The European Automobile Manufacturers’ Association (ACEA) helps establish motor oil standards in the European market. ACEA recognizes that European engines differ from U.S. engines in both design and operating conditions. As a result, the demands on motor oil are different as well. The differentiator between various makes and models of European cars has to do with the acceptable levels of sulfated ash, phosphorus and sulfur (SAPS) in the motor oil. Sulfated ash is the by-product of metallic compounds as they are burned. It can improve an oil’s antioxidancy, anti-wear properties, Total Base Number (TBN), corrosion resistance, engine cleanliness properties and soot-handling ability.
Phosphorus is present in motor oil for its antioxidant properties. Sulfur provides antioxidancy, anti-wear and engine cleanliness properties.
SAPS makes up a significant portion of a motor oil’s additive content. Some emissions systems and aftertreatment devices, such as diesel particulate filters (DPFs) and catalysts, are sensitive to the SAPS content of oil and require lower-SAPS formulations to properly function for a long period of time.
