Well of course an engine's cooling system must be set up properly. I only cared to indicate that a glow engine converted to gasoline would run hotter and more attention would have to be put into it's proper cooling.

As far as the oil issue, people commonly forget that when going from alcohol to gasoline, the engine will consume around half as much fuel. Half as much fuel also means half as much oil, even if the original oil ratio is applied.
