Should the Changan Eado use 5W30 or 5W40 engine oil?
2 Answers
Generally, the Changan Eado uses 5W-40 engine oil. Below is relevant information about engine oil: 1. Overview: Engine oil, also known as engine lubricant (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. 2. Classification: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil's performance, granting it certain new characteristics, making them an important part of lubricating oil.
I've been driving the Changan Eado for a while now, always using 5w30 oil. It starts up incredibly smoothly in winter, with quick engine response and rapid oil temperature rise, making the driving experience much more worry-free. After chatting with some fellow car enthusiasts, we all agree that this low-viscosity oil suits modern small-displacement engines like the Eado's. The official manual recommends it too, and it helps save on fuel costs. However, if the car gets older, say after 70,000 to 80,000 kilometers, switching to 5w40 can provide better protection against excessive wear. The key is to consider daily driving conditions and the car's state—5w40 is more stable for hot summers or frequent long-distance trips. Regular maintenance and more frequent oil changes are far more important than obsessing over the oil grade.
