Does a car need gasoline additive?
2 Answers
Whether a car needs 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 very good to enhance the car's power. Gasoline additive can improve combustion efficiency, reduce fuel consumption, and help decompose and remove deposits in the combustion chamber, while preventing future buildup. A clean combustion chamber allows the engine to operate more smoothly, significantly reducing nitrogen oxide emissions and enabling the use of fuel with a lower octane rating. Gasoline additive also has anti-rust and rust-removal effects. After adding the additive, it effectively cleans the fuel system and forms a protective film on the fuel system and engine cylinder surfaces, providing protection to reduce corrosion and damage caused by low-quality gasoline, improving engine starting performance, enhancing power, and extending the engine's lifespan.
The topic of gasoline additives is quite interesting. I think we should start with the technical details. Many new cars don't really need it because it's mainly used to clean carbon deposits in the engine or increase octane levels. But if you're driving an older car, the engine might have accumulated some sludge, and adding a bit of additive can make it run smoother. I've seen many car owners overlook this, resulting in engine shaking or significantly increased fuel consumption, which is not worth the loss. Generally, it's recommended to add a high-quality product every 10,000 kilometers. Don't be tempted to use cheap, unknown brands, as they might clog fuel injectors or damage sensors, causing more trouble. It's best to refer to your vehicle's manual or consult a 4S shop—they have professional tools to diagnose whether it's needed. Don't add it blindly to avoid wasting money and harming your car.
