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

I believe that many car owners have a good habit of warming up their cars in the morning, but just waiting for the speed to drop to normal or the water temperature to rise to normal is tantamount to having a hard time with their wallets. According to this suggestion, car owners in most parts of China can shift gears for about half a minute after the vehicle is started, and drive at 1 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 commuting 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.

Experts say that insufficient tire inflation 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 waste more oil. Similarly, if the same displacement, the same model, the same load and other cars. Assuming that car A uses original tires and car B uses wider tires, car B will consume more fuel than car A because of the increase of vehicle driving resistance. Of course, if the owner inflates the tires in Dachuan and replaces them with narrow tires, it will increase the possibility of puncture and eccentric tire wear and reduce driving comfort.

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. Because the start and stop of vehicles are reduced, driving at an economical speed is equivalent to saving fuel. Also, many car owners often change lanes on the road. At this time, they not only have to accelerate and decelerate, but also the driving distance is not as short as the straight line distance, so this is also one of the reasons for the increase in fuel consumption.

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

Conditional friends suggest cleaning the appearance of vehicles frequently and waxing regularly is also a good fuel-saving method. 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. When idling for a long time, don't turn off the engine or strike a light frequently.

When waiting for a long time without moving the vehicle, it is suggested that the owner 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.

While waiting for friends and traffic jams, you might as well turn off the engine. Whenever the engine is started, there will be more computer-controlled fuel injection, so starting the engine frequently for a period of time will definitely increase the fuel consumption of the vehicle. Auto repair experts also said that starting the engine frequently is a sign of "car abuse".

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

I advise you to watch a movie. It is very undesirable to step on the accelerator with your big feet before you start. After all, the stop line is not the starting line of the track. 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 from the preceding car and minimizing unnecessary braking actions can also bring fuel-saving happiness.

7. The vehicle increases the load without reason.

Many friends who just bought a car like to put all kinds of decorations and exterior parts on the car, and even worse, they simply moved their offices and homes to the car. Blindly installing large enclosures, tails, winches and luggage racks on the vehicle will also increase the fuel consumption of the vehicle. The fuel consumption of vehicles will increase with each additional weight, so it is suggested that car owners decorate their cars within a reasonable range. Friends who have entered the misunderstanding of over-decoration should "reduce the burden" on their cars as soon as possible.

8. The oil is not filled according to the specified label.

The viscosity of engine oil is the main index of engine oil. For example, 15W-40, where "w" stands for winter, and the smaller the number in front of it means that the viscosity of engine oil is thinner, the fluidity is better, the available ambient temperature is lower, and the engine protection ability is better during cold start. The number after "W" is the index of high temperature resistance of oil. The larger the number, the better the protective performance of oil at high temperature. Too much choice of engine oil with high viscosity will increase the resistance of engine parts, which will not only consume power, but also increase fuel consumption.

9. Driving at low speed or high speed.

This situation may happen to many novice drivers. Many times, the speed is already very high, and there is no corresponding upshift. Then, with the increase of engine speed, fuel consumption naturally soared. In this regard, we may wish to refer to the reasonable speed and gear of the vehicle to choose the appropriate shift timing. The other is that the speed is too low, but the gear is still high. The most obvious feature of this situation is that the engine and body have started to shake and may turn off at any time. At this time, some friends will choose to increase the throttle, and increasing the throttle means increasing the fuel injection. The best solution to this situation is to downshift.

10, the windows are fully open in summer, and the air conditioner is turned on in traffic jams.

In summer, people in air-conditioned cars will naturally feel much more comfortable, but with the increase of engine load, fuel consumption will also increase. At this time, some car owners choose not to turn on the air conditioner and open all the windows to cool down, but the driving resistance increased by opening the windows when the vehicle is driving will even be greater than the power consumption of the air conditioner compressor, so it is appropriate to open the windows to cool down at low speed, and it is more cost-effective to turn on the air conditioner at medium and high speed. Also, the fuel consumption of vehicles in traffic jams will increase. If the air conditioner is turned on ... so if the temperature is acceptable in traffic jams, car owners who want to save fuel might as well turn off the air conditioner.
