computer chip too. ;)

[phoebeisis]

I'm happy.In pure city/short trip driving I'm getting 12 mpg over the 1st 150 miles of owning it.For a 10 yo Suburban(1500) with 196,000 miles on it,that is OK.
The same driving
1980 Dodge D-100 318 MT got about 12 mpg-13MPG(weight maybe 3700 lbs)
1986 Toyota truck MT-22MPG(2600lbs)
2001 Prizm-21 mpg(2800 lbs-AT)
2001 Tundra 13 mpg(4400 LBS-AT)
2003 Pilot AT-AWD 14MPG (4400 LBS)
2004 Titan 12 mpg(4800 LBS AT)
2006 Prius 42mpg (2950 lbs)
1998 Suburban 12 mpg(5300 lbs,I guess)
I just sold the Pilot,and the Prizm.Have the Suburban,and the Prius now.
Thanks,
Charlie

[Hookjr1199]

My 1994 K2500,4x4 suburban with the 454 gets about 12.5 on the high-way don't know what it gets around town. I only use it to drive to work which is 4 miles away and a tank usually lasts me about a month.

[drgrcr74]

Well I never figured it up till now, the 1970 Duster drag car burns 4.2 gallons per mile. Of Alcohol, and that milage includes a big smokey burn out:great:

[iraceIHRA]

Well the milage keeps getting better, but I am sure I am plateaued at 15 mpg :happy: . I am going to put a K&N filter on it and see what that does for me. Guys w/ PU's if you have a tonneau cover, what is it worth for gas milage? I am considering a soft version, low weight and I can have one that is hard, need to put snowblower in back in winter.

[Cableguy]

:lol::rofl: OMG now thats funny!

[drgrcr74]

1970 Duster 4 link, 12 pt cage, ford 9", 5.00 gear, power-glide, 472 stroker motor (400 block). roughly 720 rwhp, 3000# with 230 pound driver, runs 9.80 135-140 on the quarter mile. EXPENSIVE TOY

[Skarch]

My GTI gets about 30 in the city, 34 on the highway. If I swap in the TDI 5th gear (.756 I think) That should get me closer to 37-38, cause it would bring my RPM's way down. As it is, 80MPH is 3500 RPM's. Id Like to bring it back down to about 2300.

The Passat gets 16 or so in town, and pushes the 30 mark on the highway.

Both of these are 1.8 Turbos.

I have no idea on the 'burban, as it isn't here yet, but I would assume somewhere between 12-15. My wife will use it to drive back and forth to work, about 1.5 miles each way. And we will use it for hauling stuff and when we go on long vacations. My GTI is the weekender/errand boy. You'd be suprised what will fit in the back of that with the seats down.:party:

[Steve]

Since I did my fuel system cleaning with RXP and I changed out my air filter, I'm now getting about 27 MPG in the cavalier.

I'm right in the middle of getting a historical reading in the Trailblazer. I am going to get my PCM programmed by the guys at PCMforless later on this month and I hope to see at least 1 MPG difference, but I won't be surprised if I see more.

[Cableguy]

I am going to get my PCM programmed by the guys at PCMforless later on this month and I hope to see at least 1 MPG difference, but I won't be surprised if I see more.

I wish I lived closer to check them out. I wouldn't mind doing that to my TB.

[Grynder]

The Buffalo gets 10 mpg, ...........period.
I drive our lil Samurai most of the time around town, about 20-25 depending.
The wifes '07 Charger gets 20-22 when she drives. About 17-18 when I drive.

[Steve]

I wish I lived closer to check them out. I wouldn't mind doing that to my TB.

They have a mail-in service option. They'll send you a PCM programmed to your specs and then you send your existing PCM back to them. I think there is a sligh core deposit, but it's not much and you get it back when they receive it.

[TA Dave]

Well I'll be darned!

I finally finished all the testing on my 93 2500 'burban, 7.4, 4L80E, 4x4. All stock with the exception of True duals and a K&N filter.

