I just found a local source for SWEPCO products. I've been running the 201 gear oil in my Datsun's transmission for years with very good results. I'd love to run the 201 gear oil in my M3, but the book calls for a GL4 rather than a GL5. I've heard that people run GL5 Redline shockproof in their boxes but I don't know if that is such a good idea since the sulfur in a GL5 will attack brass syncros.
SWEPCO also offers a 20/50 motor oil with really high zddp (14000+) that sounds like a winner as well.
I'd love to hear your guy's thoughts.
