Low-Emission Oils: The Ultimate Guide to Low-SAPS Lubricants
Traditional engine lubricants use performance-boosting additives, such as phosphorus and sulfur for their anti-wear and antioxidant features. However, phosphorus and sulfur may damage the depolluting after-treatment system. Thus, oil manufacturers designed a series of oils that have low levels of sulfur and phosphorus. In the automotive lubricants industry, we call them low-emission or low-SAPS oils.
