Thats funny, Ive run Mobil 1 in my 901 for years. My cars are track use only and only see a few thousand miles a year. They dont see day to day use like a street car might, but they shift fine for me.

Do the sintered bronze syncros work better with dyno rather than synth?... maybe in small increments..

Ive used swepco,amsoil, Mobil 1, and other gear oils. Im having a hard time believing one is a magic elixir.

but thats me always doubting
