I have already told you that. Approvals are minimum requirements. Some oils are better than others. But to start, oil MUST be approved to have a baseline whether that oil meets those minimum requirements. Not just o blender claiming it meets or exceeds. We know very well which approved oils are better than others even when it comes to same blender. We know that Castrol Edge 0W30/40 is step up from 5W30/40 although they have same approvals. But, they HAVE approvals! Meaning, they are not that junk Triax.
