Yes, agree. I did my own research and found the MB spec sheet with list of motor oils acceptable for all MB engines. The QX30’s M270 2.0 Turbo engine is OK with 229.51oil in Europe but it is not OK in the US.
Interesting, on Valvoline’s oil spec sheets a footnote says its 229.51oil can be used in place of 229.5. In any case, I’m taking it back for a change!
