On second thought maybe I better see if I can find some time to get you that PCM

Didn't get that diesel toter home? This stinking E10 fuel many stations have around here is killing me with the motorhome. It has an 8.1L gas engine. I have screwed with the PCM until I got it up to 8 to 8.5 mpg towing at 70/75 mph. That E10 crap knocks it back down to 6 or 6.2 mpg. With Jeanie's Lexus it drops from 28 to 26 or 26.5 on E10. That is about 7%, but it's a 25% loss on the motorhome. Went to HRP at Baytown/Houston last weekend (don't ask) and everywhere I stopped in Texas the pumps had a sign saying "this fuel may contain 10% ethanol". From my mileage I'm gussing it all did.
