i own a mazda protege 5 2002...i am a new driver and recently i have noticed a sign at all gas stations that the gas contains sometimes up to 10% ethanol...this isnt making me happy...my motor was not made to run off this crap and slowly but surely will make the life of it shorter. I would like to hear some opinions on ethanol cuz as of right now the only person i know who supports it is obama haha...i think it is the biggest waste ever
