Here in the Heartland we have the choice of 92 oct prem and 89 oct ethanol. I haven't used ethanol in either of my Boxs because of the low oct rating. I have however, used ethanol in other new cars that I've owned without problems. I would not use ethanol in a car that's many yrs old that always used reg gas. I'm not a scientist nor did I stay at a Holiday Inn, but the theory is the alcohol dislodges the gunk at the bottom of your car's tank that reg gas leaves alone. This gunk circulates through your engine and finds the worst place to block (injectors, filters, etc). Don't know if this is true, but my experience has been used cars seem to have more problems with ethanol than new cars that always use ethanol.
