What oil should be used for the first maintenance of Changan CS75?

When performing maintenance on the Changan CS75, replace it with Changan's original SL-grade 5W-30 engine oil. Below is a detailed introduction to the maintenance content for the Changan CS75: 1. Replace the fuel filter and air filter. Check the clutch stroke, the clearance and fixation of the steering lower arm ball joint, and the dust cover. 2. Check the tread depth, tire pressure, and wear condition of the tires, and perform a four-wheel alignment if necessary. Check whether the throttle and idle valve are too dirty, and clean them if necessary. 3. Check the condition of the spark plugs and replace them if necessary. Perform a no-disassembly cleaning of the fuel injectors. Check the condition of the power steering, braking system, and automatic transmission. 4. Test whether the braking force, gear shifting, and steering are normal. Lubricate all relevant parts of the vehicle.
Last year, I bought a Changan CS75 and specifically researched engine oil options during the first maintenance. The 4S dealership recommended using 5W-30 full synthetic oil because the new engine requires good lubrication and protection. I used Shell or Mobil brands, which have moderate viscosity, adapt to different temperatures, and reduce wear. After the oil change, the engine felt smoother, and fuel consumption slightly decreased. Actually, the first maintenance is usually around 5,000 kilometers—don’t delay it too long, as it may affect the warranty. Oil quality is crucial; full synthetic is more expensive than semi-synthetic but offers better long-term cleaning performance and extends engine life. I also asked the technicians, and they said the CS75’s engine design is matched with this type of oil to avoid issues caused by incorrect viscosity. Usually, pay attention to road conditions while driving and check the oil level regularly to ensure safe driving.
As a frequent car repairer, I recommend using 5W-30 full synthetic oil for the first maintenance of the Changan CS75. This viscosity standard is suitable for most climates, protecting engine components and preventing oxidation and carbon buildup at high temperatures. Synthetic oil has a more stable molecular structure, reducing friction and improving fuel efficiency. When changing the oil, check the oil filter to ensure the entire system is clean. The first maintenance is best done within 5,000 kilometers. Avoid using inferior oil, as it can cause increased engine noise or higher fuel consumption. If the budget is limited, semi-synthetic oil is also an option, but full synthetic is more durable. Remember to check the vehicle manual to confirm specifications and avoid using high-viscosity oil by mistake. After maintenance, test drive the car; if it feels smooth, then it's done right.
I just picked up my Changan CS75 and was a bit confused during the first maintenance, but the manual recommends using 5W-30 oil. The 5W represents low-temperature fluidity, and 30 is for high-temperature protection. I opted for full synthetic oil and had it changed at the 4S dealership—the process was straightforward. Oil quality affects engine health, and regular changes can prevent premature wear. After the first maintenance, driving feels more reassuring. I recommend that all new car owners learn about maintenance in advance. Don’t overlook this, or repair costs could be high.
