Oil analysis is like the “DEW line” for my engine, seeing changes my eyes cannot. Oil analysis can save you an arm and a leg, and maybe your life. Aircraft maintenance guru Mike Busch, of Savvy Aviation, agrees. “I’m a big believer in oil analysis. We recommend it to our clients,” he told me. He suggested oil analysis should be used like a medical MRI. It’s not the individual scan that’s important but the changes from scan to scan that gives the most relevant information. Oil analysis isn’t an emergency room procedure but a long-term diagnostic tool. So for twenty years I’ve been shipping samples to Fort Wayne and trying to decipher their replies. This time I thought I’d deliver my sample in person, and see what’s going on behind the green curtain.
