What should I do if the fuel consumption of the car can't drop?

1, the hot train takes too long or the driving distance is too short in the morning.

You can drive in gear about half a minute after the vehicle starts, and then drive in 1 gear for a certain distance before driving normally. For some northern cities, when it is too cold in winter, the hot train time can be appropriately extended.

In addition, when the engine water temperature is too low, the computer will control the fuel injector to inject more fuel. Therefore, if the distance is very close and the water temperature is not easy to rise to normal in cold winter, then the car may become a typical example of high fuel consumption.

2. The tire pressure is abnormal or a large tire is replaced.

When tire inflation is insufficient, it will affect fuel consumption. When the tire pressure is too low, the contact area between the tire and the ground will increase, the driving resistance will be greater, and the vehicle will naturally use more oil.

3. Do not plan the route, drive on crowded roads and change lanes frequently.

Traffic jams will occur in many big cities, and some experienced drivers will choose the least crowded route between the starting point and the destination. In this regard, it is recommended that car owners plan their driving routes in advance, pay attention to local traffic information and road conditions, and avoid congested road sections.

4. "Clean" the car from time to time.

It is also a good fuel-saving method to clean the appearance of vehicles frequently and wax them regularly. The biggest resistance when the vehicle is driving comes from the air. If the vehicle has had an accident and the body has been deformed, it may affect the aerodynamic performance of the vehicle. Even a slight bump or depression will affect fuel consumption, and too much mud on the car body and snow on the car body in winter are also the burden of the vehicle.

5. Do not turn off the fire or strike the fire frequently when idling for a long time?

When waiting for a long time without moving the vehicle, it is suggested that you can choose to turn off the engine. It is often seen that taxi drivers choose to stall their carts when waiting in line. In fact, this is the best way to save fuel when encountering the same situation. ?

6. When driving, refuel a lot and brake frequently.

Starting, refueling and shifting gears at a normal speed can save a lot of oil over time. If it is not necessary to drive on the road, it is best not to overtake frequently. Driving at a constant speed can reduce fuel consumption. In addition, mastering the following distance between you and the car in front and minimizing unnecessary braking actions can also bring you fuel-saving happiness.

Extended data:

1, start slowly

In the process of starting, the vehicle should start at a low speed, lightly step on the accelerator and slowly speed up. This starting mode can not only shorten the heating time of the engine, but also effectively improve the fuel utilization rate, thus achieving the effect of fuel saving.

2, the throttle should be lightly stepped on?

Stepping on the accelerator hard will increase carbon dioxide emissions and greatly increase fuel consumption. Therefore, when driving, you should lightly step on the accelerator to avoid the instantaneous increase of engine speed and avoid the car trembling during driving, thus making the car more fuel efficient. ?

3. Shorten idle time?

Idle speed means that the car is stationary, but the engine is "chugging"-burning engine oil for nothing, which is a great waste. At this point, the mechanical function of gasoline combustion is consumed by the friction of internal parts. That is, work does not contribute. At the same time, if the idle time is too long, it will also increase the exhaust emissions.

4. Shift gears in time?

In the usual driving process, the same speed, if the gear is low, will often increase the engine speed and fuel consumption; If the gear speed is high but can't keep up, it will shift gears, which will damage the engine and increase fuel consumption, so shift gears in time when driving.
