Momenta RX9 combines a high quality synthetic base stock with a proprietary, balanced additive system having a combination of metallic detergents, dispersants and multi-purpose inhibitors. This oil assures superior control of oil thickening caused by soot buildup and high temperature oxidation. It also provides outstanding resistance to varnish deposits and corrosion.


  • 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 sulphur content fuel.
