Diesel engine oil
Diesel engine oil CK-4 20W50 4L*6PCS
Performance characteristics: Hydrogenation process base oil and imported heavy-duty diesel engine oil compound with low sulfate ash have excellent oxidation resistance and soot treatment ability, which can effectively disperse soot and deposits and keep the engine clean. At the same time, it has good low-temperature starting performance, can provide enough oil film thickness at the moment of low-temperature cold start of the engine to prevent abnormal wear, and has excellent shear stability and thermal stability, which can ensure normal work and reduce oil consumption.

Features
High specification level: API CK-4 is the mainstream high-end specification of heavy-duty diesel engine oil at present. Compared with the previous generation CI-4+,it has significantly improved the performance of wear resistance, oxidation resistance and carbon deposition control, and can better protect high-pressure common rail, EGR (exhaust gas recirculation) and other precision components. Wide viscosity adaptation: 20W-50 is multi-grade viscosity, "20W" means low-temperature starting (normal starting at around -20℃), and "50" means high-temperature viscosity at 100℃, giving consideration to low-temperature easy starting and high-temperature oil film stability, which is suitable for use in most areas all the year round. Long-term protection: excellent alkali value retention (such as the alkali value of 8.91 mg KOH/g in the previous experimental data) can neutralize acidic substances produced by combustion and reduce engine corrosion. Usually, the oil change interval can reach 40,000-60,000 km (depending on the equipment working conditions).
Application
Commercial vehicles: diesel engines of long-distance transport vehicles such as heavy trucks and buses. Construction machinery: excavators, loaders, road rollers and other off-road mobile machinery. Fixed equipment: diesel generator sets, large air compressors and other long-term high-load operation equipment. If you need to compare the indicators of different brands of this type of engine oil, or want to know whether a certain type of equipment is applicable, I can help you further sort out the information.

Grease Usage Notice
Follow the oil change standard: check the oil level and quality regularly according to the requirements of the equipment manual (for example, detect the viscosity and metal wear particle content through oil sample analysis), and do not rely solely on mileage to avoid premature failure of the oil due to poor fuel quality and bad working conditions.
