    Talking gas milage.... better or worse?

    think this goes in here...

    anyhow, i filled the tank up the other day, (a whole 15.285 gallons from just under a 1/4 tank).

    with all the driving we had to do, we put on 303.6 miles on the old jeep before i dropped another $20 in gas this morning. still had a good quarter tank when i gassed up. got home & checked the trip-odometer... 316 miles. on basicaly a whole tank of regular 87 unleaded.

    the odometer reads at over 240,000 miles. last summer we took a trip up north (2.5 hour drive) & had to gas up again before coming home. we averaged about 200 miles per tank back then.

    so what's changed?

    what are all you getting?

    for a 20 year old jeep (inline-6, auto) that's pretty good gas-milage.
    i love my country , but scared to death of its government!

    Back in the Jeep life! no more small cars here!

    With the top on I get 16.7-18.4 (best) in the CJ

    With the top off, drops to 12-14.5

    and towing the 'Adventure trailer' drops it another 2-4MPG.

    This is with a fresh rebuild on the entire drivetrain, and an MC2100 carb on the I6.

    I'm geared at 4:10 with 33's, really close to stock, as my speedo is within 5mph at 70.

    I get about 170 miles a tank on a 4 cyl 5 spd running on 33's. It was worse when I had the tires at 35 psi. When the tires were at 25 psi I was getting 125 to a tank.

    Since the lift the 200 miles a tank days are way gone.

    The Grand is running fine and we don't use the A/C hardly ever. A couple other people I have talked to said they are getting bad millage these days. Maybe the gas around here has something to do with it, I don't know. I've tried differant gas but it all seems to be the same except BP and it's worse.
