Read again, it says it "meets A3 quality specs". If an oil is actually A3 rated, it would list it down in the little spot where all the other specs that it meets are listed (SM/GF-4 etc.). Short of having hard evidence that Walmart synthetic oil of all oils meets the coveted A3 rating, one must believe that it doesn't in fact meet the actual spec but in fact is marketed to meet A3 quality.
