I've used Redline MTL and Mobil 1 Synthetic gear oil... all worked better than conventional gear lube for smoother shifting.  :thumbs:

For break in period, just run conventional 75w90 oil.  Your going to drain it out after 1000 miles so dont waste money on expensive synthetic.  After break in spend the money on the good stuff, Myself and many others at the shop here use Redline MT90.  90 weight, great synthetic oil, and it has a additive to help protect and preserve brass, so its good for the synchros.
