1. copaci uses Quansynthetic engine oil, model 5W-30 or 0W-40. Quansynthetic engine oil is a high-grade engine oil with good lubrication effect.

2. Generally, the oil change in copaci is about 4 liters and 5,000 kilometers. If it is used in synthetic engine oil, it can provide comprehensive protection for the engine, reduce wear and reduce fuel consumption.

3. Engine oil can play the role of lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust prevention and corrosion prevention, and shock absorption and buffering.

4. Choosing the right engine oil can better protect the lubricity of engine oil: under various conditions, engine oil can reduce friction, slow down wear and prevent metal sintering.

5. Low-temperature performance of engine oil: it is called low-temperature operability of engine oil to ensure that the engine can be easily started and reliably supplied with oil at low temperature.
