When is the best time to refuel your car and when is it good to refuel your car?

It is generally not advisable to refuel your vehicle during the midday hours. Because the cost of refueling is calculated according to the volume, due to the thermal expansion and contraction, the volume of gasoline will increase with the rise of temperature, and the volume will also decrease when the temperature drops. Therefore, choose to refuel in the morning or evening to add more oil.

Car owners need to pay attention when refueling, if they usually drive in the city, they don't need to go far away, and the amount of refueling each time only needs to be four-fifths of the fuel tank. Since there are gas stations in many places in the city, it is convenient to refuel. And the vehicle does not need to carry too much gasoline, so as to reduce the weight of the vehicle, avoid the engine overload, and play a fuel-saving effect.

At present, the sales of fuel at gas stations are settled by volume (liters), and the fuel density is related to temperature, because the temperature in the morning and evening is lower than that during the day, the density of the oil is larger, so the choice of refueling in the morning and evening will theoretically take a little "cheap".

2.The time should be good morning, when there is less vapor in the fuel tank, if the car is very hot, the gas is too big, it is not easy to add, and now the good car is generally very well sealed, and the gas is not easy to disperse.

Choose the right time to refuel. If you don't refuel at noon, due to thermal expansion and contraction, the volume of gasoline will increase with the increase of temperature, and when the temperature decreases, the volume of gasoline will decrease.

For example, the temperature of the underground oil storage tank of the petrol station is at its lowest from 5 a.m. to 8 a.m. (from 9:30 a.m. to 9:30 a.m. in summer (spring, autumn and winter), at this time, because gasoline is charged by volume rather than by weight, the volume will be affected by the temperature of thermal expansion and contraction.

When refueling in the morning or evening, the same volume of gasoline can have more mass, and it can save a lot of money after a long time of accumulation. Try to refuel in litres and never in how much money you refuel, because you will often lose your money invisibly after rounding.

How much to refuel or according to the actual use of the car, such as using the car to drive a long distance, or basically keep using the car every day, then you can consider filling up the fuel is the best, which can reduce the distance and effort of frequent refueling, which is a more cost-effective method.

But it doesn't mean that there are no disadvantages when filling up, filling up the fuel will increase the weight of the car, fuel consumption will increase, and adding too slowly, the weather is too hot, it may have a certain impact on the car.

So let's take a look at adding half, generally speaking, half of the fuel may not be able to help the owner for a long time, if on the way, fuel consumption suddenly bottoms out, may not only cause the car to fail, but also may have a certain impact on the car.

1. It is better to refuel in the morning or evening, so as to avoid the expansion of the car caused by the strong sun at noon. Gasoline is charged by volume, not by weight, and expands and contracts in heat. When refueling a car in the morning or evening, the same volume of gasoline can have more mass, and it is easy for a tank of fuel to run dozens of kilometers more.

2. If you are mainly driving in the city, it is best to fill half or two-thirds of the tank each time. Because driving in the city often has to stop and go, if you fill up the fuel tank will increase the load on the car engine, the start is weak and the vehicle consumes fuel, and there are many gas stations in the city, not afraid of having no place to refuel.

3. Do not refuel the car more than the upper limit of the fuel tank. This is because when the oil is filled, it is easy to volatilize into the atmosphere and cause air pollution, which not only causes waste, but also causes harm to the air, and may also damage the engine or catalytic converter.

From the bidding of a project to the commencement of the project, all parties to the project should make corresponding HSE commitments and establish corresponding HSE responsibilities, and the project owner should always take HSE management as an important task.

In this way, the "safety first" has been formed in the minds of all employees.

1. The concept of "prevention first" makes employees aware of the importance of HSE work and lays a good foundation for future work. Establish integrated HSE management. First, HSE risk management technology and management system are integrated, and scientific and effective management technology is used as the support to ensure the implementation of the corresponding management system; The second is the integration of HSE management and the project development process.

HSE risk exists throughout the construction process of a project, so it is important to focus on comprehensive HSE management throughout the project and improve it as the project progresses, rather than as a phased approach. In order to implement the safety production responsibility system, the Yuji Project Management Department set up an HSE management committee at the beginning of its establishment, and issued management documents such as "Quality and HSE Reward and Punishment Measures", "QHSE Work Arrangement", "QHSE Punishment Implementation Rules", "Safety and Civilized Construction Regulations", etc., requiring all construction units to implement safety.

1.It is better to refuel in the morning or evening and avoid the sun at noon. Because gasoline is charged by volume, not by weight, thermal expansion and cold contraction. When refueling in the morning or evening, the same volume of gasoline can have more mass and save a lot of money - a tank of fuel can run tens of kilometers more.

I hope you can give a thumbs up.

Of course, it's better when the runners are nearing the finish line and the race is about to end.

It is best to call the police to refuel the car, and too low the fuel level will cause the gasoline pump to burn out. The remaining amount of oil should not be too high, as frequent refueling will increase the number of trips to the gas station and cause waste. You can choose to refuel in the morning or evening, and you should avoid refueling when the sun is toxic at noon and the temperature is high.

Because gasoline is charged by volume, not by weight, volume is affected by temperature, thermal expansion and contraction. When you go to the gas station to refuel, you should turn off the ignition, and don't answer the phone to play with your phone, and don't use an open flame in the gas station. When refueling at ordinary times, you must choose a gas station with better oil products, do not go to some gas stations with poor oil products, if you use gasoline of poor quality for a long time, it will lead to an increase in carbon deposits in the engine.

Temperatures are lowest at 9:30 a.m. (spring, autumn, and winter), when volume is affected by temperature because gasoline is charged by volume, not by weight.

fees.

