Features & Benefits

• Excellent protection for newer low-emission diesel engines and older diesel engines

• Specially formulated to protect exhaust aftertreatment systems

• Exclusive Liquid Titanium protection additive provides enhanced oxidation resistance and protection against engine wear

• Outstanding soot control for protection against abrasive wear and soot-induced oil thickening

• Outstanding resistance to viscosity and thermal breakdown at high temperatures

• Protects against sludge and varnish formation

• Protects against rust and bearing corrosion

• Excellent low-temperature pumpability with soot-laden oil

• High shear stability

• Good resistance to foaming and aeration


• 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
