I think you pretty much know how oil threads go but what the hey. Synthetics are "supposed" to last longer than dino oil and have a longer life due to superior properties. I personally have a problem with this. I get flamed for the next statement as a rule. "Dirty oil is dirty oil", there I said it! Contaminates are the same in a crankcase full of dino as they are in synthetic. But the properties of synthetic are supposed to support these contaminates longer and better than dino therefore they are doing the job longer. But IMHO, they are still there doing what they do in any oil, add wear no matter how small.
I have run the dog crap out of Rotella 15X40 (JASO-MA rated) and have as much faith in that as any synthetic. When I purchased my Touring they told me 10,000 as well, but I won't even go by that. At 500 miles they told me Castrol is all I am to run... Hell, there was even a Castrol sticker on the bike by the oil fill when I bought it. They also told me Mobil 1 20X50 isn't what they advocate to use? I ran that in my Harleys and never had a problem.
So as I see it, do what you want, just use good wet clutch approved oil, but I personally will still change oil / filter at the mileage "I" want, 3000 miles. Expensive, ya, necessary, maybe not, but I paid good money for this bike and oil matters, "to me". To each his own....10,000 is a very long way too run in my estimation, and you know what they say about opinions. This is just mine.
