Phillips 66 El Mar LA4 EXD 15W-40

SAE Grade: SAE 15W40
Phillips 66 El Mar LA4 EXD 15W-40 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.

    Detailed Product Description

    El Mar LA4 EXD 15W-40 Gas Engine Oil (GEO) is formulated with high-quality Group II base stocks and the latest, state-of-the art, fi eld-proven additive technology developed to meet the rigorous lubrication demands of modern, fuel-effi cient, low-emission gas engines. It provides outstanding resistance to oil oxidation and nitration, and has a wellbalanced alkaline reserve (TBN) to neutralize acids over long service intervals. It protects against ring and liner wear, minimizes the formation of sludge and piston deposits for outstanding engine cleanliness, and protects against corrosion. It also protects against valve stem deposits and valve recession, resulting in reduced maintenance and extended engine life. The additive package has low phosphorus content to meet the requirements of gas engines equipped with catalysts for exhaust after-treatment.

    El Mar LA4 EXD GEO has demonstrated the capability to extend oil service intervals without compromising engine performance or component life. The use of high-quality, low-volatility base stocks helps reduce oil consumption, minimize exhaust system deposits and reduce the amount of make-up oil needed, thereby resulting in lower operating costs.
