What type of engine oil is used for the Changan CS95?
3 Answers
The Changan CS95 uses 5W40 engine oil, but it should be flexibly analyzed based on actual conditions. For example, in extremely cold regions such as Northeast China, 0W40 engine oil should be used. The body dimensions of the Changan CS95 are 4949 mm in length, 1930 mm in width, and 1790 mm in height, with a wheelbase of 2810 mm. The Changan CS95 features front-wheel drive, with a front suspension type of MacPherson independent suspension and a rear suspension type of multi-link independent suspension. The body structure is a unibody design. The Changan CS95 is equipped with a 2.0T turbocharged engine, paired with a 6-speed automatic transmission.
I've been driving my Changan CS95 for over a year now, always using 5W-30 full synthetic oil, and it's been performing very steadily. The car has a 2.0T engine, and I mainly drive it in Beijing. It starts up quickly even in cold winters without any stuttering, and I haven't noticed any engine overheating during hot summers. Choosing the right oil viscosity is crucial—too thick and it slows down startup, too thin and it offers poor protection in summer. 5W-30 is a versatile choice. I change the oil every 8,000 kilometers or every six months during professional maintenance at the shop, which costs a few hundred yuan. I also make sure to use synthetic oil with an API SN rating or higher to prevent carbon buildup and extend engine life. Extra tip: If you frequently take long trips, you can add an oil additive to improve lubrication, but don't rely too much on it—the base oil is what really matters. Overall, engine oil is the heart of your engine, so don't cut corners here. Saving a little now could lead to much higher repair costs later.
As an experienced professional who frequently deals with cars, I believe the engine oil for the Changan CS95 should be selected based on viscosity. 5W-30 synthetic oil is the mainstream recommendation, especially for better protection of turbocharged engines. Lower viscosity oils like 0W-20 provide smoother starts in winter but are unsuitable for high-temperature seasons. Conversely, higher viscosity oils like 10W-40 may be too thick, affecting fuel efficiency. In terms of API certification, at least SN-grade oil is necessary to ensure cleanliness and prevent piston damage from deposits. Having tried several branded oils, I find synthetic oils more durable, with a reasonable oil change interval of around 7,500 kilometers. Variable weather can impact oil performance, so it's advisable for those in northern regions to check oil quality before winter. Regularly inspecting the dipstick is a good practice—if the oil darkens or shows impurities, an early change is recommended. The key is to use genuine oil; avoid cheap counterfeit products to prevent accelerated engine wear. When changing oil, ask the technician to check other components for a hassle-free experience.
