What type of engine oil is used in the Changan CS55?
3 Answers
Changan CS55 can use 5w40 fully synthetic engine oil or 0w40 fully synthetic engine oil. Engine oil is known as the blood of the engine. Inside the engine, engine oil not only lubricates but also performs functions such as cleaning, sealing, buffering, rust prevention, and heat dissipation. The Changan CS55 is a compact SUV with body dimensions of 4500mm in length, 1855mm in width, and 1690mm in height, and a wheelbase of 2650mm. In terms of power, the Changan CS55 is equipped with a 1.5T turbocharged engine, which delivers a maximum power of 115 kW and a peak torque of 225 Nm. The transmission system is paired with either a 6-speed manual or a 6-speed automatic transmission.
I've been driving this Changan CS55 for over three years, always using 5W-30 full synthetic engine oil. The maintenance manual clearly recommends this grade, especially for the Blue Whale turbocharged engine. The 5W indicates low-temperature fluidity, ensuring smoother cold starts in winter; while the 30 refers to high-temperature viscosity, protecting the engine during aggressive summer driving. During my last service at the 4S店, I noticed they used Changan's genuine full synthetic oil with exactly the 5W-30 specification. It's recommended to change the oil every 7,500 kilometers or so, with 0W-30 being preferable in extremely cold northern regions. Never compromise by switching to mineral oil - only full synthetic can fully unleash the turbocharged engine's performance.
As someone who frequently helps friends with car repairs, I'm very familiar with the engine oil for the Changan CS55. The factory manual specifies 5W-30 full synthetic oil, which is directly related to the engine design. I've seen cases where people incorrectly used 10W-40 oil, resulting in skyrocketing fuel consumption and cylinder block damage. There are two key numbers to consider when selecting oil: the first number 5W indicates low-temperature fluidity, suitable for environments above -30°C; the latter number 30 refers to high-temperature protection. I recommend using premium brands like Castrol Edge that offer high viscosity matching, as their oil films can reduce turbo lag. An oil change interval of 7,000-8,000 kilometers is considered safe.
