Responding to the need to run the engine up to temperature after changing the oil, I cannot see any reasonable need to do that. Running the engine and getting the oil up to temperature before pumping it out of the engine will help remove as much condensation and water that may be in the oil as possible and also pick up and suspend any crap that has settled to the bottom of the pan since the last run.
Once the new oil is installed, running the engine for a minute or two will ensure that the various bearing surfaces have the new oil in them for the winter with a minimum of foreign substances such as water present. I see no need to run the engine for any significant length of time or to get the oil up to operating temperature. Also, Ken said earlier "In the spring, I put about a tablespoonful of fresh diesel oil into the air intake and turn the engine over 3 or 4 times without starting it. Can anyone on the list who has more engineering knowledge tell me why this might not be a good idea?" I'm not sure what the diesel fuel in the air intake will do other than upset the air fuel balance needed for combustion. The injectors should be operational and capable of providing enough fuel to start the engine. The idea of turning the engine over a few times without starting it seems like a good one as that will get the lubricating oil into the various bearings before they are put under load for the first time.

I have just been turning the engine over for a minute or less to get the oil circulated.
