Okay, I don't want this to be another "why doesn't my JK get as good gas milage as my wife's prius". I get 10 mpgs and I just want to get a few more, I was reading a lot of members get better milage with the same set up I'm running. I'm driving 70% city 30% highway.

Any suggestions, besides the whole "get another vehicle" comments?

 

Did u get a programmer to adjust your speedo?

 

I have not done that

 

Then you are probably getting 1.5-2.5 mpg's better than what the jeep is reporting.

With an auto, recalibrating will also correct the shift points.

Other than that, regear.

 

Then how are you calculating 10mph? With out the tire size and spedo being calculated correctly you are not accurately counting the number of miles being driven.

 

Get superchips or similar. It's almost a must

 

Since its an auto at the very least get an aev procal $150, this will adjust your shift points to make up for the larger tires and adjust the speedo, you should see a couple more mpgs

 

You need a programmer to get your speedo and odometer correct. It will also correct your shift points and help you regain some efficiency. You can't properly measure mileage when you don't have good data to calculate from.

You're also under geared which will rob you of efficiency. You're vehicle is trying to move under acceleration before you even get past the stall speed of the Torque converter. Roll out slower from standing starts and turn OD off for highway cruise speeds of 65mph or more. That'll stop the gear hunting on mild grades which is creaming your efficiency.

 

True. And also the performance tunes can help bring back some of the lost power

 

Procal worked out great and its super easy to use.
