Default XJ Gas Mileage

Hello All!!!

I tried searching through the forum, but as a new person I couldn't figure out how to get the search funtion to work.

Regardless, I was wondering if there was anything I could do to improve my gas mileage?

Thanks,
JW

buy a civic?


just kidding. The best way to improve it is to save all the money you would do on mods and just put it in you gas tank. Or just adjust your driving style to be a little more gentle.

If you did want to do a mod, I hear that a bored-out throttle body is about the only thing that would help.

Best thing I've ever done to improve MPGs was get a nice O2 sensor

I got the "Premium Bosch Oxygen Sensor" from Advanced. Better mileage and runs quite a bit better now.
