 Kerryde CH-4 diesel engine oil is made of imported base oils of two or three kinds and imported composite additives. It has super high temperature cleanliness, reduces carbon deposition and sludge deposition, excellent wear resistance, avoids engine parts wear, excellent high temperature oxidation resistance, inhibits oxidation deterioration of oil products and prolongs oil exchange. Oil cycle, good alkali value retention and strong corrosion resistance, provide comprehensive lubrication for the engine. The quality grade of CH-4 diesel engine oil conforms to API classification in the United States.

Product characteristics:


Excellent anti-wear and anti-corrosion can thoroughly solve the wear and corrosion problem of diesel engine under the condition of high soot caused by the use of two-stage bimetallic piston, high pressure direct injection, delayed injection and other advanced technologies.


Excellent high temperature cleanliness and thermal stability can effectively inhibit the formation of piston deposits and maintain high engine cleanliness.


Excellent oxidation stability and dispersion can effectively prevent oil from excessive viscosity increase under high soot conditions.


Excellent foam resistance, can quickly eliminate bubbles in oil products, and ensure the normal lubrication of oil.


Very low volatility and excellent fuel economy;


Production varieties:


Available 5W-30, 10W-30, 10W-40, 15W-40 grades


Matters needing attention:


This product can be used interchangeably with API CH-4 oil of the same viscosity grade of domestic and foreign oil companies, but it can not be mixed.


Recommended oil change cycle:


Under normal vehicle conditions, road conditions and harsher driving conditions, the recommended oil change period is 25,000 km.


Scope of application: Two-stage bimetallic piston, direct injection turbocharged intercooled diesel engine, especially bulldozers, excavators, mining equipment and generators for large-scale overloaded container transport vehicles and working under various harsh conditions, are suitable for domestic and foreign automobile factories. It can replace CF-4 grade oil products.
