I don't know how to interpret the viscosity numbers. Is your 59.9 based on 10W40, or some other reference number? If it's based on the original oil viscosity, and mine is 60.9, does that mean mine has sheared to around 10W40? Whatever it is, both analysers suggested we could do longer runs before changing our oil. It doesn't seem that there's much difference between using 10W40 or 10W50.

I think it's saying both oils sheared down to a 30 weight oil.  My 10W40 after 3612 miles and your 10W50 after 7000 miles.  Can't say if it took that many miles or it sheared earlier and sort of stayed there, however.  I readily admit I'm NO expert on the subject (or any subject for that matter).  Here is the chart I recall seeing:

Here is a link to the original https://www.bobistheoilguy.com/viscosity-charts/ that hopefully explains more.

I enjoy reading all the posts from self-proclaimed, and some real experts there.

As promised, I had a Laboratory Analysis performed on my oil at my 20,000 mile Service. I accumulated 10,006 miles prior to this Service.

Given the extended interval recommended by Triumph, I decided to research synthetic motorcycle oil prior to my 500 mile original oil change, and decided to go with Motul 7100 Series 10W40 Ester based synthetic motorcycle oil, primarily due to claims of superior stability against shearing, and a better detergent additive package.
The Triumph recommended Castrol Power 1 Synthetic currently sells for $48.50 for a six pack of quarts, the Motul sells for the same price for a 4 liter container.

I must admit that the results exceeded my expectations. The Viscosity did not break down appreciably over 10,000 miles, and the additive package was not depleted. Based on the Lab Reports posted in this thread, I believe the Motul is worth the extra cost, and plan to use it from now on for the recommended 10,000 miles between changes.

You make a good argument for the Motul. It's neat to be able to see a side-by-side report.

I also always put Motul 7100 Series 10W40. I noticed that it has more vitality than Castrol 10w40, more durability and better engine sound.

With Castrol 10w40, oil changes always came out black making changes every 10,000 km, which is when I always do them.

Every change I make with Motul 7100 Series 10W40 the oil still comes out with something red, which for me is a good oil.

And now you know that you can extend your oil change interval if you like, as well.  :028:

Where did you send the oil analysis to and what was the cost?  I run rotella in all my bikes and would like to compare to the other oils.
