Just an update on how my block heater is working:

Almost every night since I left Bellingham the night time low temperature has been between -20 and -24 below zero. I check the dash readout before starting the truck and in every case the coolant AND the oil temperatures have been at 104 deg F.

I didnt expect it to keep the engine oil warm and I am not sure how it is doing it whether it is through the oil cooler or some other means but I am pleased with it's performance for sure. And it makes atarting a breeze in really cold weather. I have only cycled the glow plugs once as I would at any time before starting.

Thanks for the update. The oil temperature sensor is probably on, or near, the block and the oil in the pan is still cold, but as it is pumped thru the very small clearances in the engine it will instantly pick up the heat from the metal parts. The oil pump can push cold oil thru those clearances more readily if the oil already there is not extremely cold.
