Application Bulletin: ZDDP alternative for Premium Engine Oil
Ultrium™ 6700 - Zero-SAPS, Ashless Anti-Wear Technology as a replacement in lubricant formulations
The drive to minimize sulfated ash, phosphorus and sulfur (SAPS) content in engine oil has intensified primarily to address debits of exhaust aftertreatment catalyst poisoning, improve fuel efficiency, minimize particulate, decrease SOx / NOx emissions. These advances help to futureproof engine oil amid increased governmental regulations.
Traditional anti-wear additives such as ZDDP, while highly effective in boundary lubrication regimes, present challenges due to their thermal instability, volatility, and contributions to SAPS levels. This necessitates the development of innovative additive chemistries that maintain engine wear protection and oxidation resistance without relying on traditional aggressive sulfur and phosphorus-based chemistry.
Ultrium Technology in ActionAurorium Ultrium® 6700 is a multifunctional polyester-based additive platform developed to address the evolving tribological and durability demands of modern passenger car engine oils. Its chemically engineered ashless architecture—free of sulfur and phosphorus—offers a unique pathway to enhance base oil solvency, deposit control, and oxidative stability, while maintaining compatibility with conventional anti-wear systems such as ZDDP. This enables formulators to optimize additive balance for next-generation low-viscosity formulations, improve fuel economy performance, and meet increasingly stringent OEM and environmental specifications without compromising wear protection or cleanliness. |

Why Choose Ultrium 6700 for your Engine Oil Formulations?
Ultrium 6700 functions by developing a robust boundary film on the internal wetted surfaces, such as piston ring areas thereby providing asperity level protection. In addition to improving lubricity, Ultrium 6700 also contributes to corrosion mitigation and deposit control, further enhancing the reliability of the engine oil under demanding operating conditions. These make Ultrium 6700 a premier choice for formulators seeking to improve hardware protection and system efficiency in advanced engine oil platforms, delivering diverse formulation strategy. |
