My shifts are fine. The Rotella actually comes in a 3.75L jug. Use it all. The level is dead on in the sight glass.

I really believe the Rotella-T 15W-40 would be more than adequate in our engines as well, though not synthetic. What does "synthetic" mean anymore anyway, right?

These oils are so "over-engineered" for the commercial duty applications that using them in our engines, and changing the oil as often as we will - its a walk in the park. I'm not concerned about the viscocity - extreme heat is what this stuff is primarily engineered to withstand. Where I live, I'm certainly not concerned with the cold starts. It is not a matter of $$$$ - I just don't like being backed into a corner (by Triumph), and told that I can only use one thing, and I can only get it one place, at their price.

I really hope more of you read that whole ST1300 write up. I'm not touting (or knocking) Honda, and I don't own stock in Shell. The article was very informative, and I appreciate anyone who would take the time to put that much effort into something and then share it with the rest of us for free. I learned a lot about oil, and oil development reading this, and I've been in the auto service industry half my life. I have shared this info with others I work with, and all agree it is quite informative/interesting.

This topic keeps popping up on this site, and I'm sure it will again before the week is over. That's okay. At least we are not all a bunch of lemmings running down to the Triumph store to pay their price for their oil. We have choices. (This is AMERICA)
