Guardol Eco™ Diesel Engine Oil (Firebird®)

Phillips 66® Guardol Eco Diesel Engine Oil, formerly known as Firebird Heavy Duty EC, is an environmentally responsible API CK-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 filters (DPFs), diesel oxidation catalysts (DOCs) and/or selective catalytic reduction (SCR). It is backward serviceable for use in pre-2007 diesel engines. Features & Benefits

• Excellent protection for newer low-emission diesel engines and older diesel engines
• Specially formulated to protect exhaust aftertreatment systems
• Protects against particulate filter plugging
• Excellent soot control for protection against abrasive wear and soot-induced oil thickening
• Excellent resistance to viscosity and thermal breakdown at high temperatures
• Protects against sludge and varnish formation
• Protects against rust, bearing corrosion and wear
• Good resistance to foaming and aeration
• Lessens the environmental impact of used oil disposal

Applications

• On-highway diesel trucks equipped with EGR and exhaust aftertreatment systems to meet 2007/2010 emissions standards
• Older diesel equipment with conventional, non-EGR engines or ACERT engines
• Off-highway construction, earth moving and mining equipment
