Do new cars need fuel additives?

[ArabellaMarie]

New cars do not need fuel additives. Fuel additives are substances added directly to the vehicle's fuel tank to clean carbon deposits, maintain the engine, improve atomization, reduce wear, and lower emissions. The method for adding fuel additives is as follows: add the fuel additive to an almost empty fuel tank, then fill up with gasoline. Precautions for using fuel additives include: 1. Add the fuel additive before refueling to ensure thorough dilution and mixing with gasoline; 2. After using fuel additives, vehicle emissions may fail inspection tests; 3. Older engines should not be driven long distances or at high speeds immediately after using fuel additives; 4. Do not use excessive amounts; 5. Add one bottle of fuel additive when the tank is two-thirds or half full; 6. A cycle consists of adding fuel additives six times, with 12 times being an optimal usage cycle.

I just bought a brand-new car and specifically consulted several experienced auto mechanics about using fuel additives. They unanimously agreed that since the engine internals of a new car are designed to be clean with minimal carbon buildup, there's no need to start using fuel additives right away. Manufacturers ensure that the original fuel is sufficient for daily driving during testing, and adding additives might just be a waste of money or even counterproductive. In the long run, if driving habits involve frequent short trips or heavy city traffic, leading to gradual oil residue buildup in the engine, then using high-quality fuel additives can help prevent carbon deposits. But don’t rush into it—observe for six months to a year first, and only consider trying them after the warranty period or if you notice minor unusual noises. The key is regular maintenance, like changing the engine oil and cleaning the filter every 5,000 kilometers, which is far more reliable and safer than additives. In short, saving money and peace of mind come first.

I've been driving for many years and have purchased several new cars, but I've never started using fuel additives from the beginning. New cars are tested before leaving the factory, and their fuel systems are clean and clear. Additives might actually cause blockages or make the engine prematurely dependent on them. Once, I bought a bottle at a gas station on the recommendation of a salesperson, but I didn't notice any change in power and just wasted a few dozen bucks. Unless the owner's manual specifically says it's okay to add them, or you frequently drive on poor highway conditions, there's really no need to consider them. A cost-effective approach is to regularly change the standard engine oil and maintain the vehicle properly, which is more reliable than these products. Remember, a car is a tool—don't waste money unnecessarily. Safe driving is the core. I recommend ignoring additives in the first year and focusing on simple maintenance.

There's really no need to rush into using fuel additives for a new car. Through discussions in car owner groups, I've learned that new car engines are already clean from the factory. Fuel additives mainly clean carbon deposits, but new cars have minimal carbon buildup, making the additives ineffective and a waste of money. I recommend driving for about 10,000 kilometers first to assess the car's condition. Only if you notice slower starts or increased fuel consumption should you consider trying them. Additives work by using chemicals to dissolve oil residues, but excessive use might affect sensors or exhaust emissions. If you do buy them, choose reputable brands—don't go for cheap products. Regular maintenance is more important. Keeping it simple is the way to go.

I just drove my newly bought car home when my neighbor Lao Zhao reminded me not to casually add fuel additives. He said the new car's system is designed with precision, and the original oil is sufficient; additives are unnecessary. After checking some materials, I found that adding additives immediately to a new car might cause fuel system fluctuations or ineffective consumption, which could negatively affect long-term performance. It's better to save the money for comprehensive checks, like going to the 4S shop every quarter for a scan and keeping the air filter clean and functional. If you notice any abnormal engine noises later on, you can use additives in moderation to prevent carbon buildup, but definitely skip this during the new car phase. Remember, safety comes first—don't fuss over minor things.
