I always feel that my car is more fuel efficient, what are the ways to save fuel?

1. Follow the methods recommended in the car maintenance and repair manual——— a well-maintained car is more fuel-efficient to drive, dirty spark plugs, dirty air filters or clogged filters will reduce fuel economy.

2. Keep the tire pressure at an appropriate level——— if the tire pressure is too low, it will cost more fuel, so you need to check the tire pressure frequently. Tyre pressures that meet the required requirements can reduce fuel consumption by one percent.

3. Reduce the burden on your vehicle——— overweight vehicles will consume more fuel when driving. Therefore, try to empty the suitcase, do not use the trunk as a storage room, and do not pile up non-essential items in the car. If you don't use your luggage or ski rack, remove it.

4. Don't drive too hard——— step on the accelerator after parking, and press the brakes hard and accelerate sharply, these behaviors will increase fuel consumption.

5. Try to hang high gear——— low gear will consume more energy, so when driving a car with a manual transmission, you should change to a high gear in time after the speed stabilizes, and try to avoid using the "sport" mode when driving a car with an automatic transmission.

6. The use of cruise control ——— on flat roads can be used to save fuel, but this method is not the most economical on steep terrain.

7. Keep your vehicle clean——— frequent car washing and waxing can reduce air resistance, which can improve fuel economy.

8. Avoid letting the car idle for a long time——— the vehicle will also consume fuel when the engine is idling. If possible, try to turn off the engine while you stop and wait, and don't let it spin all the time.

9. Try to use air conditioners as little as possible——— air conditioners can consume a lot of fuel. Opening the windows on both sides can reduce air resistance, so you should open the windows when you are driving slowly in traffic jams, and turn on the air conditioning when driving at high speeds. (Opening windows at high speeds can increase drag).

10. Accelerate after warming——— it is more fuel-intensive for the engine to run at low temperature than after the temperature rises, so don't accelerate immediately when you start it, but slow down for a few minutes to let the engine heat up and then accelerate.

It's been a full 14 years from 05 to now, not to mention 70,000 kilometers, which is a bit unbelievable. There are so many factors that affect tire pressure. Driving habits, tire pressure, and more. If you are a veteran driver, these should not be difficult for you.

What worries me is that the car is not more than 7 years old, and the piston rings are worn out so badly that the opening gap becomes very large.

Don't refuel violently at the start, stabilize the clutch and then lightly step on the accelerator to start. You can not turn on the air conditioner at low speed, but you can not turn on at high speed. The window goes to Anu to open that the car has resistance, and it will also consume fuel, even more fuel than turning on the air conditioner, and when driving, use the accelerator"Plus, pine, plus.

The method is more fuel-efficient"The last way is to speed up to 5th gear and accelerate up"Pay attention to press go! "..Coast in neutral mode.

Just don't drive.

There are several reasons for this problem.

First: driving habits are not good, drill when you see empty, stop and brake urgently, hang low gear and open high speed and other habits will lead to a car is very fuel-efficient, if you want to be more fuel-efficient, you can try to maintain a constant speed, relying on inertia brake lights.

Second: engine carbon deposits, the engine will also cause high fuel consumption after carbon deposits, you might as well buy carbon cleaning car supplies to clean up the carbon deposits of the engine, so that the car is not so fuel-intensive.

Third: the tire pressure is low, the tire pressure of the wheel is too low and the wheel inflation is not enough will also cause the car to be very fuel-intensive, you may wish to detect the wheel inflation problem when driving, and the tire pressure can also be detected by the instrument, and the timely inflation of the wheel will reduce fuel consumption.

Fourth: the trunk is too heavy, the trunk will put too many items will also make the car very fuel-intensive, clean up the trunk items in time to throw some unnecessary things down, for the car to shoulder it naturally is not so fuel-intensive.

Fifth: engine wear and spark plug failure will also cause the car to cost fuel, you can check whether your car has these two problems.

Sixth: If the car is not hot, not only will the engine be easily worn out if it is not heated before driving in winter, but also the car will be very fuel-intensive. Therefore, it is best to warm up the car before driving in winter, do not drive in a hurry but idle in place for a minute, and after normal driving, you should also keep a low speed first, and then slowly stop the speed.

