I'm not sure if this is Valvoline or not, because it was a car purchased from a dealer. Who knows what he put in there? BLACKSTONE LABS WRITES: "Wear levels are right where they should be, and that's a good sign the internal parts are healthy and wearing well. The TAN read 2.2 and the TBN at 5.1 shows plenty of active additive left in the oil. The trace of fuel is harmless, and the high sodium is just detergent/dispersant additive, not coolant. This sample looks good from here -- nice engine!"
