How to Make Your Engine Last

Whether you operate on the rich or lean side of peak EGT, make sure you understand proper leaning technique. And know this: If you want to fly fast, you must operate rich of peak; lean of peak is for economy only. Jon Whittle

Key Takeaways:

  • Strictly adhere to manufacturer recommendations for engine maintenance and operation, rather than relying on informal advice from "experts" in forums or coffee shops.
  • Ensure engines are run regularly and hard (e.g., in the 75% power range for new engines), as prolonged inactivity or consistent low-power operation can lead to corrosion, cylinder glazing, and other damage.
  • Perform critical maintenance, including routine fuel system calibration, informed mixture leaning (ROP/LOP) with proper monitoring tools, regular oil changes, and inspections of magnetos and gauges, to prevent component wear and catch issues early.

If you want to ensure your engine has the best chances of reaching TBO and beyond, here’s advice that could end up saving you big time: Stop listening to all the supposed “experts” in airport coffee shops and online forums who claim they know it all. There’s a good chance they don’t — and the wisdom they spout could be the polar opposite of how you should be caring for one of your biggest aviation-related investments and the one piece of equipment you literally can’t afford to have fail at the wrong time.
