I'm thinking of installing an oil pan heater on my car. I had a 125W oil pan heater on a previous car and it didn't perform very well. There wasn't room to install it on the bottom of the pan, so I installed it on the side, and I did not insulate the heater or pan at all.
I'm thinking if I install a heater on my oil pan (preferably a 200W+ magnetic one), and insulate the oil pan all around the heater, that it will perform fairly well.
I guess I'm just looking for ideas on how to best insulate the pan. Here's what my oil pan access looks like:
