GEN-GUARD Gas Engine Lubricants

GEN-GUARD is Rock Oil’s specialist range of lubricants for stationary gas engines and associated power-generation applications.

Gas engines place particular demands on lubricants because of their high operating temperatures, extended running periods and exposure to different fuel qualities.

Depending on the application, gas engine oils must help control deposits, protect valves and pistons, resist oxidation and maintain the correct ash level for the engine and fuel type.

GEN-GUARD products are developed to support:

Engine Cleanliness

Advanced detergent and dispersant technology helps control deposits, varnish and contamination, supporting clean and efficient engine operation.

Wear Protection

Lubricant films help protect bearings, cylinder components, valve trains and other critical engine parts operating under sustained load.

Oxidation Resistance

Gas engines can expose lubricants to prolonged high temperatures. Strong oxidation stability helps resist oil thickening, deposit formation and premature lubricant degradation.

Controlled Ash Performance

Correct ash content is important in stationary gas engines. Too little may reduce protection in some applications, while too much can contribute to deposits and pre-ignition.

The lubricant must therefore be selected according to the engine design, fuel composition and equipment manufacturer’s requirements.

Extended Lubricant Life

Selected formulations may support longer service intervals where permitted by the engine manufacturer and confirmed through suitable oil-condition monitoring.

Specific GEN-GUARD products, performance levels and manufacturer approvals should be added once the current technical range information is available.

Lubricants for Different Gas Types

Power-generation engines may operate on natural gas, biogas, landfill gas, sewage gas or other gaseous fuels.

Fuel composition can significantly affect lubricant performance. Sour or contaminated gases may introduce acids, siloxanes, sulphur compounds or other contaminants that place additional pressure on the oil.

Correct product selection should consider:

• Gas quality and composition.
• Engine type and manufacturer.
• Required ash level.
• Operating temperature.
• Oil consumption.
