The D1 specification and COPTON CK-4 diesel oils
COPTON helped develop China's first national diesel engine oil specification.
China has released D1 — the first national diesel engine oil specification with fully domestic intellectual property.
As a core member of the China Engine Oil Standard Development Alliance (CLSAC), COPTON took part in the work: over 60,000 hours of bench tests, 3,300 tonnes of fuel and more than 30 technical challenges solved.
COPTON API CK-4 diesel oils are built for modern diesels, including Chinese-made engines — in our catalog these are NANO Supreme, G6 and the light-duty oils.
