I have a s-10 with a 350 V8, 700r4, 4WD on 36" tall tires and i'm getting between 12-15 MPG with an s-10 rear (4.10 gears) your rearend can't possibly be 4.8 to 1 because the s-10 rear will only carry up to 4.56 gear ratios. usually a stock s-10 rear will carry 3.73 or 3.45 gears in the 4wd and even taller gears in the 2wd. check out any local custom shop or store for new ring and pinion sets to buy. hey wanna buy some 3.73's from me, just a few chipped teeth :P
