Preheat for superior cold air sump.
Hi Mickey:
Tanis Aircraft Products made me a probe that goes in the oil drain hole (where the screen is).
I do know that it is a reduced wattage so that it does not burn the oil, I had to wait for a while for them to develop it. I also have the heating bolts that go on the air intake tubes. This package works very well for me, this is my third winter.
I was working with Dirk Ellis from Tanis, good people.
