EURO vs US: Why ACEA & API Oil Standards Don’t Match

We’re diving deep into one of the most misunderstood topics in the automotive world: the differences between American API engine-oil specifications and European ACEA specifications. I’ll be joined by a technical expert from Ravenol, one of the world’s leading high-performance lubricant manufacturers, to break down: - What API classifications really mean (Gasoline vs diesel categories, SP/SQ, CK-4, testing requirements, and U.S. emissions considerations) - How ACEA Sequences differ (A/B high-SAPS oils, C-category low-SAPS oils, and long-drain performance) - Why European and American oils are formulated differently - Synthetic oil definitions: U.S. marketing vs German regulations - The critical role of OEM approvals and why “Approved” and “Suitable for Use” are not the same thing.