If none of these are available, then you can see if the oxygen sensor is broken, the clutch is slipping, and so on.

Moreover, after a few years of use, the engine wears out, and the mechanical group is aging, and the car will consume more and more fuel as it drives. Usually develop good habits, regularly go to the 4S shop for maintenance, and clean up the engine carbon deposits will reduce fuel consumption

Clean the oil circuit, develop good driving habits, and change to a small displacement car or new energy vehicle.

Isn't it time to clean up when the life is up. Spark plugs, throttle valves, sensors, filters, etc.

As long as the car is not driving in ideal working conditions, fuel consumption is relatively high, and when the car is driving at economic speed at operating temperatures, fuel consumption is the lowest. 1.Short-distance low-temperature driving:

The engine is a hot engine. The engine must be warmed up before reaching operating temperature. In the low warm-up state, the ECU must control the concentrated injection, which can generally reach more than twice the ideal working condition.

However, many people use the car for too short a mileage, and often the hot car turns off before it is finished. At this time, the fuel consumption will naturally be higher. 2.

Low-speed congestion: When the car is driving at low speed, one foot on the accelerator and one foot on the brake. At this time, the inertia of the engine is relatively large, and the power required to overcome the resistance in an instant is also relatively large.

At this time, the fuel consumption of the engine is also relatively high. 3.Ultra-high-speed:

When the car is driving at ultra-high speeds, the air resistance increases exponentially. At speeds above 120 km/h, more than 60% of the engine power is used to overcome drag. When the car is driving at high speed, the rolling resistance of the tires is also relatively large, and the fuel consumption is also relatively high at this time.

4.Overload and overload: When the car is overloaded, the downforce is relatively large and the rolling resistance increases.

Especially when accelerating and braking repeatedly, the inertia is greater, and the fuel consumption is higher at this time. How to determine the economical speed of your car? In the case of a manual transmission, the lowest speed of the state air in which the car runs stably in the highest gear is the economic speed.

Pay attention to the smooth operation and low noise of the engine leakage. If it's automatic, if it's equipped with manual mode, switch to manual mode and manually upshift. The highest speed that can be turned up is the economy speed per hour.

How do you save fuel while driving? 1.Minimize short-distance driving at low temperatures.

2.Increase your speed to the economical speed range as soon as possible while driving. Usually this speed return limb range is 60-90km h, the larger the basic displacement, the higher the economic speed.

3.Try to keep the throttle steady while driving to avoid unnecessary acceleration and deceleration. 4.

Don't change lanes frequently unless necessary. Changing lanes will increase the distance traveled. 5.

If it's not necessary, try to brake as often as possible and learn to use engine drag to control the car's natural deceleration.

Whether a car is fuel-efficient or not is not only related to the owner's daily driving habits, but also a key reason for whether the car is maintained. Good maintenance not only keeps the car's paint beautiful and shiny with a high hood, but it also saves fuel. As soon as your engine starts, your gasoline will burn.

So even if your car doesn't move, your gas will be wasted if the engine is still running. Many people like to put their car in n-gear while waiting and turn on the air conditioner**. They liked it very much.

In this idle environment, your fuel consumption will go up. For those who need to wait for more than 2 minutes, in addition to the traffic light, put on P gear, pull the handbrake, lower the window, then turn off the engine and wait slowly. Firstly, a breath of fresh air, and secondly, it can really save a lot.

Poor driving habits, such as empty drilling, emergency stopping and braking, driving at low speeds and high speeds, etc., can lead to a lot of fuel consumption. If you want to save more fuel, you can try to drive at a constant speed and rely on inertia brake lights. The engine has carbon deposits, and the engine fuel consumption will be too high after carbon deposits.

You might as well buy some car supplies to clean the carbon deposits on the engine, thereby reducing the fuel consumption of the car. Low tire pressure, low tire pressure, and under-inflated wheels can also cause cars to consume a lot of fuel. When driving, you may wish to check the inflation of the wheels first, and the tire pressure can also be detected by the instrument.

Inflating the wheels in time will reduce fuel consumption.

The box is too heavy. Putting too much stuff in the trunk can also make the car very gas-guzzling. Clean up the trunk in a timely manner and leave something unnecessary.

