Hi Corky,

Even John Deakin burned out a set of
Continental cylinders in 500 hours LOP in his Bonanza. And their
highly
touted fuel savings are, for the most part, due to a decrease in
speed. You
know, all that drag increase with V squared.

I'd hesitate to speak for Mr. Deakin but I'd venture that he'd
disagree violently that running lean of peak burned out his
cylinders.

Even if it did - Mr. Deakin is one of the key people in developing LOP
operations for today's GA Piston Aircraft. I guess he did experiment a
bit with it before getting it right.

However I fully agree: If done right running LOP puts less (thermal)
stress on the engine and is certainly not going to "burn out"
cylinders.

regards,
Friedrich
