What type of engine oil is used for the Changan CS85 COUPE?
4 Answers
Changan CS85 COUPE uses 5W30 engine oil. Engine oil serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. For regular maintenance, semi-synthetic oil should be changed every 5,000 kilometers, while full-synthetic oil requires replacement every 10,000 kilometers. To extend the engine's lifespan, it is advisable to change the oil 500 kilometers earlier. The Changan CS85 COUPE was launched in Sanya and is the first coupe SUV in the Changan SUV family. Positioned as a mid-size coupe SUV, it is equipped with a 2.0T engine and offers four models based on configuration: Type, Dynamic, Premium, and Intelligent.
I've been driving the Changan CS85 COUPE for several years and recommend using 5W-30 full synthetic oil, which is the official Changan-recommended specification. It provides good lubrication during cold winter starts without engine hesitation, and maintains stable oil film protection for the engine under high summer temperatures. My driving style is relatively aggressive with lots of highway miles, so this viscosity helps reduce friction, making the car more fuel-efficient and durable. Don't forget regular oil changes - every 5,000 kilometers or six months - and check the oil level to avoid engine wear and major issues. For brands, I've had good experience with Shell and Mobil, both offering great value. If unsure, directly consult the owner's manual or visit a 4S dealership to prevent choosing the wrong oil and damaging the engine. Proper maintenance ensures smoother driving overall.
As a commuter using the CS85 COUPE, saving money is my top priority. Using 5W-30 semi-synthetic oil is sufficient—Changan's engine has good compatibility, and this type of oil is much cheaper than full synthetic, saving me dozens of dollars on gas each month. I never change oil at dealerships due to high costs; instead, I buy reputable brands like Castrol online and have it changed at a reliable repair shop for just 100-200 RMB per service. For daily city driving, there are no major issues, and temperature differences between winter and summer have minimal impact. Just be sure to avoid off-brand oils, as they can cause sluggish acceleration and higher fuel consumption, ultimately wasting money. I recommend changing the oil every 7,000 km—regular maintenance keeps the car trouble-free, saving money and providing peace of mind. Don’t compromise engine health for short-term savings.
After playing with cars for a long time, I know that the CS85 COUPE uses a Blue Whale engine, which is suitable for low-viscosity oils like 5W-30 or 0W-40, mainly to reduce running resistance and improve efficiency. Viscosity parameters are key—good fluidity in cold weather prevents freezing, while maintaining pressure in summer. Choose high-grade certified oils like API SN or ACEA A5/B5 to prevent carbon buildup and oxidation. Driving style matters a lot; since I often drive on highways, I use full synthetic oil to ensure oil film stability. Regularly check the oil color—if it turns black, it’s time to change it, don’t push it to 8,000 km. Remember the specifications in the manual; using the wrong viscosity may cause loud noises or even damage the cylinder block.
