AMSOIL 100% Synthetic Stationary Natural Gas Engine Oil

Synthetic Stationary Natural Gas Engine Oil SAE 15W-40

Formulated to Provide Top Efficiency in Stationary Engines Fueled by Natural Gas

AMSOIL Synthetic Stationary Natural Gas Engine Oil delivers superior protection in stationary natural gas engines calling for an SAE 40, low-ash lubricant. Its shear-stable formula qualifies it as a multi-grade 20W-40 so it can be used over a broad ambient temperature range, reducing the need for seasonal oil changes.

Controls Wear

AMSOIL Synthetic Stationary Natural Gas Engine Oil is formulated with low sulfated ash to minimize carbon deposits and port blockage, resulting in reduced maintenance and extended equipment life. Advanced anti-wear and anti-scuff protection helps control valve recession and wear on piston rings, cylinder liners and bearings during continual severe-service operation.

Keeps Engines Clean

AMSOIL Synthetic Stationary Natural Gas Engine Oil is engineered with premium base oils and additives to improve engine lubrication by keeping oil passages clean. Its balanced formula allows for a high total base number(TBN) to protect against corrosion while meeting low ash requirements.

Controls Nitration

Nitration is a common concern in natural gas engines and can cause oil to thicken, reducing efficiency. AMSOIL Synthetic Stationary Natural Gas Engine Oil is naturally resistant to nitration, delivering maximum engine protection.

Protects Emission Systems

AMSOIL Synthetic Stationary Natural Gas Engine Oil is formulated with low zinc and phosphorus levels to prolong the life of emission catalyst systems without sacrificing wear protection.

Delivers Long-Lasting Protection

Extensive monitoring by oil analysis has proven that drain intervals can be safely extended with AMSOIL Stationary Natural Gas Engine Oil. When extending oil drain intervals, change the oil filter at the equipment manufacturer’s recommended interval.

• Guards against valve-train wear
• Fights valve recession
• Helps reduce oil consumption and emissions
• Capable of extended drain intervals with oil analysis

APPLICATIONS

AMSOIL Synthetic Stationary Natural Gas Engine Oil is recommended for use in stationary four-stroke and two-stroke engines that require low-ash (<.50%) engine oil and are fueled by natural gas.

AMSOIL Synthetic Stationary Natural Gas Engine Oil should not be used in vehicular applications that run on propane or natural gas.

COMPATIBILITY

AMSOIL Synthetic Stationary Natural Gas Engine Oil is compatible with conventional petroleum oils and other synthetic lubricants; however, mixing AMSOIL Stationary Natural Gas Engine Oil with other oils will shorten the oil’s life expectancy and reduce the performance benefits.

Aftermarket oil additives are not recommended for use with AMSOIL Synthetic Stationary Natural Gas Engine Oil.
