Phillips 66® El Mar Low Ash is a premium quality, low-ash, dispersant-detergent gas engine oil designed for use in high-output, 4-stroke cycle natural gas engines operating under heavy loads and extreme temperatures. Engines operating in this type of service typically are found on crude oil and gas transmission pipelines, electrical power generators, gas compressors, irrigation water pumps and well drilling rigs.
• Field-proven performance in providing outstanding engine cleanliness
• Proven performance in lean-burn engines
• High dispersancy protects against engine sludge and varnish deposits
• Excellent resistance to oil oxidation and nitration
• Protects against scuffing and wear
• Protects against rust and corrosion
• Protects against valve stem deposits and valve recession
• Compatible with emissions system catalysts
• Does not contain any bright stock, which can cause harmful carbon deposits
• Turbocharged, lean-burn and naturally aspirated 4-stroke cycle natural gas engines where the manufacturer specifies a low-ash gas engine oil meeting API CD performance requirements
