Is Adding Fuel Additive Useful for Cars?
2 Answers
Adding fuel additive is useful for cars. Adding a cleaning-type fuel additive can effectively remove carbon deposits inside the engine by attaching to the pores of the carbon deposits and then decomposing and eliminating them. This is especially true for turbocharged engines, which can accumulate a lot of carbon deposits over long-term use. In such cases, adding this type of cleaning fuel additive is necessary. However, it is not recommended to use fuel additives for extended periods (once every 5,000 kilometers is sufficient), as it can easily clog the three-way catalytic converter. For new cars, the fuel from gas stations already contains cleaning additives, and new cars do not produce excessive carbon deposits, so there is no need to add too much fuel additive.
As for fuel additives, I think it depends on the specific situation. Based on my driving experience over the years, for older vehicles with high mileage, like those that have run over 100,000 kilometers, carbon deposits tend to build up in the engine. Adding a bottle of fuel additive can help clean it out. After adding it, the car feels more powerful, and fuel efficiency improves as well. However, it's completely unnecessary for new cars. Modern engines are advanced and less prone to carbon buildup. Using fuel additives too frequently might even damage the fuel injectors or fuel system. Additionally, choosing the right brand is crucial, as low-quality fuel additives may have little effect or even be harmful. I sometimes try it when I notice my car struggling to accelerate on the highway, but for regular maintenance, I stick to normal practices and don’t rely on it too much.
