    The GM window sticker from my '91 Blazer says CITY MPG= 17 HIGHWAY MPG=22.

    My 4.3/700R4 usually average about 14-18mpg both in the city and on the highway. If I am heavy on the go-go juice, it usually drops to about 8-9mpg.[​IMG]

    I drive my '91 about 13 miles to work. It's about half side streets and half freeway. I check the mileage at every fill up, just to make sure that nothing is getting out of whack. It varies between 16.5 and 18 mpg, depending on the weather, driving habits, how many traffic jams I get stuck in, etc. [​IMG]

    My wife's 98 GMC Jimmy with 3.73's, 4L60E and 4.3 engine got 19-20mpg on her last trip from home to Spokane and back at 70-75mph cruise speed. Gets about 13-15 in town. Very impressive power, but no K5 for sure.

    I get very much the same results as sparkys wife gets, approx 19.5 mpg with no 4X4 time. My truck is a 94 modified with a K&amp;N filter charger and Flowmaster muffler.

    '95 Blazer, automatic trans, 3.23 gears, P235/75 R15s.

    I get around 16-18 in town, and around 22-26mpg with the cruise on the highway.

    Mileage is great, acceleration sucks, and so does climbing through the mountians out here. Otherwise, it's a great truck.

    3.73s are definately in this truck's future.

    Acceleration sucks? Wow, that must be a symptom of the newer ones, cause my '89 gets up and goes. Is your's a 4 door?

    '95 LT 4x4 4-door. It's the gearing... I've never seen another Blazer with 3.23 gears.

    It's not terrible, just slightly less acceleration that I'd like. 3.73 gears would help me a little, especially in the mountains.

    Could be worse, I'm carbed w/ the 3.4L and mild 700R4 gets me 12-14 on average, driven hard, mostly 45 and under.

    Altitude makes a big difference. Danno's up here in Colorado. Power is WAY down once you get above 6,000 feet or so. /forums/images/icons/frown.gif

    Yes, my truck is really feeling the effects of altitude. Lived all my life below 1000' feet, and now I'm running around over 5000 on a daily basis, and up to 9000' on the weekends.

    I need a turbo. Lack of oxygen sucks.

    Well, around town exclusively gave me 16 mpg.............happy as heck with that, since I'm not exactly light on the gas.

    Mixed tank of about 50% freeway/in town was 19 mpg.
