    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.

    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.

    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!

    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.

    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:

    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!

    Gas Mileage

    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.

    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!

    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.

    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.

    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...

    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.

    Mpg

    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.
