Engine oil

[VNA]

For oil it says use motor oil of a certain spec. Now if i meet this spec, great, if I surpass this with a super
oil of the 21st century then also great.

OK, here we go again.

Yamaha quotes obsolete API specs as recommended oil.  These are specs that date back to the 1980's and 90's.
As far as I know all the genuine motorcycle oil on sale in the UK is manufactured to obsolete API automotive standards.

Feel free to fill your bike with the latest super high tech API SM, but you might not feel so great once you find your clutch is wrecked and you need to get your bores honed and new rings fitted.

I mean you could fill your tank with a higher spec fuel such as methanol, but you know, I don't think it will get you far.
