What type of engine oil should be used for Changan CS55?
2 Answers
Changan CS55 uses 5W-40 synthetic engine oil, with an oil filling capacity of approximately 4 liters. Engine oil serves multiple functions for the engine, including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption and cushioning. It is often referred to as the "blood" of a car. Here is more information about automotive engine oil: 1. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. 2. Additives are used to compensate for and improve any deficiencies in the base oil's performance, as well as to impart certain new characteristics, making them an essential part of lubricating oil.
The Changan CS55 typically recommends using 5W-30 full synthetic engine oil, as I've learned from the user manual and practical driving experience. Having driven this car for three to four years, I consistently stick to this grade—it ensures quick starts in winter and stable performance in summer. The engine design is optimized for this viscosity grade, effectively protecting components from wear. I change the oil every 8,000 kilometers, checking the oil level during the process to prevent leaks. For those living in extremely cold regions like Northeast China, considering a 0W series might be advisable, though 5W-30 offers broad compatibility. Always choose reputable brands like Mobil or Shell for reliable quality. Avoid cutting corners with low-grade oils, as they can lead to increased engine noise and higher fuel consumption. Regular maintenance extends the vehicle's lifespan and ensures peace of mind while driving.
