I have seen several, here and there posts. Since this forum seems to be so popular with large threads I thought I would try and start one.

Post your:

Tire Size
Gear Ratio
Transmission (Auto/Manual)
Fuel Octane
Chipped/Programmer/Flashed
Driving Style
RPM's @ 70 mph

Comments, if any.

Comments, if any. Why in the world do I get such crappy mileage with stock tires?
everything's the same for me except no programmer and you have a lift and a 4 door. i was averaging 16ish on the highway from knoxville to memphis (~400 miles).

Mileage Dash Computer/Divided by gallons at the pump - Nothing so fancy as that here, this is a Jeep son. lol No seriously I calculated by dividing number of miles driven since last fillup by number of gallons pumped. I'm averaging just over 17 mpg


Tire Size - 225 75/ 16


Gear Ratio - Don't know, whatever is used in a stock base model X. I think it's 3.73, but not sure.

Transmission - Automatic

Fuel Octane - 87


Chipped/Programmer/Flashed - nope, stock


Driving Style - Life is good, take your time and enjoy the ride

RPM's @ 70 mph - Just a shade over 2000

I see that automatics have a higher last gear then the standards. Its weird but the auto may get better mpg on the highway. Most vechicles post better mpg with the standard trans.

Possibly true, if you can stay out of the throttle with the auto it might yield better MPG's. With the manual you still have more control over shift points so that is a plus. Autos also generally suffer from more parasitic loss in the drivetrain to.
