Actually it is Mercedes Benz that sets the European standard which is mirrored in the ACEA specifications. Most oils are self certified or certified by third parties and the results sent to the Standards body for approval. "Conforms to" is IMO as good as "Certified as conforming to" if the product is from a reputable brand name. Avoid so called Green Barrel oils which are cheap and unbranded with only an API specification number printed on the barrel end. Huw
