What kind of engine oil should be added to Geely Vision?

Geely Vision should use 20W50 or 15W40 API SJ/SL multigrade engine oil in summer, and 10W30 or 5W30 API SJ/SL engine oil in winter. The following are precautions for refueling: Avoid filling the tank completely: When driving in the city, there's no need to fill the fuel tank completely. Frequent stops in urban driving can increase engine load if the tank is full. It's best not to exceed 2/3 of the tank capacity. Overfilling may cause fuel overflow, which can flow into the intake manifold through pipelines and "flood" the spark plugs, leading to engine stalling after refueling. In severe cases, this may prevent normal engine starting, or even cause fuel leakage from the carbon canister, creating significant fire hazards when exposed to open flames. Don't wait until the tank is empty to refuel: The fuel pump in the tank relies on gasoline for cooling. If the fuel level is too low to submerge the pump, prolonged operation in this condition will shorten the pump's lifespan. While this is less critical in winter, the risk is higher during hot summer months. Additionally, when fuel is extremely low, the pump may draw sediment from the tank bottom, potentially clogging the fuel pump or blocking fuel lines.
I drove the Geely Vision for a while and found that 5W-30 oil works best. This oil has moderate viscosity, ensuring smooth cold starts in winter without being too thin in summer, providing excellent engine lubrication protection. I prefer using full synthetic oil—though more expensive, it reduces engine noise and lasts longer. The optimal oil change interval is every 5,000 to 7,000 km, or check the oil level every six months. If it turns black or shows sediment, replace it immediately. Don’t forget to change the oil filter simultaneously to avoid clogging issues. During daily driving, aggressive acceleration speeds up oil degradation, while smooth driving saves fuel. I buy reputable brands like Shell or Great Wall online for affordability and doorstep delivery, saving money and hassle.
