i think the best thing you can argue is the fact that alot of people get ethanol mixed up with methanol

methanol being highly corrosive.

also there is around 10-15 % ethonal in normal gas, and there has been debates for a while about raising the ethanol content of regular gas to as high as 50%

Since 1977 the government made mandatory to blend 20% of ethanol (E20) with gasoline


as somone stated before the bigger injectors and fuel pump is to account for the added 30% usage


you also need some kind of tuner, for one to account for the 30% and also to account for the different burning caracteristics of e-85.

e-85 burns more efficiantly and cleaner.

another thing to note is lean / rich mixtures of either fuel. stoic (ideal) afr's for gas is 14.7 and for e-85 is around 9


as well if you look at octane ratings, the highest you can normaly get at a pump is 93, thus limiting boost or compression depending on application.

where e-85 is normaly around 105-110 helping prevent detonation at higher boost levels or higher compression levels
