Dummy load fluid

Can be found on the same aisle as the muffler bearings just below the shelf which stocks the all the cordless extension cords!

A T F works just as good For a lot less &&&&
I'm just about to build an oil-cooled dummy load by inserting an air-cooled one with two parallel 100ohm Carborundum resistors in a frame, into a stainless pot and filling it with ATF. I'll not be running any more than 100W into it, for now, until I get something more powerful to try out.
I'll let you all know if I burn my house down. :)
Digging around, there seem to be plenty of people who've run ATF-filled dummy loads for years, with no downside.

Food grade mineral oil is what i went with mostly because of the covid shut downs at the time.
The mineral oil is really a better choice to atf should you have an issue or need to service. Also be sure the manufacturer says the resistors are ok to be immersed in a petroleum based oil.
 
The MSDS shows it's pretty inert

I'm remembering a movie called "Private Benjamin". Her army basic training company was going to crawl through a minefield, and the drill sergeant announced that "Most of the mines are inert. However, some are ert." Thought I was gonna die laughing at that one.
