Engine Heater Worth it?

[Mark_T]

Greetings from just below the Arctic Circle. The block heaters most cars here have are in the 1000W range and are installed in a frost plug hole. Few cars will even start without one at -40 because the oil gets like tar. They absolutely warm the oil, at least to the point where the engine starts freely.

Install an accusump, then you can build oil pressure before even cranking the engine, summer or winter.
