Jeff:

Ethanol (grain alcohol) will not ignite with glow plug ignition, but when the methanol ignites the ethanol should burn happily. The ketone shouldn't have any effect.

The only problem I see is the possibility of the ethanol diluting the methanol to the point it wont fire.

But how much can your hardware store methanol cost? Buy a quart, mix it with eight ounces of castor oil and try it.

Let us know how it works.

Bill.
