Hey guys, I am a newb around here. Just bought my first Jeep a couple of months ago. It is a 2012 Sahara, 4D, lifted (I think 2.5") with 35" Mud Grapplers and auto transmission. I drive ALL pavement. The other day, I was playing around with the instrument panel and saw that it auto calculates MPG. I was astonished to see is was at 9.6MPG. I reset it and ran through a tank of gas to find I was at 10.4. The next tank of gas got 11.1. I've done this a handful of times and been between 10-12 MPG. I certainly was not buying this toy for the mileage, and I knew the lift/tire combo would have some impact on MPG, but certainly had not expected this performance.
I read some previous posts about gear ratio making a big difference in mileage. I do not know what gear ratio I have as jeep's website does not have the window sticker for mine.
Is this likely a gear issue? If so, what options do I have to improve some gas mileage.
Thanks in advance.
