    My 99 Suburban gets about 630 miles to the tank. Is that about average for these 96-99 Suburban with a 44gal tank?

    I wish I got 22 mpg. But I couldnt tell you if thats normal for a burb. (Nevermind my math skill was a failure here:fighting0072:)

    That's about average (at least from what I'm getting). I have the 44 gal as well and I average right about 15 (sometimes a bit higher) on the highway. So, If I drive from full to bone dry and all highway I'd get 660miles out of a tank. When I bought it in 2001 with quite a few less miles I averaged right at 20 on the highway so I'd get 880 out of a full tank. So, in short yes I'd say that's right on par... Greg

    I also have a 1999 burb and I get about 660 out of a tank.
    Btw are you sure thats a 44 gal tank cause I still have my original window sticker and it says 42 gal tank.

    Ok! I bought my Burb in 2002 with 49,000 miles on it. Now it has 217,000 miles and still runs strong and doesn't use oil. I do all the Maintence my self. It still has the factory water pump. Replaced the fuel pump twice. Just did the front suspension( a-arms bushing, ball joints, idler arm, pitman arm, outter tie-rods, shocks, Trans, brakes and new set of tires). Also the drivers door hinge bushings. It's my HWY vehicle. The down side is the price of gas to fill it up. Here on SoCal gas is $3.65 a gallon. It's a $100 to fill it up from a half of tank.

    surprised its 3.65 / gallon in California. here it is 3.29 /gal.. most times your prices are at least 50-70 cents more /gal than out here ... [oil company fuel stations]

    It funny you mention it, the owners manual for my Silverado says the crew cab short box 1500 has a 26 gallon gas tank.

    I have ran the fuel tank down to where the needle is below empty and I only put back in about 23.5 gallons.

    The best I have gotten total miles out of a tank was about 410 miles.

    I'm on the opposite of that. My truck is supposed to have a 26-gal tank but I have ran it to E and put 27.5 gallons in it one time. I got right around 400 miles a tank when it was new but now it gets 350 at best.

    My '99 LS Sub gets about 20-21mpg. Drove it from Plano, TX to almost the AL/GA line 732 miles before I chickened out and out more gas in it.

    A recent study found the average Canadian walks about 900 miles a year.

    An other study found Canadians drink, on average, 22 gallons of beer per year.

    That means, on average, Canadians get about 41 miles to the gallon.

    Haha [MENTION=54249]RayVoy[/MENTION].

    Anyway, I wish my truck could average over 350 a tank but this stop and go traffic :grrrrrr: really sucks here in va beach. Alot of times I will average 14-15 mpg with a 5.3 again insert :grrrrrr:. I've filled up from empty and put 21 gallons in, above empty and put 23. Must be the fumes and vapor lock in the tank. Need to replace a pi$$ed off oxygen sensor so my CEL light will go off.

    I had to replace all 4 of my 02 sensors on my '99 Sub, found them on for just under $120 for all 4 and replacing them was easy. Didn't mean to hi-jack the thread....

    Get 20-22 mpg in my 89 Burb. If I'm hauling my small trailer (less than 5k) then I'll get ~17-18 mpg. Around town, a measley 13-14 mpg, if I'm lucky. The longest I've gone between fillups was 800 miles, while looking for an open gas station the last 50 miles on the highway. In town usually fill up at about 400. Having a 37 gallon tank is nice.
