    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.

    Canadians.

    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 @RayVoy.

    Anyway, I wish my truck could average over 350 a tank but this stop and go traffic really sucks here in va beach. Alot of times I will average 14-15 mpg with a 5.3 again insert . 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.



    If at first you don't succeed, chances are, you are using too small of a cheater bar

    Current:
    1999 GMC Sierra SLT Z71 | 5.3 Vortec | Spectre Cold Air Intake | TransDapt TBS | Hypertech 30005 Tune | 2005 Chevy Tails | Denali headlights | AWS Bug Shield | 265/75/16 Mastercraft Courser A/T | "Ghetto" painted tailgate | Boss HD Speakers | 2005 Overhead Console | Dual Thrush Turbo Mufflers
    Future:
    Bigger Amp Alternator | Electric Fans | Oil/Trans Fluid cooler | Re-done exhaust | Paint | Interior Restoration/upgrade with newer model stuff | Window Visors (In channel) | Tint | Low-Profile Tool Box | LEDs throughout stock cab locations | And whatever is spurr of the moment

    I had to replace all 4 of my 02 sensors on my '99 Sub, found them on www.amazon.com 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.
