"Three -point oil under the driver's feet" If analyzed from a narrow level，refers to: Whether the owner takes the acceleration of the accelerator or the brakes to slow down during the driving process。Stepping the brakes need to involve the braking system，Once the braking system starts to run，The fuel consumption will rise。So，Many old drivers say，Seabet

Step on the accelerator to speed up, let alone，We all know，The larger the vehicle displacement, the greater the fuel consumption, the higher the fuel consumption，Of course this is the theoretical situation，Not all cars are suitable for this，However, under normal circumstances，Principles are such principles。So，Once stepped on the accelerator，The amount of oil will also increase。

Therefore, some old drivers often say，If you want to save fuel，It is best to start with the two aspects of the brakes and the accelerator，Keep the car driving at a constant speed，Don't be greedy，Don't pursue passion at speed，but from the perspective of fuel -saving。

Also，If the car is driving at a constant speed，To a certain extent, it will reduce the number of brakes，Because the Seabetspeed is not so fast，You can slow down slowly in advance when encountering traffic lights，If it is a high -speed driving，So I can only step on the brakes。

"Three -point oil under the driver's feet" analyzes from a broad level，mainly refers toThe driving habits of the owner will increase the fuel consumption。Many people are buying a car，Will choose a model with low fuel consumption of the Ministry of Industry and Information Technology，Want to save fuel。However, I found it after I really drove，The actual fuel consumption is much higher than the Ministry of Industry and Information Technology announced。

Is this the question really lying? not necessarily，The manufacturer may be tested in the most ideal state when measured，But in real life，The driving technology of the owners、Car habits are different。

The same car，Some car owners can run 100 kilometers more than some car owners who do not understand fuel saving skills，This is different from person to person。If the owner does not understand "three points under the driver's feetOil "narrow and broad sense，I don’t know how to save fuel，So the same box of oil can run less 100 kilometers。
