Is it necessary to add fuel additive for a new car?

[VanHayden]

Since the effect of fuel additives is relatively limited, and the fuel at domestic gas stations basically already contains fuel additive components, coupled with the fact that new car engines have short service life and good working conditions, carbon deposits are unlikely to form. Therefore, there is absolutely no need to add fuel additives to a new car. More details are as follows: 1. Fuel additives, also known as fuel system cleaners, primarily function to remove carbon deposits, which has always been their main selling point. Additionally, they assist in maintaining the engine and fuel system. Some specialized fuel additives can also improve the fuel's anti-knock properties (octane rating). 2. Fuel additives are mainly composed of nano-molecules, cleaning active factors, antioxidants, anti-corrosion agents, demulsifiers, and more than ten other components. They are designed to target harmful substances in fuel such as sulfur, gum, and engine carbon deposits, thereby enhancing power, promoting combustion, providing anti-oxidation, anti-wear, cleaning, dispersing, demulsifying, anti-corrosion, and lubricating effects.

When I first bought my new car, I also struggled with whether to add fuel system cleaner. I asked some friends at repair shops, and they all said that the new car's engine was already cleaned and adjusted before leaving the factory, with very little carbon buildup, so there was no need for additional cleaners. I drove for over a year without adding anything, and the car still runs smoothly with decent fuel consumption. I recommend saving this expense for the first 20,000 kilometers of a new car and focusing on regular maintenance, such as timely oil changes and air filter checks. If you frequently drive in congested urban areas, occasionally adding some as a preventive measure is fine, but don’t expect any significant improvements. Remember, new cars are designed for long-term durability, so don’t stress too much about additives. Spending more time understanding the maintenance recommendations in the owner’s manual is far more practical.

As an experienced driver who has owned several cars, I don't think fuel additives are necessary for new vehicles. When a new engine is just breaking in, the internal components have high surface finish, making the effects of fuel additives almost unnoticeable. It's a waste of money and effort. Instead, it's better to develop good driving habits, such as avoiding rapid acceleration at high speeds and maintaining steady driving. If cleaning is really needed, wait until the car has run 10,000 to 20,000 kilometers, then decide whether to use additives based on actual performance. The key is to pay more attention to fuel quality, such as using fuel from reputable gas stations, which is much more reliable than additives. Long-term maintenance is crucial—don't be fooled by advertisements and waste your money.

From an automotive technology perspective, new car engines have minimal carbon buildup issues. Fuel additives are cleaning products designed for older vehicles, and adding them to new cars won't significantly improve performance. Modern vehicles feature advanced control systems that can self-adjust combustion to maintain efficiency. I recommend new car owners skip it unless specifically recommended in the manual. Pay attention to driving environments - only consider using it semi-annually if frequently driving in dusty areas. Other investments, such as new tires, offer better value for money.
