Options for reducing engine RPM's

[jared]

**small thread hijack**

 

FWIW, I'm a new TJ owner...bone stock 2.5L with 4.10's, 31's and an AX5. I'm a bit surprised at just how crappy these things are on mileage. I wasn't expecting too much, coming from a DD car that got 35-40 mpg, but it's only averaging about 17-18 (filling up consistently around 1/4 tank and 225-240 miles, it's been taking 13.5 gallons or so). I know it's like driving a toaster on wheels, but honestly was expecting about 20. I'm not crazy with the pedal, either. Were 31's stock on these things? I've got aftermarket aluminum wheels on it, and am thinking maybe the PO swapped tire sizes but didn't change the speedo gear (???)

 

So far, I've changed the oil, tranny and TC fluids, cap, rotor, wires and plugs. Gonna do the diffs and give it a coolant flush, then everything will be new once again.

 

....now back to your regularly scheduled thread....thanks :D

18 is pretty good actually. my tj witht the 2.4 gets about that. the most i got was driving from michigan to new jersey drafting behind semis going about 80 mph. i got about 23 mpg the whole trip.
