Berryman High Mileage Oil System Rejuvenator. What the heck is this stuff?

Petroleum Oil 64742-6- 50-60%
Zinc Dialkyl Dithiophosphateproprietary 2-5%
Polybutylene Succinimideconfidential 2-5%
Organomolybdenum Complexproprietary1-2%

so 55-72% that stuff and 28%-45% unlisted
 
With moly and zinc this could be something to consider.
But would need to know more precisely how much so as not to overdo it.
 
This product and their oil extender need VOA's. Would be interesting to see how much more more more more is there, along with visc...

Their HEST combustion chamber cleaning kit was excellent. It was replaced with the intake valve combustion chamber cleaning kit, which also is excellent and more idiot proof. B12 does 'market' some excellent products.

Today's oils are so good that we never ever see excessive oil consumption, crud/carbon'd ring grove/lands, varnished/sludged vvt screens, start up noises, worn timing chains, and engine issues repeatedly. Everything is blended to sell at a price point.

If you have an oil burner, your 1st bottle of top off should be snake oil.
 
So Berryman claims oil should be "Rejuvinated"

Lucas claims oil needs to be "Stabilized"

I say if oil needs to be "Rejuvinated or "Stabilized 'or "Fortified" the best way to do that, is to change the OIL
