Got a deutz with an oil pan heater and its not that great. I have seen some like the stick on ones on small aircraft motors that seem to work ok. They only have a gallon or gallon and a half of oil to heat. I would need a really big one to heat up the 5 gallons of oil in this motor in a reasonable amount of time like 1 hour. It should be easy to install though.This engine will start at 10 degrees F no problem but I dont like starting an engine when its that cold without heat. I try to plug them in below freezing for better engine life.