Towing my 28 ft race trailer, at a tick under 10K, in a combination of Hwy and secondary roads I got 7.8 MPG. (Not fricking bad, considering)

Now I've just taken the family on a road trip from S.W. Florida to Kentucky, then Norwalk Ohio for the Pontiac Nationals. On I-75, with the burban loaded down with 5 people and luggage for 10 days, I got 13.9 MPG running 73 mph over the entire state of Georgia.

I have to say I'm very impressed, and thought it would have been much worse. The temps did climb some (from 170 to 200) going thru the mountains north of Knoxville, but it could maintain speed without extra measures.

[manny]

my 98 gmc 5.7L 2wd has 177000 miles and still gets me 16-17 miles to the gallon depending on the driving conditions some times even better and no regrets buying the truck

[Steve]

I don't think I have to worry about what kind of mileage I get in my wrecked Trailblazer anymore! ;-)

I still get better than 26.5 average in the Cavalier.

[FireRed]

I have a fairly decent side by side of my 02 Burb and mt son in laws 03 burb, mine is 2X4 his is 4X4 other then that they are a match both having mid 50"s mileage wise. He gets 12ish in town an upper 16's highway, my 02 get high 15's town and pushing 18 highway. I run 35 miles each way at 70+ he drives about the same.
Now the real puzzler!!! My 97 2X4 GMC Burb with 142,000 gets 15-16 town and really gets very close to 20 highway, I thought the new one would do a tiny bit better the the old one. I think the higher usage is due the newer one being a lot higher and also running larger tires, it is pushing more through the wind. All of the above have 3:73 gears and tow packages, the 97 has done the most towing. It has gone from Long Island to the 1000 Islands 3 times towing my 22 foot power boat, towing at 70 it gets almost 14 so I lose 5 mpg towing. I was going to sell the older Burb but now I am just not sure, may let the new one go.

I towed a trailer, with a 4000 lb car today , used just short of 1/2 tank for 210 mile round trip

[LSD_Vortec]

I have an 07 Silverado Classic 5.3L V8. I installed Flomaster dual exhaust and re-programmed with the Hypertech programmer. I drive 50/50 highway/city and I average 19 MPG. Straight highway driving, I have had 24.3 MPG. Quite exceptional I would say.

I've been looking into the programmers as well. They allow the engine to make use of every drop of fuel, hence the extra mileage and power numbers. I think that having a K&N FIPK system, new program, and exhaust help these trucks inmensely. I am definitely doing all three before next year.

Well my turck gets 17.8 in the summer in AZ, and about 19.2 average in the cooler months in town. Highway a/c or not i averaged 23.5 on my way to and from Topeka, KS last 4th or july. Thats why i bought the little V8, reg cab, short bed, shes light, lol. After i get my hard bed cover (gaylord), and do some small engine retuning ill be in the money.

Oh and i almost forgot. My mustang gets about 28mpg city or highway. Everyone wants to know why i dont drop a big v8 in it, lol. Ha with that kinda mpg and about 35$ amonth for full coverage. I think not. Plus shes a show'er not a go'er.

[Holy Smoke]

Do you use your 59 that much to need better mpg? I've owned a 68 230 ci. and now, a 70 350 ci. I get 18mpg on the 350 c10 1969. let me know if your driving it abit.

I filled up today and I got an amazing 11.16 MPG. Life sux :glasses:

Filled up yesterday and got 18.42 mpg. Sat almost a hour in stop and go traffic on the freeway too.

[OLD BLUE]

I Have A 1990 Suburban 2 Wheel Drive With A 700r4 Transmission And This Past Summer In Close To Idle Conditions And Cruise Set At 110 Km/h I Got 23.3 Miles Per Gallon In Overdrive Which I Thought Was Amazing For A Big Suv. And I Have Confirmed That Over And Over Until The Weather Got Colder Of Course In Which It Dropped To About 18 Mpg. THE BURB HAS 295000 KILOMETERS ON THE ODOMETER.

