    Default What's your MPG?

    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!!!

    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!

    Default 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.
