I would be cautious. Now that BP owns Castrol, you are dealing with a MULTI-billion dollar corporation not known to be especially ethical, or responsive to customer concerns. When you get that big, your marketing is no longer based on product quality/customer satisfaction, but only on advertising claims you are NOT required to verify.

Don't take my word for it. Just call Castrol or BP tech service and try to get a straight answer!
