To protect the vehicle from cold

I have 206+ vehicles, I have been using it in Erzurum for 2-3 years, the tool did not only work for 1 day, it came to -40 at night, all the vehicles did not work, we did it with reinforcement. and the vehicle passes from gasoline to tube for 10 minutes, can it have negative consequences if we store it with any blanket or hood inside the hood in order to protect the engine?

Even if you put it in the garage, it doesn't matter, because the screen is dim and the battery is weak.

It's true what your friend says. But in order to keep the engine warm, when I was working in a place with a minus 42, I would start the car and put a blanket in the hood. I would put the carpet (savanna) first, to cover the top of the hood and the windshield. It is important to note that the blanket is too hot to ignite the engine. I spent three winters like this. He did not work only once, so the vehicle had been lying down for three days. I did not run it, we did it with reinforcement

The most important point to be aware of when I know my master blanket or something is the oil selection.
