There are varying opinions with regard to oil and change intervals. Do what feels best to you..
My general feeling is to follow the manufacturer's recommendation for oil change intervals. In this case 6K miles is what is recommended whether you use amsoil, mobil one, or dino oil.
With regard to synthetic change, the general concensus around this part of the country (Rocky Mountain Region) is that 18K is when you should be free to convert. I converted at 19K and have had all sorts of seal related problems in the engine and transmission. There are those "in the know" that suspect synthetic as potential contributing factor. Also the "bike sitting without use for a long time" as another contributing factor.
Regardless of all this conjecture, I am currently using Amsoil, have a bunch left, and am not sure what I will do afterward. I may just switch back to dino oil. Not sure yet.
I think all this bantering back and forth is counter productive. I still am not sure of what the benefit is to using synthetic, really....
I was getting castrol for 2.50 per quart, could use it for 6K if I wanted to and then change. The bike ran fine. Can't tell much of a difference with synthetic other then what I think it is doing based on what I have been told. Yep, I spent the money. Yep I felt good about it. That was up until over 2400.00 in maintenance issues with seals and suggestions from various "industry authorities" with decades of experience saying that synthetic could have been a contributing factor. What the heck do I know. I just want to ride the bike and not have to mortgage my home to do so.
Thank you extended warranty.. But, I have less confidence in the bike now that I have experienced these issues.
Put it all in perspective. Oil lubricates. If you want to change every 3K, don't waist your money on expensive stuff. You are wasting your money if you do.
Just that simple.
