I needed to use the JEEP for a few days. Have some towing moving and tugging to do and I broke a caliper bolt on the mouse. SO oppurtunity was knocking. I keept washing gas till I filled the Cherokee's tank. almost 14 freaking gallons Grrrrr :-) took even longer since I discovered the ethanol is VISCIOUS with the plastic that the blue water jugs are made of. Thousands of micro fractions and they chose that day to start leaking. SO I had to pour off the gas as I made it in 3/4 gallon batches.

anyway I put nearly 14 gallons in the jeep till it was full full full - Here are the results!

Keep in mind this was VERY MUCH not ideal. Part of this was 10 minutes at high throttle yanking a stuck van out of some ruts took 4wd and a few yanks :-) Plus 30 minutes idling.

Back at work another hour idling around and using a tow dolly to move some concrete bumpers around and going to fetch a new snow blower (well 46 year old SB) off CL wherein I mounted it TO THE ROOF and this things a beast.

and I STILL managed to beat 21mpg by removing the ethanol from less than 14 gallons of gas and WINTER blend no less.

I don't have time to make another 15+ gallons of eth free gas so I just refilled it with normal wawa regular. I think I burned off enough of the washed gas to not have a phase separation issue with the little bit of water in the 4 gallons left in the tank (I hope :-)

If I drive it enough for another fill we shall see if it goes back down to 17mpg although it does have some eth free gas in the tank so probably not all the way back down :-)

Tomorrow and the next day I need to use the jeep still so I might racked up a few hundred more miles then its back to the mouse. I LOVE my jeep but its just too expensive for a daily driver if I don't need to use it.

FYI this jeep is an 88 Cherokee with 493,000 miles on the clock. No thats not a joke.
