How Much Higher Is the Fuel Consumption of a New Car Compared to Normal?
2 Answers
The amount by which a new car's fuel consumption is higher than normal varies depending on the car model and driving habits. Here is some relevant information about new car fuel consumption: 1. Reasons for high fuel consumption in new cars: Insufficient break-in period; clogged fuel lines; damaged oxygen sensor; prolonged use without replacing the "three filters" (air, oil, and fuel filters). 2. Is high fuel consumption in new cars normal? High fuel consumption in new cars is a normal phenomenon. New cars are in the break-in period when first purchased, during which the engine's internal operating resistance is relatively high, leading to slightly higher fuel consumption. During the break-in period, it is advisable to avoid aggressive driving. After the first maintenance, the car's fuel consumption will return to normal levels.
I've been driving for almost ten years and have purchased several new cars. When the car is brand new, the fuel consumption is indeed higher than normal, usually about 15% to 20% higher. In the first two months, a full tank of gas seems to run out particularly fast, burning about 1-2 liters more per 100 kilometers. The main reason is that the new parts are too tight—the engine piston rings and cylinder walls haven't been properly broken in yet, and the transmission gears are also tightly meshed, resulting in higher friction resistance. I remember when my SUV was new, the fuel consumption was over 11 liters per 100 km, but after a few highway trips, it dropped to around 9.3 by the first service. It's best not to floor the accelerator during the first 2,000 kilometers of a new car; wait for the RPM to naturally decrease, and it will drive smoother.
