was getting 18mpg city/hiway..added the 305/17 bfg 's and mpg went down to 16.7 @ 32 psi. was at 28 psi but mileage and power was terrible altho ride was great If I go up in pressure mileage will increase but ride will suffer.

 

After having the fuel injector replaced, I'm getting 20mpg (per dash mpg readout) with 80% city 20% hwy driving. I was only getting about 17 before that.

 

Can you elaborate on this? How did you end up getting your fuel injector replaced? Did you just tell the dealer you didn't like your mileage, or were there other problems occurring that led them to replace it?

I'm getting 10mpg city and 14mpg hwy with the 2.5 tera BB, 32" tires and a heavy foot.

 

Jk Unlimited Sahara- Auto, 4.10 gears, and Rubi rims/tires. Getting on average (50/50 city to hwy) about 18 mpg. Not to heavy with the foot, but no granny driving either. Oh ya this has had the flash done.

 

Went to start the JK a couple weekends ago and the engine was chugging like an old diesel engine (who needs a CRD!) and white smoke was pouring out the tailpipe. I took it in and after waiting about 3 hours at the dealer, I was told that the fuel injector was bad and needed to be replaced. 3 days later my JK was better than new.

 

WOW - that is TERRIBLE mileage... I won't complain about my 16.5 mpg average in mixed driving anymore!
