Tom has the tremendous knowledge base and work experience to completely back up what he has stated.
I have seen where Super S 5w30 full synthetic claimed a oil met Dexos and MB 229.5 and Porsche C30. Which made no sense because Dexos oils are almost always 3.0-3.2 HTHS. MB 229.5 and C30 is a thicker oil to meet that approval that has a HTHS of 3.5 or a bit higher.
"Suitable" was the wording in this case. I would not run that Super S 5w30 in a Porsche C30 car or a MB.
