Is it necessary to add fuel additive for a new car?
3 Answers
Whether to add fuel additive for a new car is optional, as it has little impact on the vehicle. The gasoline produced in China today already contains fuel detergent before it is delivered to gas stations, so adding fuel additive is not a must. The benefits of using fuel additive for the engine include: 1. Cleaning the fuel system; 2. Improving atomization. Fuel additive is the third-generation gasoline detergent, also known as gasoline detergent or fuel additive, designed to solve the carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restore engine performance, compensate for gasoline deficiencies, and impart new beneficial characteristics to gasoline, such as improving atomization, reducing wear, protecting the engine, and lowering emissions.
To be honest, I don't think new cars really need fuel additives right away. The engine in a new car is quite clean, and it's been properly set up at the factory—just like the SUV I recently bought, where the manual explicitly advises against unnecessary tinkering for the first 10,000 to 20,000 kilometers. Fuel additives are mainly for cleaning carbon deposits, but new cars hardly have any buildup. Adding them carelessly might clog the fuel injectors or disrupt the fuel system, and if something goes wrong, it might not even be covered under warranty—what a waste! I only consider using them occasionally when there's less highway driving and more city stop-and-go traffic, like after prolonged urban commuting. Generally, adding them every few tens of thousands of kilometers is sufficient. For new cars, it's just a waste of money and could even cause trouble—better to save it for other maintenance needs. Remember, driving smoothly is far more effective than relying on additives—the engine's quality is already solid.
From a scientific perspective, I recommend new car owners not rush to buy fuel additives. New car engines have excellent sealing, and the fuel is almost completely burned. The chemical components in additives, such as detergents, may help break down some carbon deposits, but they offer little benefit to new components and could even corrode internal parts. I've considered that engines are designed for high efficiency, and modern fuels already contain plenty of optimizers—adding more might do more harm than good. If you frequently drive in congested areas where the engine is prone to soot buildup, wait until you've driven tens of thousands of kilometers before considering it. I've tried running smoothly without additives, and for a new car, it's more cost-effective to spend money on oil changes. Saving those few bucks on fuel additives for a cup of coffee sounds much more pleasant.
