Hey guys
E85 is 102 octane and is 85% ethanol and 15% gas...
Make sure to keep rubber fuel lines to a minimum and check often. If your running braided lines its a good idea to check them once in a while. Cant hurt!
Because I live in CA and E85 hasnt made it to to many stations, Im in the process of building my own still to brew my own ethanol. I have the permit and plans and some of the materials for the Charles 803 still.
Here is a the site for the still and alot of Ethanol info.
Make your own Fuel
cheers
Charlie
