What Are the Functions of Automotive Fuel Additives?
2 Answers
Automotive fuel additives serve the following purposes: 1. Remove carbon deposits and clean the fuel system; 2. Enhance engine performance; 3. Improve atomization and increase thermal efficiency; 4. Provide anti-corrosion, anti-rust, and lubrication protection for the engine; 5. Reduce noise and wear, extending engine lifespan; 6. Eliminate black smoke and lower emissions. The method for adding fuel additives is as follows: 1. Before adding the fuel additive, check the fuel level in the tank—only add the additive when refueling is needed; 2. Park the car near the fuel pump and open the fuel cap; 3. Open the fuel additive bottle cap and pour it into the fuel tank; 4. Fill the tank with gasoline to help disperse and mix the additive with the fuel.
After driving for so many years, I find fuel additives really useful. The core benefit is cleaning carbon deposits in the engine, especially those accumulated on fuel injectors and cylinder walls, which improves fuel atomization and ensures more complete combustion. The power response noticeably improves—the car feels more responsive when stepping on the gas, and acceleration becomes smoother. Fuel consumption can drop slightly; I personally tested and found that a full tank could last dozens of kilometers longer, saving money in the long run. It also helps reduce exhaust emissions, contributing a bit to the environment. However, it's important to add them regularly as per the manual—usually one bottle every 5,000 kilometers—and avoid cheap products to prevent side effects. Overall, they help extend engine life and prevent premature major repairs.
