Bob, MaxLife is not intended to be an Auto-Rx replacement. You know that, and hopefully most everyone on this forum knows that. MaxLife may serve a purpose. It may provide a prophylactic benefit over the course of continual use. At $0.20/qt over their All-Climate conventional oil, it may not be a bad deal. Who knows? Oil analysis will only tell you so much and I'm sure that you and the good folks at Schaeffer's do not know about Valvoline's research and empirical data. People have a tendency to work within their framework and not venture out. MaxLife may be more than the sum of it's parts.

Bob, most synths containing esters have ingredients to counter the swelling, like PAO in Mobil 1. And who knows... 9% esters may be the magic number to provide a benefit without leaks. You don't know. I don't know. Only time will tell.

Bob, detergents are relatively inexpensive. If it was that easy, I'm sure that they would have added them. Again, you and I don't know their goals, the science, the empirical data, and the long-term results.

Bob, none of your experiments characterize, emulate or even approximate the engine environment.

I agree if it is desirable to do so, quickly. That was not Valvoline's mission.

You are entitled to your opinion.
Maybe MaxLife conditions seals as well as any other ester-based synthetic on the long run. But for $0.20 over the price of conventional oil, it's not a mere marketing ploy. It's called value.
