Due to my current circumstances, my primary drive to work is about a quarter mile. (Yes, I know, I can walk it). Because the temp is often in the 40s, I will remote start the car and let it run for several minutes, before I drive. Sometimes 3-5 minutes, sometimes it runs the full 10 and then shots off. When I begin driving, I am able to discern, I think, when the thermostat opens up based upon the changes in the heat. I will often drive a mile or so, roundtrip, before going to work, to enjoy the view and to let the motor really warm up. Maybe half the time I do that.
If I recall correctly, some of the BMWs that I had in the past (90s and early 2000s 5s and 7s) did NOT like to have the engines run at idle, for long periods of time (define long?), but I cannot remember why...
Any (informed) thoughts on best practices for this situation?
Also, I am going to be installing the Harrop supercharger in a couple of weeks. It is my understanding that I will always want to make sure the engine and trans are warmed up, before running the engine hard at all. I have no issues with that. I am not necessarily concerned with blowing something out, because I haven't warmed up, because I don't believe I will do that. I am primarily concerned about the general best practices, when I am doing a lot of very short drives.
