EL MAR® LOW ASH
LOW-ASH NATURAL GAS ENGINE OIL
Phillips 66® El Mar Low Ash GEO is a premium low-ash gas engine oil designed for high-output, four-stroke natural gas engines operating under heavy loads and extreme temperatures. These engines are commonly used in crude oil and gas transmission pipelines, power generation, gas compression, irrigation systems, and well drilling operations.
Formulated with field-proven performance additives, El Mar Low Ash GEO meets the demanding lubrication needs of modern fuel-efficient, low-emission gas engines. It offers excellent resistance to oxidation and nitration, protects rings and liners from wear, and minimizes sludge and piston deposits for superior engine cleanliness to help guard against corrosion and ensure reliable performance even in harsh conditions. By protecting your engine, this oil helps reduce maintenance requirements and extends engine life.
El Mar Low Ash GEO is designed with a low-phosphorus additive package to ensure compatibility with gas engines equipped with exhaust catalysts for aftertreatment.
