Do new cars need fuel additives?
2 Answers
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.
