I always find it interesting when manufacturers like BMW, Porsche, Mercedes or VW introduce a new oil specification because their requirements are so stringent.
I was poking around the Mercedes website and, if I understand it correctly, they now have a MB 229.81 specification. Source: "Engine Oil - Specified engine oils in cars & vans (service)" - https://operatingfluids.mercedes-benz.com/category/engine-oil/en . The documentation footnote says, "recommended for achieving lowest fuel consumption (lowest SAE viscosity class should be used; possible limitations of approved SAE viscosity classes to be noticed)".
I've searched the web and found no mention of the specification details or any oils that currently carry the 229.81 specification. The only thing I can find is that the motors that use this specification are installed in the Mercedes-Benz CLA vehicles. When I look at the owners manuals for these cars, they mention using 229.51, 229.52, 229.61, 229.71, and 229.72 (recommended for achieving lowest fuel consumption (lowest SAE viscosity class should be used; possible limitations of approved SAE viscosity classes to be noticed) but no mention of 229.81.
I wonder why there doesn't seem to be any details? Is there any way(s) to learn more about it?
Thank you,
Ed
