    what kinda of fuel mileage do you guys get?

    i know we dont usualy talk about gas mileage much but i was just curious as to what kinda mileage you guys are getting and with what setups and city/hwy.

    in my xl with 265/70/16 tires at 40psi (i believe) 3.73s intake 93 tune magnaflow muffler in city is usualy 14-15 but last month we made a trip to norfolk va about 190ish miles from us and the wife was driving and when we got there i toped off the tank and we had ran 189miles and i put in 7.5gal at the point it was almost coming outa the filler spout. thats freakin 25mpg!!! the weather was in low 60s near us and got to the upper 60s low 70s when we got to norfolk.

    In the summer I average about 25, in the winter it drops down to about 19. Only difference being about 20# at each corner difference between my summer and winter wheels and tires, and a couple hundred pounds of sand in the bed.

    5.3, 3.73, 255/70/16's, i average 15-16 with my regular driving style, but best i got was 20.2 mpg with the cruise set on 65 for a just under 1,000mile round trip. i just got new exhaust yesterday, so i'll report back later.

    Yeah my mileage suffers more when i drive especialy around town or when and my friends are goin out cause usualy we tend to get in a hurry (strip clubs ) when i went and got my new motor for my 86 k10 i had to drive to hermitage pa about 357 miles from us rougly 6hr drive each way. Well i was determained to make good time and kevin needed to be home by 6pm. We stoped a dozen or more times for food gas him to smoke and getting the motor we left here about 7am and got back about 6:30pm we hardly ever did below 80 and when the gps took me through deliverance WVa we did a 120 blast a couple times :p so i only averaged 16.5 on that trip lol
