Recently an engine rebuilder called with a question I had not heard before. He asked if multigrade oils would increase the possibility of valve sticking in piston aircraft engines. My first response was “why would you think that?” Then I started to think through the mechanics of the problem.
Do multigrade oils increase valve sticking in piston airplane engines?
