Which engine oil is suitable for Changan CS55?

[Braxton]

Changan CS55 uses 5w-40 synthetic engine oil. The functions of engine oil are: 1. Lubrication to reduce wear; 2. Cooling and temperature reduction; 3. Cleaning; 4. Shock absorption and buffering. Changan CS55 is a compact SUV with body dimensions of: length 4500mm, width 1855mm, height 1690mm, wheelbase 2650mm, and fuel tank capacity of 58 liters. Changan CS55 is equipped with a 1.5T turbocharged engine, with a maximum power of 115kW at 5500rpm, maximum torque of 225Nm, and matched with a 6-speed manual transmission.

Based on my experience driving the Changan CS55, the manual recommends using 5W-30 synthetic oil. Brands like Shell Fully Synthetic or Mobil 1 are very suitable as they are compatible with this SUV's 1.5T engine. In northern winters during cold starts, 5W-30 flows well and lubricates quickly, while it doesn’t thin out in summer heat. Don’t skimp and use mineral oil—it leads to carbon buildup and affects performance. I change the oil every 7,000 km or so, but if there’s frequent city traffic congestion, I do it earlier at 5,000 km. Regular maintenance can extend the engine’s lifespan by over ten years, saving on repair costs. Choose reputable oil brands to ensure quality and compatibility, and always check the vehicle manual for details to avoid wasting money on incompatible oils.

As a technician with over 20 years of repair experience, I recommend using 5W-30 full synthetic oil for the Changan CS55. The API specification should be SN or SP grade to ensure cleanliness and anti-wear performance. The engine design suits this viscosity, providing component protection at high temperatures and smooth cold starts. Check the oil regularly and replace it if the level is too low or the oil appears too dark. Choose reliable brands like Castrol or Total for oil, and don't overlook the quality of the oil filter. A reasonable oil change interval is every 5,000 to 7,500 kilometers, depending on driving habits. Develop the habit of regularly checking the oil level by simply wiping the dipstick with a tissue to observe the color, maintaining efficient vehicle operation and reducing issues.

Considering environmental and climate factors, the Changan CS55 is more suitable for low-viscosity engine oil such as 5W-20 full synthetic, which saves fuel and reduces emissions. My research shows this oil performs better in hybrid mode, reducing carbon footprint. It still protects the engine in hot weather, preventing overheating and wear. Recommended brands include environmentally certified Longpan or Shell's low-carbon series, known for stable and durable performance. For daily driving, pay attention to the sustainability of the oil and combine it with green maintenance habits to extend the vehicle's lifespan. Before changing the oil, simply check the manual's recommendations to ensure compatibility, safety, reliability, and efficient handling of environmental responsibilities.
