I've been running Royal Purple on my SR for 7 years. Took apart the motor for my build (it was still running perfectly) and you could not tell the motor had 200k on it at all. The bearings looked awesome. RP has the highest film strength of any other oil that I've researched, which is why I originally went with them. The down side is that it's expensive, but at least you can get it virtually anywhere. That's their motor oil, their gear oil isn't anything special. I use Torco for gear oil.