In recent years, many manufacturers have basically used &ldquo petroleum products to prevaricate their partners with problems, and transfer part of the responsibility for questioning the quality of the body to the oil products. The quality of oil products at gas stations directly under Sinopec and PetroChina is guaranteed. Never try to refuel cheaply at a small gas station.

At the same time, it is necessary to keep the invoice. In case of an accident, this is your credential. Cheap and trusting some of the so-called low-cost gasoline is not a long-term solution, and when the engine does have oil problems, you will regret it.

00 (hot weather) and 5:00 to 9:30 a.m. (spring, autumn, winter) are the lowest.

At this point, since the gasoline is filled by volume rather than weight, the volume expands and contracts due to temperature. When refueling in the morning or evening, the same volume of gasoline can have more quality, and you can save a lot of money over time.

4.After production, add half of the car's fuel tank or 2 to 3 to the downtown area.

Because driving in urban areas often stops, if the car tank is filled, the load on the engine will be heavier, the start will be ineffective, and the car will consume fuel. And there are quite a lot of gas stations in the city, so don't worry about not finding a gas station.

5.If the car rarely drives, it is advisable to keep the fuel level low.

6.If you find one tanker, find the next one.

Because the fuel replenished by the fuel dispenser will accumulate at the bottom of the tank for many years and will likely be added to your car's fuel tank. If these impurities enter the engine cylinders, it will affect the life of the engine.

Although gasoline is stored underground, it may have the necessary leakage after prolonged use. After a rainstorm, rainwater that cannot be discharged may leak into the fuel tank and also affect the life of the car's engine.

1) Turn off the engine.

2) No smoking.

3) Don't use your phone – leave it in the car or turn it off.

Well, that's all for a brief introduction to when it's good to refuel your car today. I don't know if my friends have any further understanding of when to refuel the car. I hope the introduction of Bian Xiao car can be helpful to friends.

Cars are already a must-have tool for everyone to get around. Of course, automotive knowledge is essential. In order to facilitate everyone to understand this knowledge, today Bian Xiao will introduce to you the best question of when it is best to refuel the car.

Interested friends can learn about it, it may be helpful to you.

When is the best time to fill up your car? Many people think they are refueling when the fuel gauge is on, because there should be a lot of oil in the car's fuel tank at that time. But this can easily damage the oil pump.

Most of the time, when the oil lamp is on, it means that the oil level is lower than the oil level of the oil pump, and the oil in the car's fuel tank is basically used up. When the amount of oil is too small, the residual sediment at the bottom of the car fuel tank will be pumped up for fuel, which is easy to cause oil blockage or oil pump blockage. Then it is advisable to refuel when the fuel gauge indicates that there is 1 4 oil left.

This is the misunderstanding of many friends. It is important to know that the grade of gasoline is only the proportion of the octane number of gasoline. For example, No. 95 gasoline, isooctane is about 95%, and n-heptane is about 5%.

Because isooctane has good knock resistance and n-heptane has poor knock resistance, the higher the label and the higher the octane number, which means that the gasoline has better knock resistance. We recommend filling according to the car instructions or the recommended sign on the inside of the car fuel tank cap. It's good to be suitable, and there's no need to blindly pursue it.

Many friends basically live in the habit of filling up the fuel tank of the car directly or adding it to the jump gun. However, it is quite dangerous to do so on a hot day. Too much oil will swell and spill due to the principle of thermal expansion and cold contraction.

At the same time, too much oil can cause damage to the canister, and excess gasoline will flow into the canister with fuel vapor, causing damage. The carbon canister is damaged, it cannot filter the gasoline vapor, and the gasoline will be introduced into the body, which is also dangerous.

The car is a very good means of transportation for each of our owners, which brings great convenience to our travel. However, I believe that many car owners have such a question, that is, when is the best time for our car to refuel? After all, Mingqin's postage is very expensive now, and if something goes wrong with your home, it will bring us a certain amount of economic pressure.

Depending on the model of our car, the volume of its fuel tank is also different. The mailbox of the large car will be relatively larger than that of Rongji, and the car itself has a large amount of acacia oranges. Then, in some operating instructions, it will be written that you can refuel when you have a quarter of the fuel left in the tank.

If there is too little oil, it will affect our travel, and even affect the cooling effect of our car, so if our car is driven for a long time.

Well, if we have more than 1 4 gasoline in our tanks, it is clearly not appropriate to refuel at this time. Why? Because this will increase our mileage and make us consume more and more fuel, this statement may be difficult for many people to understand.

Of course, some people only refuel when our tank indicator light is on. Is this the most appropriate situation? When I talked to the mechanic again, he told me that it was actually appropriate to refuel when the light in our tank was on.

Then we usually have to be cautious 10 points when driving. Note that when the remaining oil of our car is 1 4, it is most appropriate to refuel at this time. This not only avoids frequent refueling, but also reasonably protects our engine, so that our car will not be useful and thrown on the road if it is dry.

This not only saves fuel and maintains the car, but also does not increase our fuel consumption.

Of course, we also need some skill when refueling. Some people are at home, and sometimes they directly say "add 200" to the gas worker, and some people directly say "fill up". So which way is the most suitable?

Experts say that when we usually refuel, adding 2 to 3 oil is the best amount, which is not only particularly fuel-efficient, but also special for car maintenance. Speaking of which, I believe everyone understands something, so don't be smart enough to join when you usually refuel, or add 200 directly, but be sure to refuel directly with 2 3. Of course, refueling at 1 4 in our tanks is the most suitable.

I will share the difference with you every day.
