Depends on what Rotella oil is used.
I have run T6 (blue bottle) and most of my bikes shifted rough after about 1000 miles.
For the last 10 years, I have used the Rotella T4 (white bottle, JASO approved) 15w40 and have had stellar results with it. The new-to-me FJR is at about 2500 miles with the Rotella T4 in it and no problems.
My 135,000 mile Kawasaki ZRX1200 has run nothing but Rotella T4 15w40 and up to 7000 mile changes while on two-week trips. Blackstone Labs has tested the oil out of that bike 4 times now and every test comes back with excellent results. I even have them run the TBS to see how much life is left in the oil and they have said I could safely extend the service life out to 9000 miles on the change. Not that I am going to do that, but there were still enough additives and viscosity life in that oil to go further.
That all being said, I don't buy Rotella to save a few bucks, as the wife and I live comfortably. I do have plenty of Rotella 15w40 here to change on my tractor, mower, truck, three bikes and whatever else comes along. The wife's new Mazda gets 10w30 T5 Rotella. The oil works for my needs, is readily available and doesn't hurt a thing. Remember, I use the JASO approved Rotella.
This is just a report of what I do. In no way am I suggesting whatever oil anyone else may use is wrong. So before anyone gets their knickers in a bunch and whatnot, this is a IMHO and YMMV post.
ReRose will come by and say he uses Rotella as a flush oil, but in reality, what he neglects to say is he has to use flush oil because he can't keep carburetors from leaking fuel into the crankcases of his bikes. He's just cursed like that.
