EL MAR® ASHLESS HEAVY DUTY GEO
ASHLESS NATURAL GAS ENGINE OIL
Phillips 66® El Mar Ashless Heavy Duty GEO is a high-quality engine oil designed for naturally aspirated and moderately turbocharged two-stroke natural gas engines like those commonly used in crude oil and gas transmission pipelines, power generators, gas compressors, irrigation pumps, and well drilling rigs.
Formulated with field-proven performance additives, El Mar Ashless Heavy Duty GEO meets the demanding lubrication needs of modern, fuel-efficient, low-emission gas engines. It resists oxidation and nitration, protects against ring and liner wear, minimizes sludge and piston deposits for superior engine cleanliness, and guards against corrosion.
Its ashless formulation keeps intake ports clean to maintain peak engine performance and extends spark plug life in spark-ignited gas engines.
