Oil additives

There are only a few things I will add to oil now, then most of the time change the oil 30 minutes later(Stuff that's an old trick). That video really shows the science and I now don't trust the oil additives more than ever. When I was younger we would have the BG guy come and restock the shelves with their snake oil oil additives, but the more we used that crap and the others too, the more I noticed they did not make things any better. It was all marketing BS that even fooled the repair shops into stocking it to sell it to their customers.
