Well hell if thats the case, why the 0W20 lol. Seems these engines can really safely run any oil we want

I guess one could also say their statement that Dexos 1 oil meets the specs for this engine is bullshit. Since now they say it’s R,any oil that lubricates should work just as well lol. Kinda debunks their own myth yeah.
