Reply to comment by Illustrious-Fig-516 in 30 minutes of car preheating in sub-zero conditions produces as much particulate emissions as driving 97km in a gasoline car, or 20km in a diesel car “These findings do not suggest to stop preheating cars; instead, we could reduce the emissions by using similar methods that are in place for engine” by giuliomagnifico

You’re going to wreck your engine. Oil is very thick as cold temps and it doesn’t lubricate properly because it can’t be pumped as efficiently. Wait the extra 10-15 minutes unless you like replacing engines.

There is no evidence that driving a car for 10 minutes to finish warming up is more harmful than idling it for the same amount of time.
