Why Do Cars Need Fuel Additives?
2 Answers
The reasons for using fuel additives in cars: To protect the delicate direct injection equipment, the holes in the fuel injectors are very fine, and the carbon deposits generated from combustion can easily clog the injectors. The active ingredients in gasoline additives can clean the injectors during fuel injection, keeping the fuel injection system efficient and unobstructed. When the engine is running, the temperature of the fuel injectors is around 100 degrees Celsius, while the intake valve temperature is even higher, generally between 200 to 300 degrees Celsius. At such high temperatures, unstable components in the fuel are prone to oxidation and combination reactions, forming carbon deposits and gum deposits that settle on the intake valves and fuel injectors.
As a veteran driver with nearly 20 years of experience, I find fuel additives quite effective. Their main benefit is cleaning engine carbon deposits and preventing fuel injector clogging. If you often drive short distances in the city where engines accumulate deposits quickly, using additives leads to more complete combustion, making the car run smoother with reduced vibration and noise. In the long run, it saves you from costly major repairs. Adding one bottle monthly costs less than a few dozen yuan, yet significantly extends engine life—especially noticeable for vehicles with over 100,000 kilometers. Remember to combine this with regular maintenance to develop good habits that are both safe and economical.
