Your question implies that there is really only one function of motor oil that matters - how well it cleans. Hopefully most here on BITOG know better. Among other things, European specifications put emphasis on low SAPS, but also put a very healthy dose of phosphorus and zinc for wear protection. Some Euro oils, such as Mobil 1 ESP, use so much that they do not meet SN, SP or SQ specs. But ESP is still a well respected motor oil. BMW puts a lot of emphasis on HT/HS, which is also an indicator of wear.
Valvoline Restore and Protect may meet some of the European specifications. That would be great if it not only has the cleaning qualities it is respected for, but also meets the Euro specifications. All I'm saying is that they need to show that, as a bare minimum it "Meets" these specifications, but preferably do the required testing and submit for approval, so they can show "Approved" on their bottles.
If they can't do that, perhaps they could follow the lead of what Mobil 1 does with ESP, where they show that it meets SQ engine test requirements. That means something to people. I don't know if something like that could be done for the European specs or not.