[gmcjimmy88]

mY 05 gmc Seirra 2500HD gets around 9 MPG in town. Best tank has been 12 MPG on the flat open highway with the cruise set. My Focus gets about 20-22MPG's. The others do not get driven on the road enough to know.

You touch on a good point. Driving style really does make a major impact on your MPG. The same vehicle, all things being equal, one driver might get 20 MPG and other gets 12 MPG, just becuase one takes it easy and another is heavy on the throttle.

[GM_Guy]

one of the options My 1976 Buick has, is a color coded fuel usage gauge, as part of the speedo cluster. it reads low usage :green, medium usage :yellow, and high usage :red
I have found it very useful so far. here's a pic showing it: it's in the far right corner of the pic

averaged 11mpg city, 15mpg highway

After...
average 12 city (killed by the fact that I drive short distance to work)
average 17 on the highway (I've gotten up to 18.5 when driving 65mph)

[GMC/Jeep]

My 2000 1500 2wd w/ 4.3 and 5 spd is getting 18mpg in town, just installed a K & N FIPK so next fill up I should see some changes and hiway driving outcome. I'll gladly take the 18mpg I'm getting now over my 99TJ's 8-10mpg.

[finalday7]

Does anybody get less then 11.5 avg?

[stubby]

I've installed a hydrogen generator on my 95 ford v-8 and have increased my milage about 25-30 %
it was very simple and cheap, used a ball jar w/plastic cap plastic insulators and stainless steel
welding wire to accomplish the hydrogen generator, hooked it with a relay and fused w/10amp fuse,
it turns on w/my key, check out thee site it's called "water4gas", it will increase anyone milage!!

[PontiAddict]

I get about 16 average in the avalanche. Highway mileages are 24 @ 65, 21 @ 70, 18 @ 75 and 16 @ 80.

I should drive the bonneville more. I get 25 avg out of that, 20 city, 32 highway.

[stubby]

Stubby Here, as of my last posting , in my 95 t-bird, v-8 i haven't had a road trip yet,but around town i'm getting right at 35mpg(34.5) up from about 18mpg average using the hydrogen generator. now that is keeping my foot out of the throttle, just normal traffic driving, sometimes i have a bad habit of playing with my new found power range, very good acceleration, then i get about 28mpg.

[Pete95Sierra]

damn i wish i got 28... right now in the winter im gettin 11... in the summer i do a little better at a little over 12 usually

[johnnyr]

Hi, just joined!

Usually I drive about a mile to the train station, and that will get me around 13 mpg, sometimes better. On a road trip, all Interstate, I got 26 mpg on my last test. I'm looking at an electric fan for the next step to improvement.

Any suggestions?

[OLD BLUE]

Last Summer In Ideal Conditions I Got 22 Mpg In My 1990 Suburban With An Overdrive 700r4 And Averaged Around 60mph On Highway And Now That The Cold Weather Is Here I'm Getting About 15-17mpg On The Highway And About 12mpg Around Town Now And Was About 17-18 In The Summer Around Town. This Is Only A 2 Wheel Drive Burb As Well. So I Can't Really Complain At All. Actually I Was Very Pleasantly Surprised Last Nsummer.

[Steve]

Anyone working hard at increasing their MPG?

[RatRod]

I am working on it to save by being light footed on the throttle. Still getting 18 MPG combined driving.

[dryfuss10]

I get about 28 on the highway and 24 in the city, Its all stock

[finalday7]

Steve Anyone working hard at increasing their MPG?

I'm doing the little things. Programmer ( helped a ton) new muffler and next will be the intake.

[mvoss2576]

I'm getting an average (highway/city) of about 15.5 - 16 with my 07 Classic Crew 4x4 with the 4.8, I leave my bedcover on most of the time too, I dont know exactly how much it helps.
I run Amsoil in my truck's engine, and want to get the tranny and diff done with it too.

I am thinking of a muffler and a programmer sometime in the future... but right now, my wallet is a little too thin from just putting fuel in it..

