dont even waste your time, its not worth it, and E85 is NOT the fuel of the future, its just not cost effective, the reason its gotten a push as of late is the corn lobby in the legislative branch.
While its not the fuel of the future its the fuel of right now and I'd rather spend my money here than send it overseas. Less mpg, slightly lower cost, a few mods to my car, its worth it IMO, I hate being so dependant on other countries for oil. Even tho we still will be, Ill know where my money would go to.
