I was looking at these external oil preheaters. i was wondering if anybody ever used one of them. My use for it would be to preheat the oil in my engine before i start it in this below freezing weather. I have 20w-50 oil in it from summer and racing and i havent started it in a while because the oil is too thick on start up. Im thinking this will thing it out. Iv been to busy to change the oil and see this may work. Car has a blown transmission so i cant drive it but id like to start it once a week or so just to keep the juices flowing. Here is what im talking about for reference. thanks for any help
