This is Valvoline's latest entry into the after-market add world.
The base fluid is an Amber-Dyed olefin copolymer, polyisobutylene, and a surfactant with a hefty dose of AW/EP and FM adds - note the moly content. The moly content should boost the moly in an oil by 100 ppm for a 4.5 Qt. sump. The calculated boron level is 40 ppm. No defoament is present in the form of silicons or siloxanes.
The TBN is nice but the TAN starts out a bit high. I would prefer to see it at 0.5 or lower.
IMO, the price per oz. of $0.33, is a bit high for an OTC aftermarket add.
The base fluid thickness will fool you. It sure appears heavier than an SAE middle 40 weight. If you're going to add this to your oil, make up a batch and send to TDyson for viscosity analysis at 100 C. Adding this product to your oil may bring it up and out-of-grade.
