Diesel engine oil
Diesel engine oil CK-4 5W40 4L*6PCS
CK-4 5W40 is a high-end lubricant for heavy-duty diesel engines. Its core advantages lie in meeting the emission standards of National VI and above, as well as offering strong anti-wear, anti-oxidation and high-temperature stability. It is suitable for diesel trucks, construction machinery and other equipment.

Features
• Anti-wear protection: Containing high-performance additives, it can form a tough oil film on key components such as pistons and crankshafts, effectively coping with the impact loads caused by the high compression ratio of diesel engines (typically 16:1 - 22:1).
• Anti-high-temperature oxidation: It is less likely to produce sludge and carbon deposits during long-term operation (such as long-distance transportation by trucks), maintaining the cleanliness of the engine oil and extending the engine's lifespan. Environmental compatibility: Compatible with the SCR (Selective Catalytic Reduction) and DPF systems for National VI emission standards, it will not react with urea or exhaust gas treatment agents, thus avoiding system malfunctions.

Application
• Compatible vehicle models: Heavy-duty trucks (such as Dongfeng and Jiefang), medium-duty trucks, pickup trucks, and diesel-powered construction machinery like excavators and loaders that meet National V and VI emission standards.
• Not suitable for: Gasoline engines and light-duty diesel engines (such as some small diesel generators). These types of equipment are more suitable for dedicated engine oils.

Grease Usage Notice
Strictly match engine type: Only for heavy-duty diesel engines (such as trucks, construction machinery). Do not add to gasoline engines or light-duty diesel engines (such as small generators), otherwise it will lead to lubrication failure and component wear. Pay attention to low-temperature usage restrictions: "5W" indicates that it can be started at a minimum temperature of -30℃. If the local temperature is lower than -30℃, a lower viscosity grade (such as 0W40) engine oil should be used to avoid poor fluidity of the engine oil at low temperatures, resulting in difficult starting and delayed lubrication.
