How many kilometers should a new car run before using fuel additives
2 Answers
New cars should use fuel additives after running 10,000 kilometers. The functions of fuel additives include improving combustion efficiency, maintaining normal engine power output, and keeping the engine clean. The amount of fuel additive to be added at one time depends on the remaining fuel in the tank, so refer to the fuel additive instructions. Functions of fuel additives: Fuel additives help improve fuel combustion efficiency, reduce fuel waste, save fuel, maintain sufficient engine power, reduce incorrect engine output, minimize engine oil contamination, and keep the engine clean. How much fuel additive should be added at one time: When the fuel in the tank decreases, the power output will weaken. Adding fuel additives at this time can ensure complete fuel combustion and meet power output requirements. Fuel additives are suitable for various new cars, but the specific proportion should be determined according to the fuel additive instructions to avoid misuse.
Regarding when to add fuel additives for a new car, I believe it's better to start using them after the car has run over 5,000 kilometers. Especially nowadays, with varying fuel quality in cities, additives can prevent carbon buildup in the fuel injectors and avoid long-term impacts on engine performance. When I first bought my car, I didn’t rush to add them. After the break-in period of 5,000 kilometers, I started adding cleaning-type additives regularly, such as reputable brands like Chevron, which provide stable results. The throttle response became more sensitive, and fuel consumption slightly decreased. Although new engines have a protective layer initially, adding additives early can extend their lifespan. I recommend adding them every 5,000 kilometers or every six months, combined with highway driving to flush out carbon deposits more effectively. In short, don’t add them too early to avoid wasting money or interfering with the break-in process—just pay more attention to fuel quality.
