  1. EXC Oil

    Off-Road / Enduro
    I've just picked up a new 2010 450 EXC and the reccomended oil is Motorex 10W/50 Full Synthetic oil. I still have 8 litres of 10W/40 Shell Advance VSX4 that I've used in my '03 450 EXC for the last 3,000 odd miles and wondered if I'd be ok to carry on using this. It's supposed to be pretty good...
