Perfect example of how someone who does not carefully read your post will get mislead. 15w50 weight
oil is exempt from the API limitations on SM
oil. So they can indeed have the higher levels of zddp. Now if you pick up that same oil with a different weight, that zddp you want can be
significantly reduced. And on the off-chance that oil has the SN rating after October and you see the words "Resource Conserving" on the label, forget it.
