mpg


Not me. I don't have a lot of faith in the tuning chips (just opinion, no research).

what type of mileage are you getting?
 
Non of the chips out there work with Jeep. Some end up causing issues.


To increase mpg there are basic things. First be sure the engine is running properly. Clean air cleaner and TB, proper spark plugs gapped correctly, clean injectors, clean valves. Aligned with proper tire pressure. Charged battery with all clean connections.

Light on he skinny pedal and don't rocket launch.

There are no cheap mpg improvements. Increase compression ratio, and add a turbo or supercharger.

Also drop your top speed by 5 or 10mph, you'd be amazed at how much fuel you will save. Make sure your speedo is reading accurate for your mileage calculations.

And remember, it's a Jeep (brick), not a prius. But I get wanting to get the most out of your vehicle.
 

thanks, you're right. I knew mpg's were a point to think about, i'm not going to mess with something so good. love my jeep, even at 18mpg.

If you are getting 18 mpg you are doing great! Most are reporting 14 to 17 mpg

Yeah, I'd be thrilled with 18. I always got 14-15 in my TJ and my JK is getting the same. I'm worse case scenario though as I drive very little hwy and only work 4 miles from home. Lots of short trips.
 
18??? man, i would love 18. sometimes i get 8

the wife's 07 gets decent mileage though, hers does get 15 in town and 19-20 on the highway
 
I have a 95 wrangler with the 2.5l and gettin 17 mpg at 144,000 mi but my buddys got a 97 with a new hart (same motor) and gettin 25 mpg
