Changan Automobile uses Shell engine oil as the original oil for its entire range. This well-established brand offers relatively high cost performance. Introduction to engine oil: Engine oil, also known as engine lubricant (English name: Engine-oil), serves multiple functions for engines including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of automobiles. Composition of engine oil: Engine oil consists of two main components: base oil and additives. The base oil forms the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics. Additives are an essential component of lubricating oil.

As a seasoned driver with over a decade of experience, my Changan Eado uses original Castrol engine oil, which I recall is a 5W-30 synthetic type. The viscosity is just right, providing solid engine protection. Choosing the right oil is crucial—it reduces friction and wear, extending engine life. Oil changes are typically done every 5,000 to 7,500 kilometers. I always check the manual for specific requirements or visit authorized 4S shops for oil changes to maintain warranty validity. Don't cut corners with cheap, off-brand oils. Dirty oil also means replacing the filter to keep things clean. Proper maintenance ensures smooth and hassle-free driving.

After spending a long time in the repair shop, I've seen many issues with the original oil of Yidong cars. Most of them use Castrol's 5W-30 fully synthetic oil, but the specific type should be checked in the manual as the brand may vary by year. Choosing the right oil can control noise and save fuel; otherwise, the engine is prone to overheating and malfunctions. Don't be careless when changing oil—extending the interval to 10,000 kilometers requires pairing it with filter cleaning for minor maintenance. For lazier car owners, regular checks at the 4S shop for oil levels make maintenance simple and worry-free. The manual or manufacturer hotline can help confirm the brand—don't rely on online rumors.

For beginners just starting with the Yidong, checking the maintenance manual shows the original recommended oil is Castrol 5W-30 synthetic, a brand that matches the engine well. Choosing the right oil ensures engine durability and smooth daily driving. The oil change interval is around 7,500 km—remember to check the dipstick and not exceed the upper limit. The manual clearly lists everything, making it easy to reference for follow-up maintenance. I’ve also learned basic checks to prevent contamination. Changing oil and filters on time saves money and hassle, ensuring smooth starts and stops without shaking.
