Fuel additive can be added after refueling. Below are the introduction and precautions regarding fuel additives: Introduction to Fuel Additives: Fuel additive, commonly known as the third-generation gasoline detergent, is designed to address carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restore the engine to optimal performance, and compensate for certain deficiencies in gasoline while imparting new beneficial properties. Fuel additives are high-threshold technical products with high costs and unit prices, making them a hotspot for numerous low-quality and even counterfeit products. Using counterfeit products not only fails to remove carbon deposits and protect the engine but may also cause damage to the engine. Therefore, it is essential to purchase from legitimate channels such as physical specialty stores, official online flagship stores, and authorized 4S shops. Precautions for Adding Fuel Additives: When adding fuel additive to your car, it must be done before refueling at the gas station. Pour the fuel additive first, then add gasoline to ensure thorough dilution and mixing of the gasoline and fuel additive. If overly concentrated fuel additive directly enters the cylinder without burning, it may cause the engine to stall or result in incomplete combustion. If the fuel gauge indicates low fuel and you add fuel additive without promptly refueling, it may lead to insufficient power and stalling. Refilling the tank and starting the engine several times should resolve the issue.
