They put it in plastic bottles now. Used to be in tin cans, like pint/quart booze flasks. I liked the tin cans better.
It's amazing this stuff is still around and is still being advertised as a 'top end lube' for automobile engines. One thing we were taught back in the 60's, was never put Marvel Mystery Oil or STP in your engine. All they did was change the weight. STP turned 30 wt oil into 40 wt. Marvel was the opposite; 30 wt turned into 20 wt.
But at least STP is useful for case lube.
