EL MAR® MID ASH SUPREME GEO

MID-ASH NATURALGAS ENGINE OIL

Phillips 66® El Mar Mid Ash Supreme GEO is a premium quality, mid-ash, dispersant-detergent gas engine oil designed for use in naturally aspirated and moderately to highly turbocharged 4-stroke cycle natural gas engines. It is particularly recommended for use in natural gas engines and dual-fuel engines burning sour gas or landfill gas.

EL MAR® MID ASH SUPREME GEO

Features & Benefits

  • 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

Applications

  • 4-stroke cycle gas and dual-fuel engines burning sour gas or landfill gas
  • 4-stroke cycle gas engines in wastewater treatment plants fueled by digester gas
  • 4-stroke cycle converted irrigation engines running on natural gas or LPG
  • Other 4-stroke cycle natural gas engines where the manufacturer specifies a mid-ash gas engine oil
