BONNEY™ CK-4 15W40

Description

Bonney Lubricants CK-4 15W40 is a premium heavy-duty diesel engine oil formulated with advanced synthetic technology base oils, designed for severe-duty, high-speed four-stroke diesel engines, including those equipped with diesel particulate filters (DPFs), cooled exhaust gas recirculation (EGR), and other exhaust treatment systems. Suitable for both turbocharged and naturally aspirated engines, it meets API CK-4 specifications and is compliant with Euro I through VI emission standards. This oil offers superior durability and protection through enhanced shear stability, reduced oxidative thickening, and minimized abrasive wear, bore polishing, and piston deposits. It is backwards compatible with applications requiring API CJ-4, CI-4 Plus, CI-4, and CH-4 specifications and is suitable for 2017 model vehicles and beyond, delivering improved performance over CJ-4 oils.

Applications:

Recommended for high-speed four-stroke diesel engines in heavy-duty vehicles, including those with DPFs, cooled EGR, and other exhaust treatment systems. Suitable for turbocharged and naturally aspirated engines in commercial trucks, construction equipment, and other heavy-duty applications meeting Euro I-VI emission standards. Always consult your vehicle’s manual to ensure compatibility.
