I am no race guy so I ran E85 in a four stroke with good results, but it was in a race motor? lol
I am also not a fuel expert & E85 might not be for your setup, but I do know you should match the fuel to the motor. Even certain race gases will do more harm than good in a stock motor.
So I would like to try & state the truth, all facts? Correct em if I am wrong cause thats possible? lol
Not all alcohol is the same different forms react different & have differnt properties. Methyl Ethyl Butyl I believe are the 3 main forms.
Alcohols, when used near their stoichiometric air-fuel ratios, produce more power, a larger quantity of fuel is required to produce a specified power output. For example, in an automobile, more fuel is required for each mile driven.
Oxygenated fuels (alcohol) considered race or not will need bigger jets, since the fuel contains oxygen. needing more fuel to offset fuel containing O2.
Most forms burn cleaner, less carbon
alcohol burns slower so advanced ignition is important for a complete burn? In the motor it will have a longer burn, which will usually produce a stronger midrange
Higher compression also helps take advantage of the fuel properties?
Generally, methyl alcohol is the most corrosive and butyl alcohol is least corrosive. Methanol is corrosive & you should flush your fuel system correct?
Alcohol will absorb water hence why it is used as an gas line antifreeze. This is good in most cases & in stock motors. May be a issue if you allow it to come into contact with moisture, but moisture not good for any fuel?
Aviation fuel octane is rated different so it would have a lower rating if tested the same as pump gas.
Also anyone running a alcohol in a 2 stroke/premix during cold weather should run a Castor oil as to avoid oil gas separation?
