What type of engine oil is used for Yunnei engines?
2 Answers
Yunnei engines use CI-4 grade engine oil. Below is relevant information about engine oil: 1. Concept: Engine oil, also known as engine lubricating oil. 10W-40 represents the SAE standard viscosity value, which first indicates that this oil is a multi-grade oil. 2. Requirements: As a type of machinery, engines have common requirements for lubricating oil similar to general machinery, such as requiring appropriate viscosity, certain anti-oxidation, anti-wear, anti-corrosion, and viscosity-temperature performance requirements. The general requirements for engines are small size, light weight, compact structure, and high output power, which means the load per unit friction surface is very large.
After driving for so many years, I often use diesel engine oil for Yunnei engines. The official recommendation is usually CH-4 or CI-4 grade oil with a viscosity of 15W-40, which is suitable for heavy-duty engines and helps protect parts from wear. When choosing engine oil, you need to consider the vehicle model and usage environment. For example, thicker oil in hot weather can prevent overheating and carbon buildup. I tried cheaper oil a few times and noticed increased noise and higher fuel consumption, so now I only trust big brands. Changing the oil every 10,000 kilometers or six months is the safest. Also, remember to check the oil level, as low oil levels can accelerate engine aging.
