Warmer and oil that sounds pretty dangerous is the car outside? Or in a garage

^^ If I had a garage it would be inside of it
An oil pad heater is something you glue on the bottom of the oil pan , not dangerous at all .

I like that oil heat pad idea.

Here in Minnestoa Its going to be -25 below over the weekend not including windchills and thats just narly cold. I cant imagine -40 below
