WN1998 Posted December 21, 2006 Share Posted December 21, 2006 I will soon be purchasing a 92 eliminator with a 4.0, 2 inch lift and 31 inch tires. What kind of MPG can I expect with this set up? Quote Link to comment Share on other sites More sharing options...
Oizarod115 Posted December 21, 2006 Share Posted December 21, 2006 my stock 1989 4.0l manual tranny gets about 17 but i AM a teenager, and i DO like the skinny pedal. mileage has ALOT to do with how you drive, if i drive it grandpa i could easily pull 20+mpg. 31s arent that much off of stock so you can expect like 18mpg if you drive normally.

jeepdoggydogB Posted December 21, 2006 Share Posted December 21, 2006 My mileage isn't that great, with the JC throttle body 3.73's and 31's I get about 14 with combined city highway driving. You got the HO MJ like mine, I wouldn't expect to get as good a mileage as the Renix guys. I know my mileage is a little off as I have the speedo gear for 30 inch tires on my 31's, and I am not sure if it shows me as going faster or slower.

I have the manual, but I also need to replace my O2 sensor as the Maint REQ light came on. When I first bought the truck the PO had it running with 29's and 3.33 gears he towed a boat. But I remember it getting about 17 MPG's, and 3.73 with 29 inch tires was a super fast! If it wasn't for my familiarity with HO stuff and all my diagnostic equipment I own for HO's I would have purchased a 1990 Eliminator with the AW4. If my wife had let me I would prolly own both.

500 MJ Posted December 23, 2006 Share Posted December 23, 2006 I was able to pull about 20-22 mpg with my AX-15, 31's and 3.55's on the highway. Quote Link to comment Share on other sites More sharing options...
pingpong Posted December 23, 2006 Share Posted December 23, 2006 MPG is over rated.... its all about how slow you can crawl up a face of a rock while bouncing off the rev limiter :teehee: Quote Link to comment Share on other sites More sharing options...

If you are talking about the MJ in your sig, those Renix jeeps IMHO just beat the crap out of HO jeeps in the MPG department. I wish the Mrs. had let buy the 1990 Eliminator along with my 1991.

500 MJ Posted December 26, 2006 Share Posted December 26, 2006 Yah, its just a plain 4.0. Lately my MPG has been suffering though thanks to my leaking gas tank O-ring. Quote Link to comment Share on other sites More sharing options...
