God how this oil thing goes on and on, on every motorcycle and auto site. No one has ever posted an oil related failure with a modern oil on any of these sites.
If the factory recommends it...it's my oil. No one has given me any ACTUAL reason to change and I challenge anyone to do so.
Most of this oil choice is based upon advertising hype from the companies that make or distribute the stuff but never a fact that has changed my mind.
