Default What's the smoke point of engine oil?

I've been using engine oil as a coolant for high power resistors but
am wondering whether something like peanut, sunflower or avocado oil
would be better. Engine oil gives off an awful smell when it breaks
down, smells like rotten eggs. Can't find transformer oil. Any
thoughts?

Peanut oil is what you want. High smoke
point with a pleasant smell. It's also
far and away the best oil for making
popcorn for the same reason.
