Tony,

What's your style of driving?  Is wheeling included in your 8 mpg's.

Well, in one of my Jeeps incarnations, I was getting around 23-25mpg with all highway driving.  This was a while back when the speed limits were 55mph.  I was running 32's and stock gearing.   The Jeep was only lifted 3" back then too. :lol:

Currently, I'm getting anywhere from 16-18mpg normally.  Although with this last tank, I've had plenty of springs to 4000 rpm so I think I'm around 15-16mph this time.  It's hard to tell since my gas gauge is a bit inaccurate so I have to wait till get to the pump to know how much gas I used.

If I knew why I am only getting 8 MPG I would fix it.  As for my driving style it is a Jeep not a sports car so I do not drive it past the posted speed of 63 MPH (100 KPH).  Lets see what have I done to try to figure it out.  First the Jeep throws a code 51 and I have replace both o2 sensors, plugs, wires, cap, rotor, pulled the throttle body and cleaned it.  And that will erase the code for about 2 hours and it is back.  The plugs do come out black.  The Jeep came with split fire plugs and I just ordered Champion Truck plugs to replace them with and they have been in for less that 15K miles. 

If anyone has suggestions for trouble shooting let me know.

I've got a stock 1994 YJ.  4 cylinder 2.5 MPFI engine, AX-5 manual transmission.  Original 15 inch steel wheels.  No lift of suspension mods.  Gas mileage appears to be slightly better with the hard top in place.  I get right around 22 mpg in mixed suburban driving.
