I borrowed this from a post Marv D had over on NastyZ28.com (hope you don't mind...
)
It is rather lengthy and the guy repeats himself a lot, but there is some good information here...

I use 20w50 Royal Purple HPS in my 418.

If you look further down the list you will find Royal Purple 10W30 HPS rated at #131...
And if you read and believe the data, viscosity plays no significant role in wear protection.

Wear resistance is a measure of the oil's ability to maintain its original viscosity after being severely worked.
They measure the viscosity before and after running the oil through a special diesel fuel injector.
The wear resistance is just a comparison of the before and after values.
No one viscosity oil is going to have an advantage over any other viscosity.
Unless I am totally missing something.

From what I have read, the standardized test for an oil's wear resistance is not dependent on its viscosity, at all.

That is what I said. Not sure whether your comments are agreeing or dis agreeing with me?
I was just referring to the article that said he found that viscosity had little to do with how well the oil protects engine parts against wear...and I agree.
The only reason I brought up the viscosity issue at all in my thread above was to point out to "Russ K" that there was probably no difference in the wear protection capabilities in the oil he uses (RP 20w50 HPS) and the one 540 rat tested, RP 10w30 HPS...
