Momenta RX9 is a high performance engine oil that provides proven protection to diesel engines operating in severe conditions for both On and Off-highway applications. This product has been blended with highest performance base oils and fortified with an advanced additive system which assures superior control of oil thickening caused by soot buildup and high temperature oxidation. It helps achieve reduced oil consumption and wear protection.


  • Improved oxidation stability to minimize deposit formation
  • Higher TBN to extend protection from acids caused by combustion
  • Better protection against valve train wear
  • Improved low temperature performance
  • Potential fuel economy improvement compared to conventional CH-4 heavy duty engine oils


These heavy duty engine oils are recommended for all types of diesel and gasoline engines where the manufacturer specifies the API service CH-4/SJ. They are especially suited for use in low temperature environments where extreme pumpability properties are required. These Oils are also suitable for on-road and off-road applications, including equipment that are exposed to extreme low temperature operations. This oil is suitable for use in moderate to high sulfur content fuel.
