What grade of engine oil is used for the Changan CS95?
2 Answers
Changan CS95 uses 5W40 engine oil. Engine oil is composed of base oil and additives. The base oil is the main component of lubricating oil, determining the basic properties of the lubricating oil. Its functions are: 1. Lubrication and wear reduction; 2. Auxiliary cooling and temperature reduction; 3. Sealing and leakage prevention; 4. Rust and corrosion prevention; 5. Shock absorption and buffering. Taking the 2019 Changan CS95 as an example, its body structure is a five-door seven-seat SUV. The body dimensions are: length 4949mm, width 1930mm, height 1790mm, wheelbase 2810mm, front and rear track 1625mm, fuel tank capacity 74L, and curb weight 2007kg.
For the Changan CS95, I understand that it comes standard with the Blue Whale series engine, and most models recommend using 5W-30 full synthetic oil. This viscosity ensures quick lubrication of components during cold starts, preventing wear, while maintaining stability at high temperatures to protect the turbocharging system. Changan's official manual clearly states that 5W-30 is suitable for China's diverse climate, especially ensuring smooth starts in low-temperature regions. Using the wrong oil, such as a higher viscosity like 10W-40, can increase fuel consumption and even cause engine noise; conversely, oil with too low viscosity can accelerate wear and failure. I recommend prioritizing branded oils like Shell or Mobil, ensuring API or ILSAC certification, and avoiding substandard aftermarket products. Regular oil changes every 5,000-7,500 kilometers or every six months, adjusted according to driving habits, can significantly enhance engine lifespan and fuel efficiency. For frequent long-distance or high-load usage, adding an oil change reminder is a reliable way to ensure peace of mind and maintain performance.
