The car needs to be refueled again, the gasoline is so expensive, the car can't afford it! Car owners are lamenting the price of gas, and the rise and fall of oil prices affect the hearts of every car owner. Some car owners are reluctant to drive every day because the oil is too expensive or trying to save fuel. Here are some tips on refueling your car to save energy and money.
Car fuel-saving tips
Don't turn on the yellow light.
We should check the oil meter before driving and calculate refueling on the way according to the distance of the trip and the scale of the oil meter. We can refuel in advance and not wait for the oil light to light up before refueling.
Because the oil pump is located in the fuel tank, the temperature of the oil pump is high when it is working continuously. And it can be effectively cooled by immersing in the fuel. The oil level is lower than the oil pump when the oil light is on. If you wait for the light to light up before refueling, the service life of the oil pump will be shortened.
If you drive more than 30,000 kilometers, you need to be more careful. When the oil is too small, once the oil pump pumps up the sediment at the bottom of the oil tank, it will be lucky if it just blocks the oil pump or blocks the oil circuit.
Suppose the car owner usually drives in the urban area. In that case, it is used for commuting to and from get off work, and it is more convenient to refuel, so there is no need to refill it at one time. A full fuel tank in a vehicle will increase its weight and fuel consumption. According to the current oil price, add 200 yuan or 25 liters of fuel at a time.
Increasing the grade of oil in the urban area does not save
The level of the gasoline grade only indicates the octane number of the gasoline, and the gas of different angles should be selected according to the engine's compression ratio. Mid-range cars with a compression ratio between 8.5 and 9.5 should generally use No. 93 gasoline; vehicles with a compression ratio greater than 9.5 should use No. 97 gasoline. At present, the compression ratio of domestic cars is generally above 9, and it is best to use No. 93 or No. 97 gasoline.
Vehicles are usually driven in urban areas, and the speed of the driving time is less than 60km per hour. There is no apparent benefit to adding 97 gasoline than 93 gasoline. When you run at a speed of more than 100km per hour for a long time, if you want the engine to function better, you should use 97 gasoline.
Refuel in the morning and evening with better quality
Refueling time is tricky. Under normal circumstances, the temperature in the morning and evening is relatively low, and the gasification point of gasoline is relatively low, so refueling should be selected in the morning and evening. Gasoline expands and contracts with heat, and gasoline is charged by volume. When the temperature is low, the gas density is relatively high. The mass per unit volume is rather large, and there is more fuel. The car owner can prepare a pair of stockings in the car's trunk. If the car owner is forced to refuel in a psychologically awkward place, putting the socks on the oil gun can effectively filter impurities.
Reminder: When refueling the car, you must choose the appropriate label according to the requirements. You can add as many numbers as you need. The higher the gasoline number, the better, but the one that suits your car.
Novices need to save fuel by following the following points.
1. Maintain optimal speed.
The most fuel is spent when accelerating, the smoother the driving, the fewer braking times, the fewer acceleration times, and the more fuel-efficient it must be. In addition, if the driver presses the accelerator, the fuel consumption may double as usual. The minimum economic driving speed is usually 50 to 60 km/h.
2. Avoid idling.
When the engine is idling, gasoline is also being consumed. When the engine reaches about 2000 to 3000 rpm, it should be shifted to high gear in time. If you are at an intersection with an exceptionally long red light. Or, if you need to wait for your companion to get off the car to do errands, you'd better turn off the engine and try to avoid idling the engine. The engine's fuel consumption idling for 3 minutes can make the car run 1 kilometer.
3. Pay attention to reducing the burden of automobiles.
Get into the habit of cleaning your car's trunk frequently. The extra stuff, whether it's a pair of sneakers or a half-can of oil, will add to the load on the vehicle. With an additional 45kg on the car, the fuel efficiency is 2% lower than a light car. Don't put anything on the roof. Wind resistance from a piece of luggage or a complete roof rack can reduce gas mileage by 5%. Put things in the car if you can.
4. Close the windows when driving on the highway.
After the speed exceeds 75 km/h, the car's fuel consumption will be 1.5 times that of the economical rate to overcome the air resistance. Open windows will hurt fuel consumption. In other words, turning on the air conditioner may save more fuel than opening the windows.
The following car habits will also increase fuel consumption
1. Step on and refuel
Stomping on the accelerator can be the primary cause of increased fuel consumption. Because many people like to enjoy the feeling of pushing back when refueling, they don't know that this is at the expense of multiplying the fuel consumption! The increased fuel consumption has no practical significance and does not run much, so if there is nothing urgent, try to drive at a constant speed. When accelerating, refuel slowly. When following the car, don't always rely on the brakes to adjust the pace and change the oil.
2. Driving at low speed and high speed
Those who make this mistake mainly refer to drivers who drive manual transmission models. They cannot handle the relationship between gears and vehicle speedwell, and they do not observe the engine speed. Therefore, they often step on the accelerator in low loads to accelerate, and sometimes the engine speed is even over 3500 rpm. Doing so wastes innocent gas. The correct way is to use the appropriate gear to match the corresponding vehicle speed. Under normal circumstances, when the connected equipment is engaged to accelerate and maintain a constant speed, the engine speed is more appropriate at 2000-2500 rpm.
3. Frequent paralleling
Some people drive and like to plug in whenever they see little free time. As everyone knows, frequent merging increases fuel consumption and quickly causes traffic accidents. In addition, the practice has proved that when the vehicle speed is at an economical speed of 80-90 km/h. it is the most fuel-efficient to drive at a constant speed in a straight line.
4. Frequent braking
Many people have a terrible habit: stepping on the brakes from time to time, even unconscious behavior. This affects the speed of the entire traffic flow and increases fuel consumption and vehicle wear and tear.
5. Speeding
Speeding mainly refers to when driving on the highway. As mentioned earlier, moving at a constant speed in a straight line is the most fuel-efficient. Of course, the vehicle speed should be at an economical speed of 80-90 km/h. Fuel consumption will significantly improve if it exceeds the economic rate, especially for small-displacement cars.
6. Blind modification
Blind modification is also a reason for the increase in fuel consumption. Many friends like to add accessories such as large surrounds, tail wings, winches, luggage racks, etc., to their cars after buying a car. These seemingly cool things invisibly increase fuel consumption because the fuel consumption will increase when the vehicle increases its weight. So it is recommended that all car owners and friends decorate their cars within a reasonable range. We have entered the misunderstanding of excessive decoration should Let's "reduce the burden" on the vehicle as soon as possible.
