Single grade such as SAE 30.....usually does not have any API gasoline engine code after the diesel codes.
This one just says cj-4. I was hoping someone would have a link to a site that would say it is SM. I guess if it doesnt say it on the bottle it really isnt. It sucks because its a good price. The rotella 10w-30 and T6 are SN rated aswell as the delo 5w-40. I was hoping this would be too.
