    The driving habits are different, the road conditions are different, the traffic jam, the load, the oil, the hot and cold air, whether the run-in period of the old car is different, and the fuel consumption is not the same. It is recommended to calculate it yourself according to the following method:

    1.According to the trip computer on the car. Generally, better cars have a trip computer with real-time fuel consumption and average fuel consumption.

    When you want to calculate fuel consumption, empty the data inside, and the average fuel consumption read is more accurate. Some cars do not support the driving computer or the computer does not support clearing data, so the second method can only be used.

    Some people also say that the data calculated by the driving computer is inaccurate. But the amount of fuel is controlled by the car, and the car can also know the number of kilometers, so why is the data inaccurate? Therefore, the data calculated by the driving computer should still be reliable.

    2.Each of the following steps is required to be strictly implemented, otherwise the calculated fuel consumption may not be accurate. When refueling first, add until you jump the gun, don't refuel at this time, and record the kilometers at this time.

    Why is this method more accurate to calculate fuel consumption, because the size of the fuel tank of the car is fixed, and the fuel gun is also standard, so when it is added to the jump gun, basically the amount of fuel in the fuel tank is fixed, so we can use this method to ensure the accuracy of fuel consumption calculation to the greatest extent.

    Hello, gliding only depends on whether there is a gear, not on fuel consumption.

    Neutral gear because to maintain the engine engine engine must work at idle speed, so there is instantaneous fuel consumption, prohibiting instantaneous fuel consumption if displayed as l km value is unlimited, so the display fuel consumption unit is replaced with liters per hour. When the engine is started, if you press the accelerator pedal directly to the end, the engine control unit will cut off the power supply to the injectors, preventing fuel from being injected into the engine.

    This oil cut-off mode is mainly used to check the special working conditions of the engine or deal with some faults, for example, when we check the cylinder pressure, press the accelerator pedal to the end, at this time the throttle is fully open, the engine air intake is the largest, and the measured cylinder pressure is the most accurate.

    If the injector is still injecting fuel at this time, this part of the fuel will be discharged into the exhaust pipe and burned in the exhaust pipe at the next start, resulting in the temperature of the Tuanwang exhaust pipe being too high, and even damaging the three-way catalytic converter in serious cases, and also increasing fuel consumption and exhaust emissions.

    Modern EFI cars will stop injecting fuel when coasting, so the instantaneous fuel consumption is displayed as 0, neutral because the engine must be operated at idle speed, so there is instantaneous fuel consumption, prohibiting instantaneous fuel consumption, if the display is l km, the value is infinite, so the display fuel consumption unit is changed to liters per hour.

    Is it manual or automatic? Is it the case that the air conditioner is turned on?

    Hello dear dear, I am happy to serve you: the reason for the particularly high fuel consumption display of neutral coasting: in the past, cars mostly used carburetor engines, and neutral coasting was more fuel-efficient, but now most of the cars are full of EFI engines, and neutral coasting is not fuel-efficient in terms of structural principle.

    1. The simple understanding of the amount of fuel supply in the carburetor engine is controlled by the amount of air flowing through the carburetor, so the fuel consumption will definitely be higher when the speed is high, and coasting with gear will definitely cost more fuel than coasting in neutral gear. 2. The engine of EFI is different, the control unit of the engine guess will identify whether the throttle is closed through the sensor, whether the engine is destroyed in the idle state, if the engine is in the idle state but the speed is very high (with the gear coasting state), at this time, due to environmental protection reasons and fuel economy control, the control unit of the engine will control the fuel supply system to stop supplying fuel until the speed drops to more than 1,000 revolutions before resuming the fuel supply, this state is called overspeed breaking, That is to say, the oil supply system of more than 1,000 revolutions is not oiled. If you don't coast in gear but switch into neutral early, the engine control unit will supply fuel according to the normal idle state, and the fuel supply time of the coasting in neutral will be longer than that of coasting in gear, which means that it will be more fuel-intensive.
