Exactly. I would have no concerns in using their products (and I use some of their stuff), but "meeting" and "certification" are different things. Regardless of what they claim, GF-5 is not compatible with A3/B3/B4 and the other European specifications. There are no 5w30 GF-5 oils with an HTHS of 3.5 or above, and there are no A3/B3/B4 oils that meet GF-5. A1/B1 sure, but not A3/B3.
