Here are oil options rated (in my opinion) in order. Keep in mind these are all good oils, some are just a bit better than others at lubricating the clutch which makes for smoother shifting and less drive train stress.
1. Full Synthetic Silkolene Racing (this is a race oil)
2. Motul 5100 (smooths shifting!)
5. Mobil1 High Performance GOLD CAP
There will probably be people that disagree with me for all sorts of good reasons but that is oil. It always comes with a debate and a lot of opinions.
