EL MAR® LA4 EXD
NEXT-GENERATION, LOW-ASH NATURAL GAS ENGINE OIL
Phillips 66® El Mar LA4 EXD is a premium quality, next-generation, low-ash, dispersant-detergent gas engine oil designed for use in high-output 4-stroke cycle and some 2-stroke cycle natural gas engines operating under severe conditions. It is particularly recommended for use in stoichiometric and lean-burn gas engines fueled by natural gas or LPG, which typically are found on crude oil and gas transmission pipelines, electrical power generators, gas compressors, irrigation water pumps and well drilling rigs.

Features & Benefits
- Proven extended-drain capability for reduced maintenance costs and maximum productivity
- Field-proven performance in providing outstanding engine cleanliness
- High dispersancy protects against sludge and varnish formation
- Outstanding resistance to oil oxidation and nitration
- Enhanced protection against piston scuffing and ring and liner wear
- Excellent protection against rust and corrosion
- Low-ash formulation 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
- Turbocharged, lean-burn and naturally aspirated 4-stroke cycle and some 2-stroke cycle natural gas engines where the manufacturer specifies a low ash gas engine oil meeting API CF or API CD performance requirements
- Some gas engines burning landfill gas containing minimal levels of hydrogen sulfide
