I'm now a guy with a compressor

They say to use compressor oil, but you are smarter than the people that designed it?

Whoa, what's YOUR deal? The owner's manual clearly says:

"USE SAE30 INDUSTRIAL GRADE AIR COMPRESSOR OIL OR FULL SYNTHETIC MOTOR OIL LIKE MOBIL 1 10W30. DO NOT USE REGULAR AUTOMOTIVE OIL."
I'm using Mobil 1 10w30.

Look it up.
