I get about 22 hwy and 16-18 mixed depending on how I drive.

 

14 mpg combined. 245,000 miles with a few issues.

 

I get 12-14 mpg's no matter what. I have a 3 inch lift, running just 30's w/cold air intake and heart-throb exhaust. I am right at 130k miles. I used to get better, even after the size increase in tires... but one day....POOF! something happened. I gotta do something though, b/c the motorcycle will not be option once the temp drops another 30 degrees.

 

Between 15 mpg City & 18-19 mpg Highway. I have a '96 Sport XJ, 4.0L, Auto with 162k miles.

 

could be a bad fuel pump. mine was doing the same thing until i replaced the fuel pump. now I can use 18.5 gallons by the time the fuel light comes on.

 

20-23 city, 27 highway. Healthy 4 banger with a cold air intake and lil' 12-gallon tank, costs me roughly $25 to fill up each time. Does 89 Octane fuel run hotter than 85?

 

93 w/4.0, 33's and stock gearing 10mpg.

 

generally getting around 15mpg mixed, but only had one tank with lift so far. before lift i pulled almost 20 on an all highway tank

 

I dont know if this helps but ive got a '86 MJ 9"s lift 35x12.50x15's 4.56 gears with and ax5 and a 2.5l 4 Cylinder getting about 20mpg highway
