I have been consistently getting over 20MPG! Pretty surprising, considering even when the Jeep was smaller I would get about this ... when I installed the Grand Cherokee fan clutch it dropped to 14.

Just filled up today and got 20. Unfortunately, it was at a different pump that didn't click off. It spilled out a bit and the gas gauge is pegged about 1/4 tank past full. Would have been a bit over 20 had I went to the normal place I go.

I am trying to see what happens if I go to ethanol free 93 again.

The last tank of gas I finally managed to figure out the driveline vibrations. To test, I took the Jeep to help a friend with his Jeep and ran about 70 miles on the highway at 70MPH. I don't think getting 20 for the tank was bad considering it's a tractor engine propelling a lifted brick down the highway!

I would like to do the injector swap and replace 02 sensors.
