Polaris HD 10w-50, weak sauce?

[DNVDMAX]

Over at polarisatvforums someone did a uoa with this stuff and zinc/phos content is pretty low. Nonetheless the wear numbers for this uoa weren't bad at all.

I'll just stick to 0w-40 M1 for my 570 and 850 Sportys. I might start going 50/50 of 0w-40 and 15w-50 in the summer.

Thoughts?

Zddp is only a small part of a finished formulation,so the lack of it doesn't mean much.
Wear numbers. Unless the engine being analyzed has developed trends the wear numbers are basically meaningless.
Why is it so hard to understand that wear cannot be accurately measured via a uoa. A uoa is done to monitor the condition on the oil and to see if there is any contamination. To make a leap and say less wear metals means less wear is just that,a leap.

I would take a look at Amsoil AUV 5w50 and run it with confidence yearly.

I've used M1 15w-50 for about 3,000 miles in my rzr. Changing it today.
