When a gasoline or diesel engine develops an unexpected problem, it leaves the owner stranded at the side of the road. When an aircraft engine develops an unexpected problem, it can have far more serious consequences.
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.

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?
