I got vr1 10w-30 for my next two oil changes. See how it works out.

How much does something like this run, David?

Quoting GEDengineering:
Valvoline VR-1 20w-50 it is cheap and has high additives that help protect all the bearing surfaces in the engine and turbocharger. FP wrote a very good test article about the different types of oils and how ones without additives (most synthetic oils) will destroy journal/thrust bearings in turbochargers. The higher the phosphorus and zinc content in the oil the better, those soft metals are like little cushions and carry load very well.

You'd be looking at $28 for the standard test. On this one, i opted to have them check the TBN (+$10) to see how much of the additive package was left. It's only really important if you are trying to extend your intervals...you would basically keep extending the interval until the additive package gets close to 0. That wasn't my goal here, i was just curious to see what it looked like. Next one i won't opt for TBN.
For anyone who is interested, you can have them send you some free test kits here.

Closing the loop here. M1 15w50 gets a pass...for at least one track day and some street driving anyway.
Last UOA had the M1 15w50 looking more like a 0w20 after 3k miles, one track day, and a strenuous dyno tuning session.
I was about ready to write off this oil and begin looking at better alternatives, albeit with a price tag 2.5x times higher. Before doing so, i wanted to do another UOA, this time the only use being driving to the track, at the track, and back home.
I was pleased to see that it held up just fine. Good thing, because i've still got another 10 qts of this stuff on the shelf, and i'm happy to continue paying $5/qt for decent performance and detergent/zinc/phos levels.
