Conoco® El Mar LA4 EXD is a premium quality, next-generation, low-ash, dispersant-detergent gas engine oil designed for use in high-output 4-stroke cycle and some 2-stroke cycle natural  gas engines operating under severe conditions. It is particularly 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.
El Mar LA4 EXD is formulated with high-quality Group II base stocks and the latest, state-of-the art, field-proven additive technology developed to meet the rigorous lubrication demands of modern, fuel-efficient, low-emission gas engines. It provides outstanding resistance to oil oxidation and nitration, and has a well-balanced alkaline reserve (TBN) to neutralize acids over long service intervals. It protects against ring and liner wear, minimizes the formation of sludge and piston deposits for outstanding engine cleanliness, and protects against corrosion. It also protects against valve stem deposits and valve recession, resulting in reduced maintenance and extended engine life. The additive package has low phosphorus content to meet the requirements of gas engines equipped with catalysts for exhaust after-treatment.
