What type of engine oil should be used for the Changan CS55plus?
2 Answers
Changan CS55plus can use Shell HX7 5w-40 synthetic engine oil. Introduction to engine oil: Engine oil, also known as engine lubricant, has a density of approximately 0.91kg×10³. It 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. It is often referred to as the 'blood' of automobiles. Under such demanding operating conditions, only qualified lubricating oil can reduce wear on engine components and extend their service life. Composition of engine oil: 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. 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.
I think the Changan CS55 Plus is generally recommended to use 5W-30 full synthetic engine oil, as this grade adapts to various temperatures, ensuring smooth starts in winter and strong protection in summer. When I drive this car myself, I always follow the manual and use this type, with good results. The 5W indicates low-temperature fluidity, suitable for most regions in China; the 30 represents high-temperature viscosity, protecting the engine from wear under high temperatures. Synthetic oil is more durable than mineral oil, allowing the oil change interval to be extended to 7,500–10,000 km. Don’t casually switch to 0W-20—if it’s incompatible, it may lead to increased fuel consumption or excessive noise. Remember to regularly check the oil level, ensuring it stays between the min-max marks. Proper maintenance can help avoid major repair troubles.
