Which engine oil is suitable for Changan CS55?
2 Answers
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.
