ACEA (European Automobile Manufacturers Association) Ratings aren't really any different or more stringent than those from API (Am. Petroleum Institute) or SAE (Soc. of Automotive Engineers), it's just those crazy Euros coming up with their own system to prove that they - the United States of Europe, aka the EU, are just as good as we are.
And, don't confuse a ratings claim as a certification. NO oil is ACEA
approved - the ACEA does not approve motor oil. The Mfgrs. are just claiming to be in compliance with ACEA testing standards. Oil mfgrs. are responsible for their own testing and conformance to ACEA specs is voluntary. Just because a manufacturer doesn't claim ACEA compliance for their product, doesn't mean it isn't, especially if they are already complying with API or SAE specs.
I think we're seeing waaay too much Oil paranoia here lately. People obsess about which oil to use and then add a K&N or Gauze filter which introduce far more contaminates than oem, or go 15k mi. between service intervals. That's kinda like smoking in the doctor's waiting room.
Choose a name brand synthetic of your choice, swap between 7500 or annually (unless your conditions dictate otherwise), and you'll be fine. Using MB1 under these circumstances will not increase the odds that you'll grenade your engine anymore than if you choose Pirelli or Continental shoes for the car. Remember,
EVERY Boxster leaving Stuttgart or Uusikaupunki, for better or for worse, has a belly full of Mobil 1.
If your engine does implode, it's much more likely that the poorly engineered IMS bearing or RMS are to blame.
