Gas Engine Oil MA 40 Rvn no : 1

Gas engine lubricant

Gas Engine Oil MA 40 is an heavy duty lubricating oil, developed mostly 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, providing optimal control of deposits in severe conditions and protection against wear, rust and corrosion at high or low temperatures. It is specially designed for gas engines used primarily for electricity generation, operating under heavy loads and harsh conditions.
Gas Engine Oil MA 40 is compatible with exhaust catalysts of NSCR-type, has excellent resistance against formation of deposits,
maximum protection against corrosion andnitration, protects valves and minimizes corrosive wear.

  • Long service life due to a high oxidation resistance
  • Good detergency secures clean engine components
  • Good resistance against nitration
  • Protects against valve seat recession
  • Good acid neutralizing capacities
  • Protects against rust and corrosion

The OEM recommendation regarding the selection of the ash level should always be followed.
