Is it necessary to add gasoline additive?
2 Answers
Whether it is necessary to add gasoline additive depends on the condition of the vehicle. Generally, new cars do not need it, but if the car has been used for a long time, adding it can improve engine performance. It can also be added when the fuel quality is not good, as it can enhance the car's power. Gasoline additive can improve combustion efficiency, reduce fuel consumption, and help decompose and remove deposits in the combustion chamber, preventing future buildup. A clean combustion chamber allows the engine to operate more smoothly, significantly reducing nitrogen oxide emissions and enabling the use of lower-octane fuel. Gasoline additive also has anti-rust and rust-removing effects. After adding it, it effectively cleans the fuel system and forms a protective film on the fuel system and engine cylinder surfaces, providing protection against corrosion and damage caused by low-quality gasoline. This improves engine starting performance, enhances power, and extends the engine's lifespan.
Having worked in the automotive repair field for many years, I've seen a lot of discussions about fuel additives. Their main function is to clean the fuel system and remove carbon deposits, especially suitable for older cars or those frequently driven in congested urban areas where rust and carbon buildup are common. Using them can improve power and fuel efficiency. However, they're not a must-have; new car engines are well-designed and don't necessarily need them. Additives come in types like cleaners and octane boosters, and it's safer to choose products from reputable brands like Shell or Total. I recommend using them only when symptoms like unstable idling appear; normally, using high-quality gasoline is sufficient. Over-reliance can waste money and may even corrode components, so regular engine maintenance is a better way to prevent issues. In short, necessity depends on the vehicle's condition and personal habits—don't just follow the trend to use them.
