1st video is complete marketing, 2nd video completely independent, 3rd was a tour and explanation of why it's great but all from Valvoline. Independent video showed a 2008 F150, unknown miles or history, tons of sludge in the engine that came out with the oil. 1994 Camry didn't have much come out of it. Interesting that with the F150 he recommended a case of oil filters and replace them every 300 miles but the 3rd video Valvoline says (15:00 in) their oil won't remove sludge fast enough to clog the filter.
There are tons of oil cleaning additives on the market (Liqui Moly, Seafoam, other), with the Camry being 30 years old, well maintained and showing it's clean, I won't buy this oil as I don't have a car close to this old and also maintain mine in a similar way.
All the different additives and extra cleaners seem suspect to me as they are assuming what comes standard isn't good enough. Like using 2x the soap to wash your hands, if they come out clean you don't need more soap.
