Oil analysis is a critical component of aircraft maintenance. It's just one tool in your bag of tricks to keep your engine running in top shape. Air-cooled aircraft engines are twitchy, heat-sensitive machines that vary widely in wear depending on the type of aircraft they are installed on, the type of cylinders installed, and how they are operated.

Aircraft engines and repairs cost thousands of dollars. When you invest in a new engine or an overhaul, you want to make sure tolerances are set correctly and the engine parts are working well together – not only to get the most time and enjoyment possible out of your investment, but to literally protect your life. You've checked the weather, filed a flight plan, and done a thorough walk-around. But if you haven't checked your oil in the last 50 hours, are you sure you're ready to take off?
