I dont think of this as a debate, just facts. I ordered cases of the Brad Penn stuff last week. Any oil will work, some are better than others. Navarro put a lot of work into his research and works with air cooled Porsche engines.
Royal Purple would be the oil I would use if I didn't go with the Brad Penn stuff, as it comes with high recommendations also.

I use Amzoil in the tranny
