ConocoPhillips formulated both its EL MAR LA4EXD premium low-ash natural-gas engine oil and EL MAR LOW ASH, a mainline low ash product, to meet the increased performance demands of today’s high-output natural gas engines. EL MAR LA4EXD is a dispersant-detergent gas engine oil designed for use in four-stroke cycle engines fueled by natural gas or liquid propane gas (LPG). Formulated with next-generation additive technology, it combines the advantages of high-quality group II base stocks and an upgraded performance additive to facilitate excellent engine cleanliness, deposits control and reduced wear and corrosion, while advancing the ability for extended oil drain service. The new low ash technology also helps to protect emissions-control devices such as catalytic converters and exhaust afterreatment from fouling from high ash or catalyst poisons.

EL MAR LOW ASH offers added oxidation and nitration control, reduced valve seat recession and enhanced engine cleanliness, helping to prevent or minimize problems such as exhaust valve recession, guttering, deposits formation and plug fouling, all of which are common to natural gas engines operating under adverse conditions. EL MAR LOW ASH is recommended for use in all naturally aspirated and turbocharged gas engines requiring low ash engine oil, such as Caterpillar, Waukesha Dresser Rand and other four-stroke cycle natural gas engines. The low ash formulation is compatible with catalytic converters and other exhaust aftertreatment devices installed in modern gas engines for emissions control.
