Changan CS35 engine uses 5w30 engine oil. This type of oil has good lubrication effect and strong low-temperature fluidity, making it one of the commonly used engine oil types in the market. Engine oils are divided into mineral oil, semi-synthetic oil, and full synthetic oil, each with its own advantages and disadvantages. It is recommended to use semi-synthetic or full synthetic oil as much as possible to ensure better engine performance. The Changan CS35 comes standard with features such as parking sensors, power windows, and LCD displays, while higher-end models may include features like a sunroof, automatic air conditioning, and a multifunctional leather steering wheel. The Changan CS35 demonstrates strong competitiveness in terms of configuration, launching a powerful offensive in economy, practicality, and features.

The Chang'an CS35's engine performs best with 5W-30 full synthetic oil, which is the manufacturer-recommended viscosity grade that provides balanced protection across different temperatures. From my experience, synthetic oil offers better durability, extending engine life by approximately 10%-20%, making it particularly suitable for frequent starts in urban driving conditions. Remember to change the oil regularly every 5,000 kilometers or six months, otherwise sludge buildup may cause engine issues. Chang'an's maintenance manual emphasizes using oil that meets API SN or SP specifications, and advises against arbitrarily switching to other viscosity grades to prevent insufficient lubrication and accelerated wear. If you notice increased engine noise or higher fuel consumption, it likely indicates incorrect oil selection and requires immediate inspection. In summary, diligent maintenance is key to keeping your vehicle running longer.

When choosing engine oil for the CS35, I prioritize cost-effectiveness and find that 5W-30 semi-synthetic or synthetic oils offer the best value. Standard brands like Shell's conventional version are perfectly suitable, costing a few hundred yuan per bottle—avoid cheap, low-quality products to save small amounts but risk major losses. The key is regular oil changes: replace it every 5,000 kilometers to prevent engine issues and avoid higher repair costs. With this approach, my car maintains a stable fuel consumption of around 7L, extending engine life while saving fuel. Using thicker 10W-40 oil in urban traffic can lead to poor lubrication and increased fuel consumption. When changing the oil yourself, always check the dipstick level to ensure it's between the upper and lower limits, avoiding spills and waste. Keeping it simple—choosing the right viscosity grade is the safest approach—don’t be misled by sales pitches and waste money.

I've been using the CS35 for several years and found that high-quality engine oil makes driving more enjoyable. 5W-40 full synthetic is my top choice—it enables faster cold starts and quicker throttle response. During aggressive driving or long highway runs, it reduces engine friction noise and maintains stable fuel consumption. Avoid mineral oils as they degrade easily and provide insufficient protection. Regular oil changes every 7,500 kilometers will keep the power output from declining.
