16mpg city. w/ 31s, injectors and drop in K&N air filter.

 

Pratically new 32X11.50 BFG MT's KM's not the KM2's

 

In summer my mpg never goes below 17. even with all city driving. if i drive highway no stop i can get about 350-360 miles out of a tank before the gas light comes on. the mpg indicator shows about 22, so with 10% margin of error for the 31s vs. the stock tire size i get about 24 mpg on all highway. but, my tires weight about 52lbs. a piece, so with lighter tires, it might be a touch better. i do have quite a bit of add-ons though. i might re-gear soon, just to relieve some stress from the motor and the tranny.

 

i have a 96 with 3.55 gears and 31's and i get about 13 mpg and i have a miss, im in need of a tune up

 

I had a miss and thought when i fixed it my mpg would go up. i was wrong. Does anyone know how to check to see if the cat is clogged?

 

whatcha lookin ta get fer them terdytu's?? =)

 

now gents, riddle me this. with regearing, does mpg go up? or stay the same. Id imagine stay the same cause all its doing is stockifying the new tires size.

but i really dont know

 

i thinkit might help bring it up to the stock mpg or close or somethin, im new to this as i am 15 so if im wrong please correct me.. ive got a 93 and im waiting to get my 31s and 3 inch rc lift , then i will definitely regear my jeep has either 3.55 or 3.73 but havent tried to find out wich, it came with factory tow package

 

Brings it up, but only to a certain point. Too long to explain, it's on here somewhere.

Im on 31"s, but my readings are null in void, because I can only brim up to 3/4 a tank, and between a 5speed, and header to full exhaust with a Flowmaster, I get on it everywhere with the stupid pedal.




I am an idiot.

 

LOL ! ! ! ! ! Now that's funny stuff. Haha!



But man, some of your guys MPG makes me cringe! Haha.. 7.1 MPG's.. sheesh!

 

Seems right around 15 city and highway. stock gears, 31x1050 BFG ATs

 

Nice ride, Bustedknuckle. I love a clean, moderate build.

 

i run 32s on my purple jeep im getting about 13-14 mpg

 

If you were to match the gearing ratio to that of what you have on stock tires, it would theoretically bring it up to near stock mpgs. But then you would have to figure in the weight of the new wheels/tires, etc. and the aerodynamic values you lost from the lifting.

However, I would say that gearing properly is probably the most surefire way to restore the power and mpg.

 

what kind of power loss do you get when putting on 31s should i wait to get 4.10s before i get some 31s?
