I wouldn't buy a Yamaha just because of this but would sure take advantage of signing up if I did. I've been partial to OEM oils for many years, filters too. Yamalube has a good reputation, Honda, BMW, etcetera. BMW has a new oil, Advantec, made from natural gas. Eliminates virtually all impurities from the base stocks but a little more expensive.
