How long does it take for a new car's fuel consumption to decrease?

New cars typically reach their normal fuel consumption levels after driving approximately 3,000 kilometers. Generally, fuel consumption begins to decrease after the initial 1,000-kilometer break-in period. Here are the relevant details: Reasons: The components of a new car fit together more tightly, preventing the engine from fully utilizing its power, which ultimately results in higher fuel consumption. If the car is frequently driven at low speeds in urban areas, it will inevitably exhibit higher fuel consumption. Other factors influencing fuel consumption include driving conditions, driving habits, vehicle maintenance, and load capacity. Additional information: After a cold start, it's advisable to let the engine warm up until the water temperature changes before driving. Additionally, it's best to limit the load to no more than 70% of the vehicle's specified capacity.

I remember when my new car first arrived, the fuel consumption was always on the higher side. In the first few days of city driving, my car's fuel consumption could reach 10L/100km, which was indeed quite costly. It wasn't until around 500 kilometers that it started to drop, and by 1000 kilometers, it stabilized at around 7.5L. New cars all need a break-in period, where the new parts inside the engine adapt to each other, much like friends needing time to get used to each other when they first meet. While driving, I tried to maintain a steady speed, avoiding sudden acceleration and hard braking, which helps the engine adapt faster and reduces unnecessary wear. After this phase, not only did the fuel consumption drop by about 15%, but the car also ran smoother, with much steadier starts. Regular maintenance shouldn't be overlooked—changing the oil on time and other upkeep can help keep fuel consumption at its best.

I always try to save some money on fuel when driving. Don't worry about the high fuel consumption during the break-in period of a new car; it usually drops significantly after driving about 1,500 kilometers. My experience is to pay attention to driving habits from the moment you get the new car, such as driving slowly in the city, not speeding too much on the highway, and starting smoothly with fewer sudden stops. The fuel consumption in the first 500 kilometers might be around 11L, but it gradually dropped to about 8L in just a few months. After the engine is properly broken in, its coordination improves, and reduced resistance naturally leads to fuel savings. I also noticed by recording the fuel gauge that highway driving helps the break-in process faster than congested roads. It's advisable not to overload the car within the first thousand kilometers and to control the gear-shifting timing to accelerate the break-in, which not only stabilizes fuel consumption but also extends the car's lifespan.

I just bought a new car, and the fuel consumption was quite high at first. A friend told me there's a break-in period. Simply put, the new engine needs time to adapt, and after driving a few hundred kilometers, it will normalize. My car's fuel consumption dropped from 10L to 7.5L over about 600 kilometers. Just drive gently and avoid stomping on the accelerator too often.
