How to increase your car's fuel consumption and how to refuel your car

My car has to be refuelled again. Gasoline is so expensive that I can't afford to keep it! Car owners are lamenting the price of gasoline. The rise and fall of oil price always affects the heart of every car owner. Some car owners are reluctant to drive because the oil is too expensive, or they try to save fuel. Here, I'd like to tell you a secret about how to refuel your car, so that you can save both gas and money.

The secret of car refueling

Don't put on the yellow light to refuel

"Before driving, the owner first looks at the fuel gauge. According to the distance of the journey and the scale of the fuel gauge, whether or not to refuel on the way can be calculated. The owner can refuel in advance, and do not wait for the oil lamp to come on."

Because the oil pump is located in the fuel tank, the temperature of the pump is higher when it is continuously working, and it can effectively cool down when immersed in the fuel. When the oil lamp is on, it means that the oil level is lower than the oil pump. If you wait for the light to come on every time, you will shorten the service life of the oil pump. If there is too little oil in the oil tank, the oil pump may be burned.

If you drive more than 30000 km, you need to be more careful. If the oil pump pulls up the sediment at the bottom of the oil tank when the fuel storage is too small, you will be lucky if you just block the oil pump or block the oil way.

If the car owner usually drives in the urban area, it is used for commuting and it is convenient to refuel. A full tank of oil will increase the vehicle's weight and fuel consumption. According to the current oil price, you can add 200 yuan or 25 liters of oil at a time.

No saving in urban area

The grade of gasoline only indicates the octane number of gasoline, so the gasoline of different grades should be selected according to the different compression ratio of engine. In general, 93 gasoline should be used for medium-range cars with compression ratio between 8.5 and 9.5, and 97 gasoline should be used for cars with compression ratio greater than 9.5. At present, the compression ratio of domestic cars is generally above 9. It is better to use 93 or 97 gasoline.

Vehicles usually drive in urban areas, and half of the driving time is less than 60km / h. adding 97 gasoline will not have obvious advantages over 93 gasoline. If you want to give full play to the efficiency of the engine, you should use No. 97 gasoline if you want to run more than 100km / h for a long time.

Better fuel quality sooner or later

Refueling time is a trick. In general, the temperature in the morning and evening is relatively low, and the gasification point of gasoline is relatively low, so refueling should be conducted in the morning and in the evening. Gasoline has the property of thermal expansion and cold contraction, and gasoline is charged by volume. When the temperature is low, the density of gasoline is relatively high, the mass per unit volume is also relatively large, and there is more refueling. The owner can prepare a pair of silk stockings in the trunk of the car. If the owner is forced to refuel in the mental place, the silk stockings on the oil gun can effectively filter impurities.

Warm tips: you need to choose the right label according to the requirements. You can add as many sizes as you need. Gasoline is not the higher the label, the better, but the car that suits you.

Novices need to save fuel and follow these points

1. Maintain optimal speed. The more stable the driving, the less braking times, the less acceleration times, and the more fuel saving. In addition, if the driver presses the accelerator to the bottom, the fuel consumption may reach twice as much as usual. The lowest economical driving speed is usually 50 to 60 km / h.

2. Avoid idling. When the engine is idling, gasoline is also consumed. When the engine reaches about 2000 to 3000 rpm, it is necessary to shift up the gear in time. If you are at an intersection with a very long red light, or if your companion gets out of the car for business, you need to wait. At this time, you'd better turn off the engine and try to avoid idling. The fuel consumption of the engine idling for 3 minutes can drive the car for 1 km.

3. Pay attention to lightening the load of cars. Develop the habit of cleaning the trunk of your car regularly. Extra stuff, whether it's a pair of sneakers or half a can of oil, will add to the weight of the car. The fuel efficiency of the car is 2% lower than that of a light vehicle. Don't put anything on the roof. A piece of luggage or a full roof rack creates wind resistance, which reduces the gas mileage by 5%. Put things in the car if you can.

4. Close the windows while driving on the freeway. When the vehicle speed exceeds 75 km / h, in order to overcome the air resistance, the fuel consumption of the vehicle will be 1.5 times of the economic driving speed. Open windows will have a negative impact on fuel consumption. In other words, turning on the air conditioner may save fuel than opening the windows.

The following habits can also increase fuel consumption

1. Step on the gas

Slamming on the gas pedal can be said to be the primary cause of rising fuel consumption. Because a lot of people like to enjoy the feeling of pushing back when they are in a rush, but they don't know that this is at the cost of doubling the fuel consumption! The increased fuel consumption is of no practical significance, and they don't run much. So if there is nothing urgent, try to drive at a constant speed. When accelerating, you should add oil slowly. When you follow a car, don't always rely on the brake to adjust the speed. You should try to adjust it by collecting fuel.

2. Low gear and high speed driving

This mistake is mainly made by drivers who drive manual transmission vehicles. They can't handle the relationship between gear and vehicle speed, and they can't observe the engine speed. Therefore, they often step on the accelerator to accelerate when they are in low gear. Sometimes the engine speed even exceeds 3500 rpm. It's a waste of innocent gas. The correct way is to use the appropriate gear to match the corresponding speed. In general, when the gear is put into the corresponding gear to accelerate and maintain a constant speed, the engine speed at 2000-2500 rpm is more appropriate.

3. Frequent merging

Some people like to drive as long as they see it. However, frequent line merging not only increases fuel consumption but also easily causes traffic accidents. In addition, the practice has proved that when the speed is between 80-90 km / h, it is the most economical to drive in a straight line.

4. Frequent braking

Many people have a bad habit, that is, they have to step on the brake from time to time, or even act unconsciously. This not only affects the speed of the whole traffic flow, but also increases the fuel consumption and vehicle wear and tear, which is harmful and unprofitable!

5. Speeding

Speeding mainly refers to driving on the highway. As mentioned above, even driving in a straight line is the most economical. Of course, the speed should be 80-90 km / h. If it exceeds the economic speed, the fuel consumption will be greatly increased, especially for small displacement vehicles.

6. Blind refitting

Blind refitting is also one of the reasons for the rise in fuel consumption. After buying a car, many friends like to add accessories such as large enclosure, tail wing, winch, luggage rack and so on. These seemingly sleazy, in fact, virtually increase fuel consumption, because every increase in the weight of the vehicle, the fuel consumption will rise accordingly. Therefore, it is recommended that all car owners decorate their cars within a reasonable range. Those who have entered the error zone of excessive decoration should "reduce the burden" of their cars as soon as possible.
