Whatever the oil manufacturers claim, their recommendations will never override the engine manufacturer's recommendations.
For having been in the oil business for several decades, I would much more prefer for my Benz to bath in a cheap no-name .99c/q recycled oil (as long as it meets the SAE specs) than in a 12,000 or 15,000mi. old expensive synthetic oil.
Mobil 1 or a cheap recycled oil will collect the same amount of contaminants for the same mileage.
