Thanks. I am using Motul 5100 15W50 (Semi-Synth). (Yamaha recommends 20W40)

Thanks. I used to follow the same - this is the first time I have exceeded 2000 kms ( but not 6 months - change the oil once before the onset of monsoon : by June and once in winter by end November; new oil + cold Pune air = sweet sounding engine
So guess that larger kms (or longer drain interval) does affect the performance.
