I'm trying to determine realistic MPG with a 4.0/AW4 running 33x12.5 and 4.56 gearing. This combo is actually in a CJ but since this came from an XJ I thought it would be best to check here. My son has been complaining about poor gas mileage (10-12) but I'm trying to see if anything can be done to get this to 15+mpg. Other than a basic tune up what else can be checked? I did just replace the O2 sensor (no codes but read about lazy sensors) so hopefully that will help.
Thanks in advance for any input.
