EL MAR® LF-D GEO

PREMIUM, NEXT-GENERATION GEO FOR LANDFILL AND DIGESTER FUEL

Phillips 66® El Mar LF-D (Landfill-Digester) GEO is a premium low-ash gas engine oil specifically designed for landfill gas applications. It excels at controlling silica deposits caused by the combustion of siloxane gases commonly found in landfills.

Combining high-quality base stocks with superior silica deposit controls helps El Mar LF-D GEO lower oil consumption.

Formulated with high-quality Group II base stocks and advanced high-dispersant additive technology, El Mar LF-D GEO meets the demanding lubrication needs of natural gas engines running on landfill or digester fuel. It offers excellent resistance to oxidation and nitration while maintaining a balanced alkaline reserve (TBN) to neutralize acids over extended service intervals. The oil protects against ring and liner wear and minimizes silica buildup on cylinder heads and liners for cleaner, more efficient operation.

This oil’s zinc and phenate-free additive package ensures compatibility with landfill applications, while its low ash content safeguards catalysts and exhaust aftertreatment systems. With this advanced formulation, cylinder heads and other critical engine parts can expect an extended life, which reduces maintenance requirements and overall costs.
