What type of engine oil is suitable for the Dongfeng Fengshen AX7?
2 Answers
The Dongfeng Fengshen AX7 should use 5W-30 full synthetic engine oil. Below is relevant information about the Dongfeng Fengshen AX7: 1. Powertrain: This model offers three powertrain variants, equipped with 1.4T, 1.5T, and 1.6T turbocharged engines respectively. Since the vehicle uses a turbocharged engine, it can utilize either semi-synthetic or full synthetic engine oil. 2. There are three types of engine oils used in automobiles: mineral oil, semi-synthetic oil, and full synthetic oil. The classification exists primarily because these three types serve different functions. Full synthetic oil provides superior performance compared to mineral and semi-synthetic oils, offering better protection for the engine during operation. 3. Compared to naturally aspirated engines, turbocharged engines like those in this vehicle generate greater power output during operation. Due to their different internal structures, turbocharged engines experience more significant wear on internal components. During operation, engine oil forms a protective oil film inside the engine, which enhances component protection.
I understand that the choice of engine oil for Dongfeng Fengshen AX7 mainly depends on the vehicle's age and engine type. For new cars, fully synthetic oil is more reliable, with a viscosity grade like 5W-30 being a good fit for daily city driving, ensuring smoother engine operation and better fuel efficiency. For older AX7 models with turbocharged engines, it's best to use 5W-40 oil to handle high temperatures. Don’t forget to refer to the owner’s manual for specific recommendations, as most require API SN or SP grade; otherwise, the oil pump or valves may wear out faster. I recommend checking the oil level every 5,000 kilometers and using specialized antifreeze oil in cold regions to avoid winter starting difficulties. Brands like Shell or Mobil offer good value for money—avoid cheap, low-quality products to ensure driving safety.
