Gas Engine Oil

Gas  Engine  Lubricants

Gas Engine Oil is a heavy duty lubricating oil, developed mainly for highly rated modern engines using biogas or landfill gas as a fuel. This engine oil, formulated with high- quality, high Viscosity Index base oils and a special additives package, provides optimum control of deposits in severe conditions and protection against wear, rust and corrosion at high or low temperatures.

Gas Engine Oil is specially designed for gas engines used primarily for electricity generation, operting under heavy loads and harsh conditions and It offers long drain intervals and increased service life.
Exceptional deposit, wear, oil oxidation and oil nitration control, meets catalyst manufacturers’ performance, has very good detergent and dispersant propertiesand good resistance against formation of foam and corrosion.

  • Long service life
  • Good detergency secures clean engine components
  • Good resistance against nitration
  • Protects against valve seat recession
  • Good acid neutralizing capacities
  • Minimizes ring scuffing
  • Improving engine performance
  • Protects against rust and corrosion
