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.

"Made from petroleum oil" can mean that the synthetic oil is based on
chemicals originally derived from petroleum, such as ethylene and its
relatives. Plastics are also "made from petroleum".
