Wow. I thought I had posted a reply to this yesterday, but now I don't see it. We'll try again...
On the Rotella site, there is a link to Forums, and on the Forums page, there is a Forum for Motorcycle Oils. The SHELL TECH EXPERT seems to pipe in, whenever he feels the need to set something straight, so apparently the Forum board is moderated by SHELL (hince the reference earlier in this thread).
So - How hot do our engines run? How hot do diesel engines run? Apparently SHELL only makes one viscosity of their Rotella T Synthetic, and that is 5w40.
