there's no special oil for the rb motors. just use the standard or synthetic 10w30 or 5w30, etc, it's personal preferences... if you can spend $ for synthetic, then do so. you may want thicker oil for older engines.
for gear oil, i'm using Redline shockproof. Redline MT90 is good too. a more accessible alternative you can get at the local store is Pennzoil Synchromesh--good stuff...