[SSAZ]

2007 TrailBlazer SS - I drive 60-80 miles per day, all city, and average about 13.9. But heck, it DOES have a Corvette LS2 in it, so it's no big surprise. And the FUN FACTOR definitely makes it worth it! :biggrin:

[flag8r]

I've had my 5.3L w/Active FM 08 Silverado Crew Cab for about a month now, and the first two tanks were horrible about 11.8 with a steady mix of city/hwy, and was really worried but I guess it was just engine break in because I'm over 1000 miles now and the third tank got 16.2 city/hwy. So if that keeps up I'll be happy. Been driving it with a feather foot most of the time.

[bkovacs]

I get about 12 MPG with my suburban with the 7.4L, about 13-14 in the truck with the 6.0L

[phoebeisis]

I just drove from New Orleans to Flagstaff AZ -1508 miles-in my 1998 2wd Suburban 201,000 mile 1500..I drove with the CC set on 68-70 mph with 43 psi in the fairly worn tires.I use Mobil 1 5W30, it used about 12 ounces of oil.
I got 20.8 mpg-much better than I expected.I'll post the return trip in a few days.I doubt that the good mpg was because of favorable winds-usually the return trip gets me 1-1.5 mpg better(done the trip many times, 1st time in the Suburban).
My city mpg is nothing special-I work hard to get 14 mpg-gliding a lot.

Obviously I'm pretty pleased with the mpg.We drive straight thru-sleeping in the vehicle at rest stops-so very big is very good.We have a futon mattress in the back for us-and the dog-to sleep on.TX has great rest stops with lots of activity/trucks/lights and the dog will bark,so it isn't too dangerous to sleep there.A motel would be nicer, but $80 is $80.The back of the Suburban is free.

[ebollard]

i never have any pity for any of my friends when they dont want to drive because of gas prices. my 86 gmc sierra 5.7 gets 8 mpg sooooooooooooooooooooo bad

[MWright936]

I'm getting an average of about 17.5 mpg with my 5.3L crew cab with a mix of city and highway driving. Pretty much all of my plans for future mods are geared toward increasing that number. Next will be exhaust, followed by programmer, then possibly a tonneau cover (researching that now to see if it's worth it....has anybody seen noticable increases with a tonneau????), then maybe an aftermarket MAF. Somewhere in there I will probably also replace plugs and plug wires to get some more spark. All of this sounds good, but it's going to take me a WHILE to get it all done. Evidently, all these things cost $$! :money:

[gotchapunk]

Wow MWright 17 must be nice im getting about 13.6 with flowmaster 40s and mostly short in town driving.I just put a K&N filter and a Helix throttle body spacer hopefully that witt help my MPG. Next is a superchip. I hear those help alot

Well, I do kinda baby it. If I drove it like I wanted to, I would probably get what you do. It takes some serious restraint to take it easy on the gas pedal. Especially since I went from having a 2.3L 4 cylinder to a 5.3L V8 when I bought this truck a little over 2 months ago!!

[dryfuss10]

I get about 27 mpg 50/50 driveing I do like that 5 cyl motor it does well

[BigRedChevy]

I get about 27 mpg 50/50 driveing I do like that 5 cyl motor it does well

I had a 04 colorado before this truck and the best i ever got was 18 mpg. My dually will get 19 hwy, 14 city, and 15.5-16 combined driving.

[DOZER1]

I did a test over the last tank of gas, mind you it's been raining so I expected to get at least 10% less fuel mileage because of tire slippage.

My 99 Cavalier got 25.6 MPG over the last 268 miles. Not quite as good as it has been, but as I said it's been raining and I've been driving it more for short trips lately because it gets better mileage than the Trailblazer.




Just got back from Las Vegas on Sunday and I was getting 15.2mpg if my math was right.LOL. Thats alot better that I thought I was going to get. That's better mileage (12mpg)than I was getting on my 5.7 Dodge Hemi1500 4x4 and that had a K&N CAI and Flowmasters??? I'm hoping that once I add everything to this truck my mileage doesn't take a dive.

