I like the Golden Shell, Archer, And Pennsylvania Oils. Those are what I's run if we were back in the days of SA oils. Speaking of which, a few years back I visited a machine shop which was owned by and older guy. He certainly had money judging by his new house and new cars. The unique thing about this guy is he also liked to buy and collect useless things. He called me over to a tractor trailer and he said " I bet you've never seen this". He lifted the door and inside from front to back floor to roof were were metal cans of old Quaker State motor oil. I didn't know what to say or ask him what he was going to do with it all.
