our cars from factory can handle up to 10% ethanol, no more. reason for that is because the ethanol will slowly eat away at the factory lines/injectors since they were never designed for higher concentrations.

sambls100 where do you get pure premium? I thought there was a government mandate that all fuel had to have some alcohol? (that dam Al Gore is messing with my gas mileage and power he should be shot)
