ConocoPhillips has introduced a “next generation premium low ash natural gas engine oil” called EL MAR LA4EXD, and has added a “mainline low ash product” called EL MAR Low Ash to its line of Conoco natural gas engine oil offerings. Formulated to meet the increased performance demands of today’s high-output natural gas engines, the new Conoco oils are designed to enable engines to operate smoothly at maximum efficiency, protecting the hardware, and minimizing downtime, while also improving the bottom line by reducing operational expenses, said the company.

“Operators who use our new EL MAR LA4 EXD formulation stand to benefit from enhancements in wear reduction, engine parts cleanliness, valve recession control and ability for extending oil drain service,” said Reginald Dias, director, Commercial Products, ConocoPhillips. “In fact, both the EL MAR LA4EXD and the EL MAR Low Ash [products] have passed extensive field tests, and performed extremely well under the most severe conditions, ultimately keeping engines clean and running at optimal levels.”

Dias said EL MAR LA4EXD is a premium quality, low ash dispersant-detergent gas engine oil designed for use in four-stroke cycle engines fueled by natural gas or LPG. Formulated with unique, next-generation additive technology, it combines the advantages of high-quality group II base stocks and a field-proven performance additive to provide excellent engine cleanliness, deposits control, and wear and corrosion reduction. He said the new technology further advances ability for extended oil drain service already established by the earlier EL MAR LA4 technology. In field testing, the new EL MAR LA4EXD formulation outperformed the earlier EL MAR LA4, which in turn had already excelled against a leading competitor at most inspection points in a matching test, according to Dias. EL MAR LA4EXD shows better engine cleanliness, less deposits on critical parts, reduced wear and corrosion, and better resistance to oil oxidation under extended drain conditions, he added, and the new low ash technology helps to protect emissions control devices such as catalytic converters and exhaust after-treatment from fouling from high ash or catalyst poisons.

EL MAR LOW ASH offers excellent oxidation and nitration control, reduced valve seat recession and enhanced engine cleanliness, said Dias. These features help to prevent or minimize problems such as exhaust valve recession, guttering, deposits formation and plug fouling, common to natural gas engines operating under adverse conditions. He said 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.
