The stationary gas engine, just like the 4-stroke gasoline or diesel engine, transforms the heat produced by the combustion of gas into mechanical work that allows the operation of a machine producing energy. The fuel gas used can range from natural gas to biogas to severe landfill gases. Gas combustion is cleaner than gasoline combustion, therefore it does not produce soot in the exhaust gases.  However,  the gas combustion temperature is very high, resulting in a risk of oxidation and nitration of the lubricant. The use of gases containing contaminants (sulfur, halogenated compounds such as chlorine, silica, etc.) can lead to the formation of corrosive products during combustion.

Oil for stationary gas engines has 4 main functions:

  • reduce the friction between the metal parts of the engine, particularly between the piston and the cylinder.
  • protect parts against corrosion due to the formation of acidic gases during combustion.
  • reduce the formation of deposits on hot parts (valves, piston heads).
  • cool the engine by removing part of the heat produced during combustion.

Our gas engine oils

We have carefully selected our base oils and additives to meet leading engine manufacturers’ requirements and keep your engine reliable even under cyclic peak loading conditions. Special emphasis is put on the low-deposit tendency of our formulations to ensure superior engine cleanliness. NATERIA gas engine oils provide enhanced wear and corrosion resistance to protect your engine for longer.

Our lubricants for stationary gas engines: NATERIA

Our NATERIA engine oil technologies are designed to deliver extended service life, even with the most aggressive gas fuels (H2S, moisture, contaminants). Combined with ANAC oil and coolant monitoring services, we help you get a comprehensive diagnosis of your equipment and determine the optimal drain interval.
