Alright, I got my '13 JKUR (4.10 gear, auto trans.) on a budget boost and 35's just at 1000 miles on the odometer and I'm getting 14.5 mpg. What is the rest of the JK community in similar builds getting?
I'm right there with you. On my 2012 with 35's I get an average of 14.5 to 15. If I'm traveling highway on flat ground I can get up around 18, but that is rare. I have about 11,000 miles on it now and the mileage has improved a little bit.
'09 JKU X 3.5" lift and 35s and pushing around 13 highway on a good day haha but it started out as a 2WD and I'm still running stock gears in the rear so that might be the cause..I should probably regear soon :thinking:
I have a 2008 JKU X with 3.73 gears and an auto, 32" tires a 3.5" lift and average about 12-13 mpg on the freeway and the same in the city and I'm babying it. I think it's my gearing but idk. This is with a bikini top on. I get close to the same with a soft top around 13-14 mpg
2011 JK with 4.10s and manual getting about 17.5 to 18 on 35in Goodyear MTRs at 32psi. I was getting 19.5 to 20 with stock 32in Rubicon BFG mud terrains and high 18s to 19s before I took enough air out to make the Goodyears run flat on the tread. Rolling terrain in SW Ohio.
