Had mine 10K servicing with Terrence last Sunday and I'm now officially a 20wt oil convert!
The engine now no longer has to cope with the crappy 20W50 mineral used by C&C.
Decided to go with a 20wt as it was highly recommended in the user manual, experience with M1 0W20 for the past few days was a pleasant one, I'm surprised by the throttle response and smoothness. Besides that, engine note was much softer during cold morning starts.
Honestly, it took me quite a while to overcome the 20wt barrier and I'm glad I did.
I have also added a few ounces of LC20 to beef up the oil.
Will be draining the oil out at 7.5K for an UOA to determine engine health, was told 5W20 EP is reaching our shores soon.
