This don’t warm your car up thing comes up every year. One year I tried to go deep down the rabbit hole to see if I could find any actual data. I found countless articles that referred to other articles and eventually I found a few that referred to a report published by “automotive consultant” Based out of Northern Virginia where one person said, who is supposedly an expert in automobiles, that warming up was not required. All these articles seem to refer to this person, and I could find no study or actual data. If anyone knows of such information please point me in the right direction.
This is yet one step further. Making the argument that you don’t need to warm your car up is one thing. Saying that idling actually hurts your car, with a closed loop controlled engine Is to me utter nonsense.
