Valvoline has one of the best engine labs among all the oil brands. They are capable of running all 5 API engine tests in-house. Valvoline remains a brand that suggests you follow your owners manual for oil drain intervals. I can't say I blame them, but I'd like to see them put out a premium, top tier oil that is on the level of Mobil 1/Amsoil/Edge EP. Their "Modern Synthetic" was poorly marketed and just doesn't add up. The price is high for a product that has no explanation of why it's better than competing brands for intake valve deposits. I would even argue Mobil 1 was way ahead of them on that as their Noack is better and the SA levels are .8. Valvoline is a quality oil though and I'd use it in a heartbeat. The Noack volatility of the regular Valvoline FS 5w20, 5w30 and 10w30 are quite impressive at 7.6%, 9.3% and 8.0%. Not bad....
I've had a good experience at their VIOC as well during the few times I had to go there for my gf's car.
