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 ? Please advise Yvon
