In my experience Schaeffer's, like Redline products, do not carry the starburst symbol and are not formally certified by the API or any one else for that matter. Not that they aren't good oils as they most likely exceed any standard, but for the sake of the thread and meeting warranty guidelines, going with an API certified product seems to be the important point here.
So as others suggested, any traditional name brand within the grade requirements and that is API SN with the associated approval labeling should be the right choice.
Your experience is tainted.
Schaeffers has approvals on MANY MANY MANY of their oils, if not most, depending on the decade of approval and for that particular machine.

All I see is "compliant" and "meets and exceeds." I don't see anything with "approved."
There is also no Dexos 1 logo on the front of the bottle which is usually the norm for formally approved Dexos 1 products.
