I am not too sure about that statement. Does that include silicon oil?

I don't know, but I doubt it. Silicone is a whole other kettle of
fish. I was speaking of motor oils.

And how about the oil for use with 410a refrigerant? And then there is the oil with iodine in it. And the transmission oil made with jojoba oil.

Again, I was speaking of motor oils.
