EL MAR® LOW ASH SHIELD® GEO
Phillips 66® El Mar Low Ash Shield is a low-ash, dispersant-detergent gas engine oil designed for use in high-output, 4-stroke cycle natural gas engines in compression service utilizing sweetening systems where the engine crankcase lubricant is used to lubricate the compressor cylinders.
El Mar Low Ash Shield is formulated with field-proven performance additives to meet the rigorous lubrication demands of modern, fuel-efficient, low-emission gas engines. It protects against ring and liner wear, helps minimize engine 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.
