NATIONAL PERFOMAX ULTRA HDX10SAE 10W-40 API CK-4

National Perfomax Ultra HDX10 is an EC (Emission Compatible) Diesel Engine Oil specially developed to meet the requirement of API CK-4 performance level. It is designed to meet 2007 and later on-highway exhaust emissions standards. It is formulated with superior base oils fortified with a finely balanced additive package that ensures the robust performance required by modern diesel engines. It is compatible with exhaust after treatment systems using diesel particulate (DPFs), diesel oxidation catalysts (DOCs) and/or selective catalytic reduction (SCR) units. It is backward serviceable for use in pre-2007 diesel engines.

Benefits

• Helps extend oil drain intervals (ODI) in conjunction with OEM recommendations.
• Fully backward compatible with previous level CJ-4, CI-4 Plus, CI-4 and prior API performance levels.
• Provide excellent soot control and retention of TBN and shear stability.
• Well suited for higher millage engines and for mixed fleets where older and newer vehicles can all use the same oil.
• Improved engine cleanliness and protection against deposit formation in pistons.
• Extends the life of critical wear surfaces, gaskets and seal materials.

Applications

This oil is well suited for use in construction, mining and agricultural applicants where ultra-low Sulfur diesel fuels are being run on equipment employing low emissions technology including EGR (Exhaust Gas Recirculation), SCR (Selective Catalytic Reduction) and DPF (Diesel Particulate Filtration). It is designed for use when extended drain intervals are designed as well as where extreme operating conditions may exist. Formulated to handle today’s heavy-duty turbocharged diesel engines as well as naturally aspirated models.
