Perhaps with your extensive and pontifical experience you cold summarize the findings of Shell, Chevron, and TCM of the percentage of wear that occurs in the first 30 seconds of cold (ie, below 40 degrees) starts?

May I humbly pontificate that proper starting of engines (incorporating the, appropriate for the temps and engine, oil) at 25F will NOT impact their respective TBOs to any statistically significant degree. I have many examples of this at the airports where I have been based and I follow this practice on my own plane.

Well, your holiness, no one said anything about TBO. I have many examples of this at the airports where I have been based and I follow this practice on my own plane. Since you blew in with your qualifications at the forefront, answer the question and don't change the subject and go off on tangents (like TBO). Also, see the references in my later reply to Peter R., and be aware that anecdotal stories are pretty much useless.

Well, your holiness, no one said anything about TBO. I see what you mean. I intended to convey the idea that no damage would occur to the engine resulting from the cold-ish starts within the time period to overhaul. Do find some inner peace, my son ;-)) (the holy-ness kicking in).

He never said anything about "killing" his engine. He is certainly worrying more than necessary, but that is no worse than your overly melodramatic and condescending response. Actually, your response was worse as his was made from ignorance and yours was intentional. Matt

Preheating engines: Airplane engines versus auto engines
Isn't some of the problem with cold starts not necessarily oil related but
related to piston scuffing against the cylinder walls? The aluminum pistons have a greater coefficient of expansion than the steel cylinders and the pistons should become a looser fit at colder temps. I'm not sure how the rings fit into the temperature equation. -- Best Regards, Mike http://photoshow.comcast.net/mikenoel "gpaleo" wrote in message news:1198154485.901022@athprx03...
