Swepco is good too, but the hype it got in years gone by makes me laugh. It is very good gear oil for your application though.

Sweet thanks Jeff. I needed a nod of approval. The BP stuff is 80w90 GL-5 and covers a LSD. seems perfect.

I cannot get over how fun a 915 is to drive at the track. I've got 3300 track kms on the box since I've owned it. Mated to a 3.6 with 270 wheel hp. I hope I can get another 3,000+ track kms out of it. Keeps you honest for sure but that is why its so good.
