Commercial for STP Oil Treatment; a man rides his dirtbike hard through rough terrain, then stops next to his truck; “Hi gang! No, this ain’t a beer; it’s STP Oil Treatment. I take care of my own cars and have been using STP for the last ten years. The troops at STP tell me it makes the oil tougher--even a premium 10W40. It helps reduce engine wear and burn less oil. What I’m telling you is it works, and you can take that to the bank!’
