85% ethanol, 15 % gasoline. 100 + octane. Works great with 11:1 + compression ratio engines. Burns very clean. Money spent at the pumps would go to American farmers, not overseas.
Sounds good!! And it is fully compatible with our current engines?
Longer-term use of E85 in gasoline-only vehicles may cause damage because of the incompatibility of the alcohol fuel with the parts in gasoline-only engines. Performance and emissions will also be compromised.
I've also read that even though the octane ratings are up there, the btu's that ethanol is capable of producing is not the same as 100% gasoline. Meaning that it doesn't produce the same type of explosion and therefore less power. I'm no engineer so please don't ask me to explain this. Just passing along info.
short version for those of you that refuse to read, alcohol has a much higher octane rateing but a lower btu level that means it will produce more power than gas but it requires quite a bit more fuel volume per mile traveled, or put another way you can have your 500 plus hp and your clean air but your going to get lousy mileage and might have corrosion problems because alcohol is hygroscopic (absorbs moisture from the air)
