They don't perform cleanliness the same. Some house brands mention nothing about cleanliness on jug labels and at their websites.
..... and yes, oils like Pennzoil Platinum remove carbon deposits, up-to 50%, depending on the buildup already existing and the crust factor. The more buildup - the less that can be dissolved by cleaning oils and intake sprays.
Maybe someday we will get pictures of a house brand oil that's been used for 15-18 years and 200+K inside a Korean 2.4 TGDI engine...... Equinox TDGI engine.......etc.
I would love to see a lifetime TGDI engine of Supertech, Costco, Rural King..... heck even NAPA, which I believe is one of the best housebrand oils available today.
I like to read and digest what I read. I like to look at pics and digest what's visible in those pics AND can I believe the picture-taker is telling us the truth. That why currently I rely heavily on what the oil maker tells us on their jugs and in their website. But someday, I will get to see pics of aged vehicles using housebrands under TGDI circumstances, for it's entire engine lifetime.
If / when I see those pics and believe they can improve a TGDI engine, I will start buying the housebrand products.
There is absolutely nothing in their formula that promotes greater cleaning ability than any other API SN+ oil. Not a single thing. The detergents and dispersants are not that different. What you read on the jug is 100% grade A marketing mumbo jumbo. There's plenty of engines out there running house brands that are nice and clean inside. It's just that most of the people buying those cheap house brands aren't your 0.5% of the population that actually wants to dig deeper into why oils work and therefore, probably aren't on BITOG. The act of changing your oil is FAR more important to keeping an engine clean than whatever brand of the exact same API rating you choose to use.
I couldn't care less for flashy marketing on a bottle. It means absolutely nothing to me. It was most likely put together by some white collar who's never even changed his own oil, much less formulated oil. I care about what's in the bottle. A brand could say they reduce wear 2x as well as the industry standard and be referring to Sequence IVA with a maximum of 90 and they got 45. In reality, 45 sucks, but it makes for a good marketing point.
