I found some really cool 80`s Pennzoil oil ads on Ebay:






Johnny said:The GT 25W-50 Racing Oil has been out for years (at least since 1988) and it is API SL. Last I checked the zinc content was somewhere between 1200-1500 ppm. Before everyone started using synthetic oils it was the most popular oil to use in the World of Outlaws and there are still a few that use it. Also works great with cars using alcohol, methanol, and nitromethane fuels. When I lived in Texas I use to sell a boatload of it to the local H E L L S ANGEL chapter for their Harley's.
Still a very popular oil with Central PA 410 Sprints. The PA Posse sent the World of Oulaws packing 2 weeks ago.
