Natural Gas Engine Oils

Formulated engine oils specifically designed for natural gas fueled engines meeting various industry and OEM specifications.

SPX Endurance Ashless NGEO 30, 40, 15W-40

SPX Endurance Ashless NGEO is an ashless, dispersant detergent gas engine oil for use in naturally aspirated and turbocharged 2-stroke cycle natural gas engines. Engines operating in this type of service typically are found on crude oil and gas transmission pipelines, electrical power generators, gas compressors, irrigation water pumps, and well drilling rigs.

Advantages
• Ashless formulation helps minimize port deposits
• High dispersancy protects against sludge and varnish formation
• Excellent resistance to oxidation and nitration• Protects against scuffing and wear
• Protects against rust and corrosion• Does not contain any bright stock, which can cause harmful carbon deposits

Applications
• 2-stroke cycle and some 4-stroke cycle natural gas engines where the manufacturer specifies an ashless gas engine oil

SPX Endurance Ashless NGEO is recommended for use in natural gas engines manufactured by the following OEMs:
o Ajax
o Climax
o Colt-Fairbanks Morse
o Cooper-Bessemer
o Dresser Clark
o Dresser Rand (Category I, II)

SPX Endurance Low Ash NGEO 40

SPX Endurance Low Ash GEO is a premium quality, low-ash, dispersant-detergent gas engine oil for use in high-output 4-stroke cycle natural gas engines operating under heavy loads and extreme temperatures. Engines operating in this type of service typically are found on crude oil and gas transmission pipelines, electrical power generators, gas compressors, irrigation water pumps, and well drilling rigs. SPX Endurance Low Ash GEO is formulated with high quality Group II base stocks and field proven additive technology developed to meet the lubrication demands of modern, fuel-efficient, low-emission gas engines. The formulation protects against ring and liner wear and valve stem deposits as well as valve recession, resulting in reduced maintenance and extended engine life. The additive package has a low phosphorus content to meet the requirements for gas engines equipped with exhaust after-treatment systems.

Advantages
• Field-proven performance in providing outstanding engine cleanliness
• Low-ash formulation helps protect against valve stem deposits and valve recession
• High dispersancy protects against sludge and varnish formation
• Excellent resistance to oxidation and nitration
• Premium protection against scuffing and wear
• Premium protection against rust and corrosion
• Compatible with emissions system catalysts
• Does not contain any bright stock, which can cause harmful carbon deposits

Applications
• Turbocharged, lean burn and naturally aspirated 4-stroke cycle natural gas engines where the manufacturer specifies a low-ash gas engine oil meeting API CF performance requirements
• Some gas engines burning landfill gas containing minimal levels of hydrogen sulfide

SPX Endurance Low Ash GEO is recommended for use in natural gas engines manufactured by the following OEMs:
o Caterpillar
o Cummins
o Dresser Rand
o Guascor
o Jenbacher
o MAN Diesel & Turbo 4T
o MTU
o MWMo Niigata

SPX Endurance XD Low Ash NGEO 40

SPX Endurance XD Low Ash GEO is a premium quality, low-ash, dispersant-detergent gas engine oil for use in high-output 4-stroke cycle natural gas engines operating under severe service conditions. It is recommended for use in stoichiometric and lean-burn gas engines fueled by natural gas or LPG, which typically are found on crude oil and gas transmission pipelines, electrical power generators, gas compressors, irrigation water pumps, and well drilling rigs. SPX Endurance XD Low Ash GEO is formulated with high quality Group II base stocks and field proven additive technology developed to meet the lubrication demands of modern, fuel-efficient, low-emission gas engines. The formulation has a well-balanced alkaline reserve (TBN) to neutralize acids over long service intervals. It protects against ring and liner wear and valve stem deposits as well as valve recession, resulting in reduced maintenance and extended engine life. The additive package has a low phosphorus content to meet the requirements for gas engines equipped with exhaust after treatment systems. The use of high quality, low volatility base stocks helps reduce oil consumption, minimize exhaust system deposits and reduce the amount of make-up oil needed.

Advantages
• Proven extended-drain capability for lower maintenance costs and maximum productivity
• Field-proven performance in providing outstanding engine cleanliness
• Low-ash formulation helps protect against valve stem deposits and valve recession
• High dispersancy protects against sludge and varnish formation
• Excellent resistance to oxidation and nitration
• Superior protection against scuffing and wear
• Superior protection against rust and corrosion
• Compatible with emissions system catalysts
• Does not contain any bright stock, which can cause harmful carbon deposits

Applications
• Turbocharged, lean burn and naturally aspirated 4-stroke cycle natural gas engines where the manufacturer specifies a robust low-ash gas engine oil meeting API CF performance requirements
• Some gas engines burning landfill gas containing minimal levels of hydrogen sulfide

SPX Endurance XD Low Ash GEO is recommended for use in natural gas engines manufactured by:
o Caterpillar
o Cummins
o Dresser Rand
o Guascor
o Jenbacher
o MAN Diesel & Turbo 4T
o MTU
o MWM
o Niigata
