What is the lifespan of a Lycoming engine?
Lifespan and TBO: How Long Will Each Engine Last? Both rebuilt and overhauled engines are designed to reach their published TBO. For most Lycoming four-cylinder engines, that’s 2,000 hours. For some six-cylinder models, it can be 1,800 or 2,000 hours. Gasoline engines: Around 1,500 hours or more is typically considered high. With proper care and maintenance, many gas engines can last between 1,500 to 2,000 hours. Diesel engines: These engines are generally more durable, and 3,000 to 5,000 hours or more might be considered high.Most car engines can last up to 300,000 miles or more, with properly maintained ones lasting a lifetime. However, factors like driving habits could shorten an engine’s lifespan, as they could accumulate wear and damage.
