Product Features

TotalEnergies Nateria MJ40, a specialized lubricant meticulously engineered to meet the unique demands of industrial engines operating in challenging environments. Specifically formulated for engines requiring a medium ash oil to neutralize high levels of hydrogen sulphur (H2S) and impurities such as halogens and siloxanes found in gaseous fuels, Nateria MJ40 ensures optimal engine performance and longevity. Ideal for engines running on untreated biogas, sewage, and landfill gases, this lubricant provides reliable lubrication and protection, even in the harshest conditions. Additionally, Nateria MJ40 is suitable for engines where higher ash levels are preferred for optimized piston head life and valve recession control, offering enhanced durability and efficiency. Trust TotalEnergies Nateria MJ40 to keep your industrial engines running smoothly and efficiently, maximizing uptime and productivity in critical operations.

Extended Drain Intervals
  • NATERIA MJ 40 contains hydrocracked base oils selected for their high thermal stability, nitration and oxidation resistance.
Increased Engine Protection 
  • NATERIA MJ 40’s specific additive system demonstrated excellent TBN retention and antiwear performance in the field.
  • NATERIA MJ 40’s elevated TBN is ideal in neutralizing acids coming from the gas combustion or impurites to give longer drain intervals and keep engine parts cleaner.
