How to refuel a car can save money?

Gasoline is charged by volume, not by weight. According to the principle of heat expansion and cold contraction, when the temperature is low in the morning and at night, the volume of gasoline is smaller, and more oil can be added at the same cost. However, it should be noted that it is not worthwhile to go out to the gas station or take a long detour to refuel in order to refuel in the morning and evening. After all, the gap that affects the turnover here is not as big as the legend, and every little makes a mickle to save some money.

2. according to the quantity.

Listen to the staff at the gas station and say that it is more cost-effective to add as much liters as possible when selecting oil. Many people are used to saying how much oil to add when refueling, but after rounding off, you will find that the volume is quite different, and you will lose money invisibly.

3. Don't refuel when you see the tanker.

If you find a tanker parked at the gas station, you don't have to refuel, but it is recommended to find another gas station to refuel. Because after changing the oil, the impurities at the bottom of the tank will surge for many years. If these impurities enter the engine cylinder, it is likely to affect the car.

View:

1, the oil pump is oil-soaked, so no matter how you refuel, you must first ensure that the oil can cover the oil pump. Otherwise, only half of the oil pump is immersed in the oil, which will cause the oil pump to heat up.

2. Driving at low oil level for a long time will lead to inaccurate oil level display, which will lead to the inconsistency between the actual oil level and the displayed oil level.

3, everything has a shelf life-gasoline is no exception, if you run less, when you fill the tank with oil and can't use it for a long time, the combustion performance of gasoline will decline and fuel consumption will increase.

4. Gasoline has weight. Reiz's 70-liter fuel tank is equivalent to 56 kilograms. If it's a short trip, it's best not to run with a fuel tank of nearly 120 kg-equivalent to pulling one more person-which costs oil.

5. It is best to add fuel according to the amount of money, such as 100 yuan, 150 yuan, etc. Too lazy to change, the oil gun automatically cuts off the oil.
