Steve Bennett was using NAPA semi-synthetic in my engine when I bought it (and Ken Cottle's plane) from him in 2006. I've stuck with what Steve was using and almost always use avgas instead of car gas. I've had no issues. When I put new valves in I was amazed to find my guides were like new, despite the lousy job Rimco had done in re-using valve springs, etc. Anyway . . . just my experience. I like the semi-synthetic because of its ability to withstand higher temperatures without breaking down. On those climb-outs in the middle of summer in Kansas the engine needs all the cooling help it can get.
