I have a 89 cherokee with 96 motor in it, 8" bds lift with tnt longarms and 35" pro comp xterrains, d30/8.25 axles with stock gearing and aussie lockers front and rear. I am getting 4.56 gears installed. What do you guys think I will get as far as MPGs? Not sure what I'm even getting right now as I just got the jeep a week ago.thanKs

 

I have a 6.5 inch with 34s and it only had 90,000 miles on it. Coming down from MT to LA (1650 miles) i was getting 22/23.. now that my exhaust is messed up and im down in the humid south i only get like 14/16
easy to test though... just fill up your tank and drive

 

Yea but I was looking to get an estimate of what id get with the 4.56 gears compared to 3.55

 

I have 4.10s.. if that helps you

 

2001, 80k mi, 4.5" lift, 33 BFG AT,s, Currie 9" front and rear, 4:10 gears, Waren Bumpers, Winch, Partial Exo, 5sp manual Airraid intake, Banks header. It's heavy.
14 MPH country and highway.

 

That's nothing like mine so its hard to compare

 

?

 

anyone else?
