A further report on the Redline 80W250 bevel box oil after 2000 miles run to Switzerland and back. My conclusion is that it isn't the cure for a screeching M3W BB that was hoped for. In fact it may even be slightly noisier than the Redline Heavy ShockProof (pink) oil, once the bevel box is fully warmed up from a few miles of motorway driving. Not saying don't use it but it's not a cure for noisy bevel boxes.
