What kind of engine oil does the Changan CS55 use?
2 Answers
Changan CS55 uses 5w-40 synthetic engine oil. More information about engine oil is as follows: 1. The engine is the heart of a car, containing many metal parts that move against each other in friction. These components operate at high speeds, in harsh environments, and under elevated temperatures. 2. Engine oil serves to lubricate and reduce wear, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. 3. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties. Additives compensate for and improve the shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricating oil. 4. Different grades of lubricating oil must not be mixed in the Changan CS55. The use of engine oil additives or other engine maintenance products is strictly prohibited, as they may damage the engine under certain circumstances and affect the warranty. Do not use engine oil that does not meet specifications and requirements, as it may lead to increased fuel consumption, reduced power, or even engine damage, affecting the warranty. Replace the engine oil and oil filter at the intervals or mileage specified in the manual to ensure optimal driving experience and engine longevity.
I've been working with engine oil for years, and for the Changan CS55, I recommend using a 5W-30 full synthetic oil. Its engine design is relatively modern, and this viscosity match ensures more balanced lubrication. Synthetic oil performs stably under both high and low temperatures, reducing wear and extending service life. The API standard recommends SP-grade oil, which can handle carbon buildup issues and improve fuel efficiency. The replacement interval is generally every 5,000 to 10,000 kilometers, depending on driving habits and road conditions. If you frequently drive on highways or in cold regions, synthetic oil provides excellent antifreeze performance. Avoid using other viscosities randomly, such as 10W-40, which may be too thick, leading to difficult starts or increased fuel consumption. In short, refer to the owner's manual for brand selection—options like Mobil or Shell are good choices—to ensure smooth engine operation.
