COP Oil, Im guessing similar to Trop Artic, Motorcraft, or the other one, uh Kendall. My best guess as a Syn Blend, to be Somewhere in between Motorcraft and Trop Artic.
I've used 76 syn blend oils with good results. It's the same as Trop Arctic that is sold in the midwest. It is a good oil at a good price, I say to use it.
