Phillips 66 Firebird Heavy Duty EC 15W40

SAE Grade: SAE 15W40
Phillips Firebird Heavy Duty EC (Emission Compatible) Diesel Engine Oil is an API CJ-4 engine oil developed for use in four-stroke cycle diesel engines designed to meet 2007 and later EPA on-highway exhaust emissions standards. It is specially formulated for compatibility with exhaust aftertreatment systems using diesel particulate fi lters (DPFs), diesel oxidation catalysts (DOCs) and/or selective catalytic reduction (SCR).It is backward serviceable for use in pre-2007 diesel engines, and may be used in mixed fl eets with both diesel and gasoline-fueled vehicles.

    Detailed Product Description

    Firebird Heavy Duty EC is formulated with a blend of high-quality conventional and re-refi ned base stocks. It has excellent soot dispersancy to protect against soot-induced oil thickening and abrasive wear, and excellent oxidation resistance to help minimize deposit formation. The low-ash formulation protects exhaust catalysts on low-emission engines and helps prolong DPF life. The use of rerefi ned base stocks helps lessen the environmental impact of disposal of used oil.

    Firebird Heavy Duty EC meets or exceeds the performance requirements of API Service Categories CJ-4 and SM as well as leading OEM specifi cations for use in low-emission diesel engines. It is backward serviceable for use where earlier API “C” category engine oils, or the concurrent earlier OEM specifi cations, are specifi ed. It is formulated for use in diesel engines operating on diesel fuels with sulfur content up to 500 ppm. However, for applications not using Ultra-Low Sulfur Diesel (ULSD), consult the engine manufacturer for recommended service interval.
