Thanks for the input. The Aero Shell 15-50W seems to be doing a good job for me. I have had to replace 2 cylinders in the past 4 years for low compression, which is no fault of the oil. Just wanted to here what you folks think about straight weight oil.
Had to change both cylinders because of leakage in exhaust, the first was due to a crack in the cylinder. Still waiting for hangar space to change the current cylinder. Don't know if this one is due to exhaust valve or a crack like the previous cylinder.
Still hoping to fly by Jan 1 2015
