What is the CK diesel engine oil grade and model?
2 Answers
CK diesel engine oil grade and model are explained as follows: 1. Grade standard: API introduced the CK-4 grade standard. CK-4 diesel engine oil offers better performance. Using this diesel engine oil ensures good lubrication even in low winter temperatures, preventing starting issues. In high summer temperatures, the oil evaporates less, reducing the need for frequent top-ups. Most importantly, this oil has excellent resistance to deposits, resulting in minimal sludge and carbon buildup even after prolonged use, keeping the engine like new with sufficient power and reduced fuel consumption. 2. Series introduction: When selecting engine oil, it's essential to understand how diesel engine oil grades are classified, as different engines have varying requirements. CK-4 oil is currently the highest oil grade. After the introduction of the CK-4 certification standard, many oil brands began offering corresponding products. The K series includes three products: K6, K8, and K10, with oil change intervals ranging from 60,000 to 100,000 kilometers.
As a diesel truck driver, I frequently handle various diesel engine oils. The API CK grade primarily refers to CK-4, which is the standard engine oil specification for heavy-duty diesel engines set by the American Petroleum Institute. It is particularly suitable for modern emission systems, reducing engine wear, extending component lifespan, and helping control exhaust emissions, making the vehicle run more stably. I've been driving diesel vehicles for twenty years and have always used CK-4 oil. Choosing the right viscosity, such as 15W-40, is crucial. Combined with regular oil changes (e.g., every 8,000 kilometers), it can prevent engine overheating or damage, saving a lot on repair costs. Using the wrong oil grade, such as a lower-grade one, can lead to reduced power and even exceed emission standards. Remember to check the vehicle manual to ensure compatibility—this makes driving safer and more cost-effective, especially highlighting its advantages in long-haul transportation.
