Should You Add Fuel Additives to Your Car?

[MacDeclan]

Adding fuel additives to your car is beneficial, as they not only help remove carbon deposits but also inhibit their formation. Cleaning-type fuel additives can adhere to metal surfaces, forming a protective film that reduces carbon buildup. When refueling, first add a bottle of fuel additive, then fill up the tank. Using it once every four fuel tank refills can achieve efficient cleaning and gentle maintenance. With long-term use, an endoscope will reveal that the thick carbon deposits on the piston tops inside the cylinders gradually clear, exposing shiny metal surfaces. High-quality fuel additives positively impact carbon deposits, fuel consumption, emissions, and performance (such as power and acceleration), while low-quality ones can be harmful. Therefore, it's crucial to choose fuel additives carefully—avoid low-quality products, as they may have adverse effects. There are two types of automotive fuel additives: octane boosters and fuel system cleaners. The former is rarely used in mainland regions, while the latter is recommended for regular use.
