I do recommend getting the OS Giken fluid with it because I've spoke with someone else who has it and used the Motul fluid and got a whine when cruising down the highway for a little while but I haven't had that issue. I would like to drive a Carbonetics and Quaife just to feel the difference if any though. Would be nice to have a comparison for a write up !
