Laboratory tested and field proven in extreme operating conditions.
Extended drain capability reduces maintenance costs.
Keeps engines cleaner for longer service life.
Helps meet emission standards while protecting aftertreatment systems.
API CH-4 is a high-performance diesel engine oil specification designed for high-speed, four-stroke engines. It provides excellent wear protection, soot control, and thermal stability, meeting the emissions standards of modern diesel engines.
Yes. API CH-4 specifications are specifically engineered to provide enhanced protection for turbocharged engines as well as engines equipped with Exhaust Gas Recirculation (EGR) systems operating under heavy-duty loads.
It contains advanced detergent and dispersant additives that prevent the accumulation of sludge, varnish, and carbon deposits on pistons, even in high-soot environments, ensuring smooth oil flow and longer engine life.
Yes. Thanks to its strong TBN (Total Base Number) retention, the oil effectively neutralizes acidic byproducts generated during combustion, allowing for extended change intervals and reduced overall maintenance costs.
API CH-4 engine oil is commonly available in three major viscosity grades: 15W-40, 10W-30, and 20W-50, designed to provide optimal flow and lubrication performance across a wide range of operating temperatures and environments.
