"Already have a pre-oiler on my car for full oil pressure
before turning the starter, since according to McDonnell-Douglas, Continental, the SAE 80-90% of all engine wear occurs during the first moments of start up after an engine's been sitting more than a few days, or a week, let alone a month or more."

I doubt that to be the FULL description of ALL the facts.

Greatest engine wear is due to placing demand on the engine BEFORE it reaches some 60%-70% of operating temperature. Especialy HEAVY demand. ESPECIALY in cold weather. Constant and significant heating and cooling cycles between start up's (even if it's multiple times per day every day) is just as bad for wear if operating temperature is not attained before placing demand on the engine any more than just idling to warm up.

Does Mcdonnel DOuglas and Cont run preoilers on their engines that do NOT HEAT the oil ??? Probably oil or block heaters only for the purpose of keeping the engine warm and not for sole purpose of oil circulation.
