Our club 182H is an annual inspection now. I stopped in just to see how it was doing. They said everything was going well but they noticed The spark plugs on the left cylinders (O-470) had oil on them. The compressions were all good. We recently did change oil to Aero shell 100 at the last oil change. The engine doesn’t really consume a lot of oil in fact during the summer run it consume less than I thought was usual. The mechanic said he didn’t really have a lot of concerns about it and that he was in a get everything changed and run it for a few hours and re-check the compressions. The engine only has about 300 hours on it. I admit I am out of my league when it’s talking about these things however it certainly sounded concerning to me?
