Should Wuling use 30 or 40 engine oil?
2 Answers
Wuling vehicles can use 30 viscosity engine oil. 40 viscosity engine oil is too high for Wuling engines. Relevant information is as follows: 1. Engine oil not only lubricates the engine but also cleans, seals, buffers, prevents rust, and dissipates heat. 2. When the engine is running, engine oil forms a film on the surface of various components inside the engine, preventing direct contact and friction between them. 3. All performance aspects of engine oil degrade over time, so it needs to be replaced regularly.
I've driven Wuling vehicles for several years and have flipped through the user manual many times. It consistently recommends using 10W-30 oil. This viscosity is particularly suitable for small-displacement engines, ensuring quick cold starts in winter and reducing engine strain. During summer heat, it doesn't thin out excessively, maintaining proper lubrication. Always check the manual for specific models, as different Wuling vehicles like the Hongguang or Rongguang may have slight variations. Regular oil changes are crucial—I use full synthetic oil and change it every 5,000 kilometers, which saves money and hassle. Otherwise, sludge buildup can wear out components. Avoid casually using 40-weight oil; while it's thicker at high temperatures, it causes slower cold starts and potential engine damage. Maintaining this habit results in fewer issues even as the vehicle ages.
