ok really quik ther e85 is obviously 85% ethonal first the unless u nuy the motor from the dealer and it a flexfuel (i knowiknow thats chevy) or e85 campatable should u think about using this fuel. here are two reasons first unless u change out the seals any rudder parts coming in to contact wioth the fuel will decay much faster than normal second it wont give u more horsepower alcohal only has a fraction of the amount of energy per gallon as regular gasoline hope this helps
