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

[demarpaint]

I'd try it.

I'd probably try it too, if I bought a used car with an issue. Or I was trying to free up a lifter, maybe for an oil consumption issue. It might just be the ticket to hold off tearing down an engine to replace parts that might have a bit of junk messing things up.

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

Please don't overlook homogenized and pasteurized.

Problem is that most don't want to change their oil... they want to run it for a few years, never check the level, and reuse the filter multiple times

Most of the products with colloidals aren't homogenized. Shake that bottle extremely well. Might have to refill it with a few ounces of motor oil and shake again to get all the stuff on the bottom of the bottle.

Since its not edible, not worried about pasteurization.
