Earl,


Somehow, gas engines need much less oil percentage-wise, compared to glow engines; despite using about 40% as much fuel when running.

For this engine, which has a bushed con-rod, 4-5% is right, compared to 17-20% for glow engines. That is about one tenth of the oil; and had it been a needle-bearing con-rod, 1/20 the amount of oil would easily be sufficient.

I guess it is the way oil mixes with the different fuels. It actually dissolves in gasoline, while in methanol it is a suspension rather than a solution.

On the APC 11x8 you got 0.92 HP...
