Nothing wrong with PoCo oil. They havent used PCBs in years. We use
the same stuff at work made by Shell . Its just mineral oil with a few
additives.

That's good to know.

I have a 200 watt air cooled dummy load made of 2 watt resistors. I
was curious as to how much power it could safley disipate if placed in
a gallon container of mineral oil. It seems to handle 200 watts
continuously with just a muffin fan on it.
