COPTON CK-4
Diesel engine Oil
Light-duty series
Synthetic Technology
RECOMMENDED APPLICATIONS
Meets China National VI b & below emission standards
Low SAPS formulation protects aftertreatment systems (DPF included) from clogging and optimizes efficiency.
Fuel Saving
Excellent low-temperature fluidity reduces cold-start wear and improves fuel economy.
Higher Power, Cleaner Engine, Superior Protection
2nd-Gen Pressure Balancing Technology: fully synthetic base stocks + imported additives deliver stable oil pressure and sustained power.
Superior oxidation stability slows oil degradation and extends drain intervals.
10 TBN high base reserve prevents acidic corrosion to safeguard engines.
Detergency & dispersancy up 48%* to minimize sludge and deposits.
* Based on standard engine bench tests versus API CK-4 limits.
