Previously, if such a question appeared, the answer would be unambiguous: of course, warm up! But today it is 2021, completely different technologies and other machines. Open the manual of a modern car: in most documents you can probably find recommendations not to let the engine idle for a long time. It is advised to warm up the engine "on the go".
Here are the arguments: harm to the environment, excessive fuel consumption, slow oil heating, the formation of soot on candles and the appearance of unburned fuel in the catalyst. In some EU countries, it is expressly forbidden to stay in the parking lot for a long time with the engine running. Everything seems to be clear - no need to heat!
But there is another "side of the coin". An increase in the number of revolutions of a cold engine dramatically accelerates the wear of components, which is associated with oil starvation and thermal expansion of parts. All this reduces the resource of the power unit. Obviously, the truth is somewhere in the middle. On the Repeat AutoHack channel, the author clearly tells how to warm up the engine so as not to harm the car. And the environment, of course.
