10 fuel-saving tips for driving.

1. Pedal lightly when starting and braking,

Don't push too hard.

Never neglect car maintenance. Dirty air and oil filters, worn spark plugs and faulty emission control systems may increase fuel consumption. In order to maintain the best performance of the car, it is best to change the oil every 5000 kilometers and check the filter.

3. Pay attention to tire maintenance. Low tire pressure is not only dangerous but also harmful to the engine. Excessive tire deviation or wear may increase fuel consumption.

4. Use gasoline recommended by automobile manufacturers.

5. Use the air conditioner in the car reasonably. When the weather is hot, it is best to park your car in the shade; After getting on the bus, open the window for a few minutes.

6. Reduce the items stored in the suitcase.

7. Plan the travel time reasonably to avoid the peak period.

8. Reasonable planning of tourist routes.

9. Pay attention to the driving speed. Generally speaking, when the speed is 88.5 kilometers per hour, the fuel consumption will increase by 15% when the speed is increased to 105 kilometers, and it will increase by 25% when the speed is10 to 120 kilometers per hour.

10. Come in the morning. In the morning, the temperature is relatively low and the gasoline density is high, so the same price may make you get more gasoline when you refuel.

Fuel-saving magic weapon

Magic weapon one: warm the car before starting it.

When the temperature is low in winter, there is obvious difference in fuel consumption whether the car is "warmed up" before starting. Generally speaking, the car should be warmed up for one to three minutes before going out in winter, and the water temperature should reach 40℃ before starting. And let the car run stably 1 to 2 kilometers and then accelerate. This can reduce fuel consumption and is also good for the engine and parts of the car.

Magic weapon 2: soft start

Start at a low speed, step on the accelerator slowly, and accelerate slowly. When the car reaches a certain gear speed, learn to listen to the sound of the engine to gradually change from low gear to high gear. This can reduce the heating time of the engine and improve the utilization rate of fuel. If you burst the throttle to accelerate at the beginning, it will not only hurt the car, but also greatly increase fuel consumption.

Magic weapon 3: use economic speed

The economic speed of an ordinary car is between 60 km/h and 80 km/h, and the car is the most fuel-efficient at the economic speed. Whether the speed is too high or too low, it is not conducive to fuel saving. When the vehicle speed is low, the movement speed of the piston is low and the combustion is incomplete. When the vehicle speed is high, the increase of intake speed leads to the increase of intake resistance and fuel consumption.

Magic weapon four: gently lift the throttle

Lightly lifting the throttle can save fuel. If the throttle is suddenly raised, the engine speed will suddenly decrease to play a drag role, offset part of the driving inertia, and make the car "vibrate", thus increasing fuel consumption.

Magic weapon five: shift gears in time

Shift gears quickly and timely, especially when driving on slopes. The shorter the shift time, the better the dynamic performance of the car, which can save more fuel. If the shift is not timely and the hands and feet are not well matched, the fuel consumption will increase greatly.

Magic weapon six: reduce the use of brakes

Braking is essentially a process of energy conversion, and braking means energy consumption. Therefore, when crossing the intersection and going downhill, you should increase the throttle in advance. If the car has good performance, you can also put neutral to let the car slow down naturally, so as to achieve the purpose of "replacing the brake with slip".

Magic weapon seven: keep your distance from the car

If the road is congested, the front car often brakes, and it is necessary to keep enough distance from the front car, so as to slow down calmly, reduce the number of brakes and achieve the purpose of saving fuel.

Magic weapon eight: high gear driving saves fuel

Generally speaking, try to use high-speed gear and less mid-range. In an urban road like Guangzhou, when the speed reached more than 40 kilometers at that time, it was enough to change the fifth gear.

Of course, don't drive high. Learn to listen to the sound of the engine to shift gears and understand the situation of your car. When the engine is going to "tremble", it is necessary to downshift, let the speed go up and change back to high gear.

Magic weapon nine: learn to slide safely

When a car is driving, it keeps neutral to continue driving by the kinetic energy of the car itself or the potential energy of downhill. This is called taxiing. When taxiing, the engine usually runs at idle speed, and the engine only consumes a little oil, so taxiing is a fuel-efficient operation mode.

Coasting can be divided into acceleration taxiing, deceleration taxiing and downhill taxiing. Accelerated taxiing means accelerating first on a flat, wide and straight road with few pedestrians and vehicles. When the speed reaches a certain value, put in neutral and use the inertia of the car to drive. If the vehicle has good acceleration performance, short acceleration time and low fuel consumption. Accelerating the taxiing process is the fuel-saving process. Deceleration and taxiing refers to the method of shifting into neutral in advance when deceleration is needed, and taxiing is used instead of braking. The power consumed by unnecessary braking is reduced, which not only saves oil, but also reduces the wear of parts. But you must ensure safe driving. Remember not to slide in neutral after snow and rain.

Special reminder

Pay attention to the water thermometer when the car is driving, and the normal water temperature of the engine should be kept between 80 ~ 90℃. Too high or too low will increase fuel consumption. Especially if the water in the water tank is insufficient, the water temperature can easily rise rapidly. When the water temperature exceeds 95℃, the oil consumption will increase by 30% ~ 40% compared with the normal temperature, and it will easily lead to the wear and damage of parts.

At the same time, if you feel that the car has insufficient power, stop to see if there is a flat tire. If the tire pressure is too low, the fuel consumption will increase obviously.

Regularly check the level of lubricating oil and oil, and replace the lubricating oil and oil as planned.

Maintain the engine, choose lubricating oil and remove carbon deposits, and repair it immediately if there is any problem. Because no matter how big or small the problems are, they will reduce the efficiency of the engine and waste your gasoline.

Regular replacement of air and oil filters will affect fuel consumption;

Keep wheel balance, and regularly check the tire tread to see if there is uneven wear. At the same time, it depends on whether there is any sharp object embedded in the tire, which will cause slow air leakage.

Always check the tire pressure to keep it in the best condition. Make sure the tire pressure is correct. Insufficient gas or too much gas will increase fuel consumption, so check the tire pressure regularly. As long as one tire is less than 40 KPa, the life of this tire will be reduced by 65,438+00,000 kilometers, and the total fuel consumption of the car will increase by 3%.

Don't change the size of the tire at will. Choosing wider tires may make your car look more "sports car", but the wider the tires, the greater the wheel resistance, which will waste gasoline money. Use the lowest viscosity engine oil. Your car manual should state the minimum oil viscosity that your car can use. The lower the viscosity of engine oil, the more "labor-saving" the engine will be, and the more fuel-efficient it will be. Don't warm up too much. Some car owners like to warm up before driving in the morning, which is a good habit. But preheating for too long is undoubtedly a problem in your pocket. Besides, you can actually slow down the car for a kilometer or two to warm up.

Don't start the car when it is stationary. If you need to wait in the car for a while, turn off the engine Don't slam on the accelerator to accelerate. This will only greatly increase fuel consumption, but it will not save you much time.

Don't overspeed. For ordinary cars, 80km/h is the most fuel-efficient speed. Every time you increase 1km/h, your fuel consumption will increase by 0.5%.

Clean the trunk of your car. Extra things, whether it is a pair of sports shoes that are rarely used or half a can of used engine oil, will increase the burden on the car, that is, the burden on your pocket.