[kelpet]

2007 Silverado 6.0L Crew, 16K in 10 months, 16mpg avg, 14 low, 19 high. Wish the 4 cyl mode would stay engaged just a little longer, seems to have plenty of power. I drive like my grandmother, "Keeper of the Speed". Go ahead, flash your lights at me, were not on the Autobahn, I'm oldish, have great insurance and a 5 star crash rating.:lol:

[PontiAddict]

Averaging about ooh, 15.5 with the 65% city driving I do....averaged 17.5-18 on my 4000 mile road trip...but that was with 3 people, and the back absolutely packed full. Not horrible if you ask me for a vehicle of this weight.

Bonneville will average between 28-35 (55-75 mph)
Averages about 23 with mostly city, some highway driving...but that's with a lot of on off highway, so getting up to speed, and only staying there for 5 minutes or so.

[Family Force 6]

Our 2nd fill on the 99 suburban 5.7, mostly city driving was 14.1- not bad. I'm anxious to see how it does on the open road as it seems the rpms are pretty low at highway speeds.

My 78 suburban (454) got about 10, regardless if I was towing or driving highway, and if I took it above 70 it started to drop to 8 and lower.

My 88 corolla commuter is carburrated and gets about 30 in town, 36-40 highway driving. I actually got over 50mpg one trip coming down from 9500ft in the mountains back to Denver over 200 miles.

[retlow8]

My '04 Collie I-5 got 24 mpg est. average last tank.

[ct9a]

My '94 burb 5.7L just gave me an avg. of 13mpg hwy. The best was 15.xx mpg and the worst was 11.xx mpg. City driving I've been getting only about 9 mpg.

[MWright936]

After I got my exhaust, I got 17.5 average city and highway (a little more highway than city). Then, I tried going no faster than 60 back and forth on my commute to work (about 50 miles round trip) and I got 18.5 on that tank. Now I'm trying just going the speed limit (instead of about 5 over) to see if I get the same. I'll be happy with about 18, then I plan on getting a programmer eventually that I'm sure will help as well!

[cascott325]

i have a 2000 silverado w/ a 5.3 vortec
i used to get b/w 12 and 15, 16 on a great day with exhaust, k&n cold air, and shorty headers. after changing to iridium plugs, 8.5 mil wires and recharging the filthy filter (it was completely black from the prev. owner), and switching to penns oil platinum full synthetic, i get low 14's when im really playing alot, and mid 16's when im not. i had to go to michigan to pick up my girlfriends car w/ a 2 wheel dolly and even hauling the car doin 80+ the whole way i got 19 mpg highway. i forgot what it was without the car.

[johnvosh]

In my 2003 Chev Cavalier (2.2L 5spd) I get anywhere between 28MPG to 39MPG. IF I do straight highway and keep it under 115 KM/H I can get it up to 39MPG. In my 94 Suburban (5.7L) I think it gets between 13-18 MPG. It is hard to tell because I get FREE gas from work and there is no meter telling me how many litres I am putting in. In my 1994 Chev Lumina APV (3.1L, 3spd auto) I get around 18MPMG city and over 23MPG highway. But since I get free fuel I don't really care about my fuel economy anymore!

[raisor87]

my 98 xcab 5.7 vortec w/99000 miles gets 19 highway, and a whopping 10mpg around the city. No engine mods, just tuned up recently, tonneau cover and the bed is full of all of my tools.

What for rear gear was in that avalanche???? I do have synthetic fluids in the motor/tranny and a trueflow cold air intake as well.

the Cavalier can see about 20-25 but blower whine can get addictive and it will be lucky to see 15 combined

I just bought a '99 1500 4x4 'Burb and drove it back from Houston. 70-80 mph all the way and got just under 13 mpg and I'm not complaining. The leather seats, premium sound and smooth ride make up for any gas mileage issues, plus the fact it is replacing my C30 dually and I don't even want to know what mpg it's getting.
My '98 Astro Van gets 19 city.
I don't know what my '75 Blazer gets, again; whatever it is, it's well worth it....
