What type of engine oil should be used for the Changan CS75?
3 Answers
Changan CS75 uses 5W30 engine oil. Engine oil serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Taking the 2021 Changan CS75 as an example, it is a compact SUV with body dimensions of length 4650mm, width 1850mm, height 1715mm, a wheelbase of 2700mm, a fuel tank capacity of 58 liters, and a trunk capacity of 520 liters. The 2021 Changan CS75 is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 178PS, a maximum power of 131kW, a maximum torque of 265Nm, and is paired with a 6-speed manual transmission.
I've been driving my Changan CS75 for several years, always using 5W-30 full synthetic oil as per the owner's manual. This viscosity grade ensures quick lubrication during cold starts and smooth operation in hot weather; avoiding incorrect grades like 10W-40 that could increase fuel consumption or accelerate wear. I adhere to oil changes every 5,000 kilometers. Checking oil level is simple: pull out the dipstick, wipe it clean, reinsert it, then check the oil level line. Proper engine oil protects the engine, extends its lifespan, and improves fuel efficiency, saving money and hassle. Neglecting this may cause insufficient oil pressure or overheating issues, increasing maintenance costs. It's recommended to choose brands with API SN certification to ensure reliability.
Throughout my career in auto repair, I've encountered cases where the Changan CS75 experienced malfunctions due to oil-related issues. I recommend using 5W-30 synthetic oil - the SAE 5W ensures smooth flow in cold weather, while the 30 maintains protective layers at high temperatures. The engine design is optimized for this viscosity grade. Incorrect choices like overly thin oil reduce lubrication, while excessively thick oil increases resistance. I advise owners to follow an oil change interval of 5,000 to 7,500 kilometers, while simultaneously checking the oil filter to maintain cleanliness. Using the correct oil grade prevents bearing failures or carbon buildup issues, helping avoid costly overhauls.
