The Royal Purple 75w90 is fine. I use Valvoline synthetic 75w90 in the front but because my rear is grinding itself to oblivion,  I switched to..I forget..80 or 90w140 conventional because I change it so often...and it slowed the destruction...and made it a little quieter.

Dealer sold me Suzuki gear shaft oil (made for Suzuki ATV diffs) and said to use that in the Cforce 600. I see in the manual it says 80w90 GL5. So any good 75w90 should work.

Manual says change every 50 hours, but I think its a good idea to change it at the end of break in at 20h/200 miles.
