Unless you have evidence of high fuel dilution or some other issue, the oil will be fine.

No it doesn't. I know many here like Rotella for the price but in a shearing sump, it will shear faster than good synthetic oils.
I'm not going to argue as I have no actual data to confirm my claim,all I have is me riding the bikes,and shifting became notchy,faster when using Amsoil mc 10w-40 and M1 mc 10w-40 then when I use rotella.
I'm an Amsoil fan here so I'm not a hater whatsoever,and let me also say I've got a great many quarts of Amsoil bike oil in all 3 flavours,I'm just relaying my personal experiences with all 3 products.
I am an M1 hater though.
As far as data goes I will defer to sunruh. He has forgotten more about bikes and bike oils than I will ever know,and I consider his experience and word gospel when it comes to bike oils. So if he writes it,you can count on it to be true.
