hey mate, yeah 10w40 for the engine, and either motul 8100, 300V or turbolight 4100, royal purple, sougi s6000 or m5000 (if you can find some) all seem to get good ratings. some people prefer the mobil 1 0w40 etc, but each to their own.
on the gearbox oil, im changing mine today with castrox vmx-m 75w85 with a small bottle of the nulon g70 additive. wanted to go pentire sin75 but out of my pricerange for a little while...
im sure birds will respond, how will the vmx-m go?
