Quote: I presume the VR means it's a 'Valvoline Racing' oil? No it doesn't have VR-1 on the bottle. It also doesn't have SM or SN on the bottles. It's been a couple years since I bought this case. I'll be needing some more sorta soon.
Info here on the 3 different VR-1/Racing Oils available;
On their specs sheet they state that VR1 has between 1300-1400 ppm. 1300 ppm is within the uncertainty of our measurements, so Valvoline seems to be telling the truth. They're on of the few manufacturers that will give ZDDP concentrations. For what its worth, Rotella T seems to be the best bag-for-buck. Of course there is more to oil than just ZDDP concentrations...
