Starting Over

I got my best mileage yesterday with 87 octane 100% gas and it was a whopping 13.5, according to the computer which has been pretty close. This was about 100 miles of highway driving at about 70 mph... Before that with 89 octane ethanol blend I was getting about 11 mpg with mixed driving. I think the big change was due to the 100% non-ethanol gas.

Yeah, I ran ethanol free gas whenever i could in my other truck. it did make a difference. you could tell a pretty fair difference from 87 w/ ethanol to ethanol free 91.
