What kind of oil should be used for the Dongfeng Ax7?

The Dongfeng Ax7 should use 5w-30 full synthetic oil. The engine is the heart of the car, and the oil is the engine lubricating oil that can play a role in lubricating, cleaning, cooling, sealing, anti-corrosion, and reducing friction. The oil code includes two parts, the grading and the viscosity specification. The "W" in the oil code indicates the winter, and the smaller the number before the "W", the better the low-temperature flowability of the oil and the better the protection of the engine in cold start. The number after the "W" (a horizontal line) indicates the indicator of the oil's high-temperature protection performance. The higher the number, the better the protection of the oil in high temperature.

The main functions of engine oil are introduced as follows:

1. Lubrication and reduction of friction: When oil is added to the two sliding parts, it can make the two parts run smoothly without friction.

2. Assist in cooling and heat dissipation: The engine generates high temperature when it runs. The addition of oil can absorb heat and help cool the engine.

3. Cleaning: Oil has good fluidity, which can wash the dirt on the surface of the parts.

4. Sealing and anti-leakage: After adding oil, a seal can be formed between the活塞环 and the活塞, reducing the entry of pollutants.

5. Anti-corrosion and anti-rust: Oil has the ability to adsorb water, air, acid substances, and harmful gases, playing a role in anti-corrosion and anti-rust.

6. Reduce shock: Oil can lubricate the bearing and reduce the impact, playing a buffering role.
