When I bought this, it did not specify which variant of the 5w-40 this was. Ordered to find out. It is the MST version, the mid-SAPS oil.
This is neither a good nor bad thing. What it means though is that in gasoline vehicles in the US, due to the sulfur content in the fuel, you will get faster TBN depletion than with a full-SAPS version (the HST version of this oil has a TBN of 10 versus this which is 7.1). With a TBN of 7.1, it is not definite whether it is a 10k mile OCI oil, but it will do better than 5k miles, which is just about doable with a low-SAPS oil.
It is a pretty light 40wt, good for economy.
After a 5k OCI and a UOA, Ill update.

Best Deals for Valvoline SynPower Full Synthetic Motor Oil SAE 5W-40 - 1 Quart
Great stuff, one of the best synthetic oils out there. Use it gas and diesels vehicles and it's certified by many manufactures for both uses. Sad to they just jacked the price up so I'm back to my local NAPA store for a lower price. To bad for Amazon as it was the place to buy this great motor oil.
Different grades different certifications; 5-40W is the only one with certification for TDI and other diesel engines as well as all gas engines. Great stuff if you run a multi-fuel fleet.
From Valvoline web site......
SAE 5W-40: Provides the widest range of protection available in the SynPower motor oil line. Delivers outstanding cold temperature pumpability for rapid oil circulation at start-up. Provides a thick oil film for ultimate wear protection. Exceeds all car and light truck manufacturers' warranty requirements for the protection of gasoline, diesel and turbocharged engines where an API SL, SM or CF oil is recommended. SynPower 5W-40 exceeds European ACEA A3/B3/B4/C3 requirements and is approved for Mercedes-Benz, and Volkswagen. SynPower 5W-40 also meets the engine performance requirements for BMW, Jaguar, Porsche, Lexus, Rolls Royce, Volvo and other high performance vehicles.
No other oil in Valvoline's lineup has this broad of a range use or certifications for Gas or Diesel. Just a side note I have not been able to find an oil from any other manufacture that can match it. As an example of why I use this oil I have a TDI with over 350,000 miles and the only thing ever touched on the engine is the timing belt every 100,000 and a couple of glow plugs. I also have several others vehicles well over the 100,000 mile mark with no engine failures.
Honest reviews on Valvoline SynPower Full Synthetic Motor Oil SAE 5W-40 - 1 Quart
I've used Valvoline SynPower SAE 5W40 in my 2006 Jetta TDI from 50,000 to 70,000 miles. I think it's a great oil that holds up as good, if not better than, Castrol SLX or Pentosin. I'm not tearing the wheels off my car, but I have a two hour commute to work and I average about 75 to 80 MPH on the highway. The price is good also!

This is definitely the best oil out there, I've heard about royal purple being good as well, never tried it, but, this one is just great. The engine runs unbelievably quiet and smooth.
