How long will our glow engines last?? I was talking with a flying buddy the other day and I made the comment that these new CNC machined engines will last darn near forever if run slightly rich and not crashed. I guessed that “darn near forever” would be about 100 gallons of fuel. Of course I am just guessing! I have used many different engines and burned many, many gallons of glow fuel over the years. But I have not kept track of how many gallons went through any particular engine. And yes I have worn out a few engines for whatever reason.

Does anyone have any idea of how many gallons of glow fuel can be burned in a, say, 40 to 90 size glow engine before it is worn out? We must leave out lean runs and crash damage. [sm=50_50.gif]
