What is the function of gasoline additives?

Fuel additives are useful. The chemical composition of fuel additives contains cleaning agents that can effectively clean or inhibit carbon deposits in the engine, addressing issues such as insufficient power and fault codes caused by fuel quality. The specific functions of fuel additives include: removing carbon deposits and cleaning the fuel system; enhancing power; saving fuel; preventing corrosion, rust, lubrication, and noise reduction; cleaning carbon deposits and gum deposits in the engine intake and fuel injectors; and using corrosion inhibitors, anti-knock agents, and combustion improvers to prevent corrosion, resist knocking, and improve combustion efficiency. In the era of multi-point fuel injection, the main component of fuel additives was mostly PIBA (polyisobutylene amine), a polymer with a polyether main chain and an amine end group, which could remove some gum deposits. However, in the era of direct injection, due to the high-temperature and high-pressure environment (combustion chamber) of direct injection vehicles, volatility is poor, leading to rapid formation of deposits. Therefore, adding traditional fuel additives to direct injection vehicles not only fails to clean combustion chamber carbon deposits but also significantly increases carbon buildup. Nowadays, most fuel additives contain PEA (polyether amine), which can continue to clean under high-temperature conditions, making it suitable for direct injection engines and more effective in removing carbon deposits. Additionally, most current fuel additives include gasoline cleaning components that effectively clean gasoline, prevent oxidation, and improve energy efficiency. The national standard for fuel additives is GB19592-2004. Only those that meet this standard are considered legitimate fuel additives, so consumers should pay attention when purchasing.
Gasoline additives are quite effective, and as a long-time user, I add some with every fill-up. They clean deposits from the fuel injectors and intake pipes, prevent carbon buildup, and make the engine run smoother. After years of driving, I’ve noticed quicker acceleration response and an average fuel consumption reduction of about 5%. They also offer protection by lubricating critical components to avoid wear. In cold seasons, additives can prevent freezing and protect the fuel system. I recommend regular use—don’t wait until engine problems arise to regret it. It saves money and hassle while extending engine life. By the way, choosing reputable brands is crucial; don’t just go for the cheapest option. In short, using them makes the car run much smoother and maintenance easier.
