Wondering how VRP could have helped vehicles you have owned in the past.

My 1963 Chevy Bel Air 283 would have needed an IV of VRP. The valve covers were so caked with sludge you could just see the indentations the rockers made.

I had a Lexus LS 460 years ago and at around 115,000 it started using some oil, then by 150,000 a little worse…by 170,000 it was burning a quart every 600 miles or so. A lot of oil tracking back up into the intake. Rings were either shot or stuck. I do wonder if this miracle magic oil would have maybe saved it. Doubt it, but who knows?

I had a 1992 V6 Dodge Grand Caravan that religiously received Valvoline White Bottle Conventional oil every 3,000 miles / 3 months. That engine plus the Valvoline white bottle oil produced sludge like it invented the term !! … Then there was the bad Dodge Caravan transmissions (uhh !) Not sure if VRP would have helped that Dodge heap or not ?
