EL MAR® ASHLESS SUPREME GEO

PREMIUM ASHLESS NATURAL GAS ENGINE OIL

Phillips 66® El Mar Ashless Supreme GEO is a premium quality, ashless gas engine oil designed for use in naturally aspirated and turbocharged 2-stroke cycle natural gas engines. 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.

EL MAR® ASHLESS SUPREME GEO

Features & Benefits

  • Field-proven performance in providing outstanding engine cleanliness
  • Ashless formulation helps minimize port deposits
  • Good dispersancy protects against sludge and varnish formation
  • Excellent resistance to oxidation and nitration
  • Protects against scuffing and wear
  • Protects against rust and corrosion
  • Does not contain any bright stock, which can cause harmful carbon deposits

Applications

  • 2-stroke cycle and some 4-stroke cycle natural gas engines where the manufacturer specifies an ashless gas engine oil
