Valvoline Restore and Protect Anyone try it yet

I have not seen it on the shelves yet and want to try it in my moderate mileage N52. Hoping to get rid of some sludge and so forth.

YT channel The Motor Oil Geek recently had a video about top tier gasoline being better for oil life (because of how it differently affects rings); and has several on oil analyses and comparisons. The core advice from many seems to be oil and filter changes every 5k miles or shorter. Doesn’t matter what vehicle, manufacturer or engine.

This sounds like a question better asked in the "topic" sections of this forum.....

I put here because I know at some point it will go off the rails.

Is sludge at all likely in modern BMW engines?

That is, without extreme neglect, PCV system issues, or something like coolant getting into the oil without it becoming evident.

I've not thought about sludge as a possibility in many decades.

Because it's a nonissue.
If I can watch hands full of videos about vehicles going 40,000 or more miles with no oil change or top off at all then it should be clearly obvious that if you stick to a reasonable oil change interval that you will have no sludge issues.
Hell the vast majority of people thinking the latest and greatest will save their POS will never keep it long enough to prove anything. Come talk to me when you've put 200,000, 300,000, 500,000 miles on the car.
