well, (pardon me in advance), the glow engines already run on methanol and oil. But, if mentioned in your post that the methanol is the same used in vehicles, i really don´t know. I think that the fuel wich runs on surface is a little bit different from the fuel that flies. In Brazil we don´t use methanol in vehicles, just E85. So in this case, my post doesn´t help at all.

best regards.
