I own a flex fuel 2010 Chevy Tahoe. Found a fill station in Canton, Mass with e85. It was priced at $2.40 per gallon where regular unleaded was at $2.79. Anyway, I decided to give it a shot. I had about 1/4th of a tank of regular 87 octane gasoline and filled up on the e85. First thing I noticed while filling was the different smell of the fuel. I then checked the color, looked like a purple color. Put about 100 miles on the truck today (mostly highway) and noticed about 1.5 mile LESS per gallon. Also noticed a different 'running' smell. Not the usual exhaust smell. I really didn't notice any performance related differences/issues. To be honest, with my family in the car on the way to the lake today, I was a bit weary, but I did get here. Anyone else have any experiences with the e85? Negative or positive? Wondering what the oil life difference will be, or plug issues?
