Go ahead and laugh but, since we don't have many days here that are so cold you need to preheat the
oil, I have an old electric blanket that I wrap around the
oil pan and up the sides of the motor. Then I just plug it in. I have only used it three times when it was extra cold and I wanted to start the car but it did a fair job, and when it stops working I will pull the heating elements out of it and use it as a mat or floor cover to lay on. I also have one of the outside of the pan heaters that you just stick on the bottom of the pan. I don't glue mine on as I so seldom use it but put it on with a small piece of tape on each corner and that peels right off when I am done.
Edit: Just so you understand, I don't drive my car when it is that cold. But after it sets for a fewweeks I like to start it and run it until the temperatures are up to normal. Anything below 70 degrees is to cold to drive in.
