I would have to drain 1/2 cup of crankcase oil after about 10 hours of flight. So I started reducing the amount of 2 cycle oil. I have flow for the last three years mixing 3/4 oz of 2-cycle oil to one gallon (US) of fuel with no apparent ill effects on the engine and I am no longer accumulating 2 cycle oil in the oil pan.

I fly a Zenair Zenith with a cogbelt PSRU and a Warp Drive 3-blades prop and this engine never runs above 5700 rpm When I installed this engine in my Zenith I removed the metering oil pump and have been using two stroke injection oil mixed in the automobile fuel ( 87 octane gasoline) At first I used a volume mix of 128:1 gas to oil and soon noticed an increase of engine lubricating oil volume in the oil pan I have gradually reduced the volume mix of gas to oil to 140:1 but there is still a slight increase of engine lubricating oil in the pan. Also a local mechanic has mentionned that the two stroke injection oil is degrading the 20W-50 engine oil. How much can I reduce the volume mix of gas to oil ?
