yuck.
I'm just testing ideas. My jeep has been a brute for me for 12yrs.
running Valvoline's maxlife 10w30 for many years.
16 is what I get average with my 2000 with a 2" lift and 30" tires. I've seen 22 highway though. I'd definitely change the O2 sensors and check your alignment too. My friend's Cherokee got much better mpg after his alignment got fixed. It was so bad that the front passenger tire was much more worn than the others.
I'll try to get an alignment done this week. But I know that any pothole will knock it off again.
I, too, have a 2" lift as well, but I have just LT235/75 tires. A lowering kit for the cross-member to keep the driveline vibes down.
thanks for the that advice jeepman.
Yeah my 2" lift made me lose about 1 or 2 mpg. Cherokees aren't aerodynamic to begin with, and lifting them causes mpg losses. It also depends greatly on the roads you drive on. Around town I get 16 average, when I commute to college I drive up lots of hills and take mostly back roads, which decreases my mileage to about 14 mpg. Flat country roads will net about 18 mpg. I've figured all this out using my scan gauge II.
One huge factor in mpg is the ethanol content in gasoline. In CT, most gas stations contain up to 10% ethanol. I have found some non-ethanol gas stations in other states, and when filling up at those stations I averaged up to 4 mpg higher. I've also read some other states mix up to 15% ethanol in the gas. Most stations will list the amount of ethanol on the side of the pump.
