block heater or no block heater

[original]

Looks like were in the same general area. I use a simple dipstick heater that works wonders. On many occasions, without the heater, the truck has failed to start at temps below 40.

Why so dead set against magnetic pan mount type? My O9 came from UT. and that's what National Guard put on it. Just asking... When they die will it potentially damage power pack/vehicle. Such as catch on fire or something?

Pretty rare that we get into teens here in California! It does happen though. What is our threshold 30, 20, 10 for preheat?????

Curious about the magnet heater as well

Some oil pan heaters put out too much heat, and cook the oil. Cooked oil isn't a good thing.
