This is getting better than any oil thread around....
I would still be interested to see some research on the effects on vehicle mileage and wear going from 0% ethanol to 10% and from 0% ethanol to 15%. Perhaps our august research firm has some data on these?
Btw, I paid my way through grad school in the mid 1990's hauling fuel in tank trucks. Most fuels even back then had up to 5.7% ethanol blened in at the loading rack to enhance the octane.
Experience is what you get when you don't get what you want.
I use the pure gas site. A 2010 Camery will get about 36 mpg with non alohal will get up to 43mpg, this is not a hypride .