It naturally doesn't consume as much fuel for your car. Engine wear and spark plug failure can also contribute to fuel consumption. You can check your car for these two issues.

There are no hot cars. If the car is not hot before the winter drive, it will not only cause the engine to wear out easily, but also consume a lot of fuel. So before driving in winter, it's best to warm up your car.

Don't drive in a hurry, drive at idle speed for one minute. After normal driving, you should also keep your speed low first and then slowly stop it.

You can turn on the air conditioner less when driving, you can also use less electrical appliances, and you can also quietly pay attention to your own operation when driving, and you should also pay attention not to step on the brakes and step on the accelerator sharply, so that you can save fuel.

The first point is that if you want to save fuel, you should pay attention to the slag when you start, and the second point is that you should do it regularly to clean and store things quietly, so as to avoid unnecessary dangers in the car, and regular inspections will also save fuel consumption.

You can clean up the carbon deposition of the engine, you can also bend the lead to clean up the spark plug, and then you must maintain the car in time, change the oil, you can maintain a constant speed, you must control the speed, and the start should be soft and buried. Lack of friends.

Choosing the right way of driving, you can repair the vehicle, so that you can solve the problem well, be sure to check the specific situation of the engine.

To start slowly, do not immediately accelerate the bridge, pay attention to choose the right gear, avoid sliding in neutral gear, reduce frequent lane changes, and pay attention to the sensitive limbs in daily life to do good maintenance in Zhenzhou.

It is mainly related to the displacement of the car, the fuel consumption of 100 kilometers, and the current oil price.

The specific analysis is as follows:

1. Fuel consumption per 100 kilometers refers to the fuel consumption of a vehicle driving 100 kilometers on the road at a certain speed. It is a theoretical indicator of the vehicle. The theoretical fuel consumption is usually 90 km/h for 100 km.

2. Displacement (sweptvolume), a special term for hydraulic transmission, refers to the volume of fluid sucked in or discharged per stroke or cycle. Generally speaking, the larger the displacement, the higher the fuel consumption per 100 kilometers. But there can be no formula between the two, at least not the driver's handling.

However, the following factors can be used as a relatively large weight as a reference for fuel consumption: displacement; curb weight; Full load mass; Actual working conditions of the engine**speed, output torque); Road conditions can be reflected by the real-time parameters of the engine.

For example: 1. Local oil prices. In addition, 92 gasoline is not the same as 95 gasoline**.

2. The fuel consumption of the car itself does not have a fixed data. Objective factors such as the technical condition of the engine, the calorific value of gasoline, the resistance of the transmission system, the air pressure of the tires, the type of road and the degree of congestion, the drag coefficient of the whole vehicle, the driving speed, the weight and load of the vehicle, and the driving skills of the driver will affect fuel consumption.

Especially when driving in urban areas, all kinds of traffic lights, traffic jams, and cars stop and go, and can't run. For the same distance, the fuel consumption must be more than that of running at high speed, and the fuel cost will be correspondingly more.

3. The difference in car displacement. The fuel consumption of small displacement cars mainly depends on the weight of the car, and has little to do with the displacement itself. Cars with more than displacement are more affected by displacement factors.

For example, 8 oil per 100 kilometers is 8 liters of fuel per 100 kilometers, and 8 100 is the fuel consumption of one kilometer, that is, the fuel consumption of one kilometer is liters.

If you want to calculate how much it is, just multiply the fuel consumption of one kilometer by the price of gasoline. Coincidentally, for example, 92 gasoline is 8 yuan, which is yuan.

Fuel-efficient tips for driving:

1. The safest and most fuel-efficient driving method is to drive in a straight line at a constant speed. The most fuel-efficient low-displacement cars are 60 to 80 kilometers per hour, and medium-duty vehicles are 80 to 100 kilometers per hour.

2. Try to control the shift speed and active gear, start as low as possible when starting, slow down the accelerator pedal, and accelerate the steam.

3. Raise the throttle as much as possible to save fuel and minimize braking. Because the car consumes energy, you should increase the throttle in advance when going downhill through an intersection.

4. If the road is congested and the front car brakes frequently, you should keep enough following distance from the car in front, which can reduce the number of braking times and save fuel.
