How to treat the cruising range of oil vehicles?

It is often seen that some drivers adjust the instrument interface to the mileage page, so that they can know how far their car can run in real time, which is easy to understand. Seeing that the voyage was not enough, they went to refuel. In fact, when we refuel, the indicator of the oil gauge pointer is more accurate than the range. There is a float in the oil tank, and a sliding resistor is connected to the float, which transmits the signal to the instrument for display, which is very accurate. The computer calculates mileage according to a series of factors such as current fuel consumption, recent fuel consumption, current driving speed, road conditions and load. Affected by external factors such as road conditions and changes greatly, it is only a rough value. So mileage can only be used as a reference. Don't wait a few kilometers before refueling. It is easy to run out of fuel before reaching the gas station. The latest refueling time is when the fuel warning light is on. You need to refuel immediately after driving. The range of driving road conditions is basically changing all the time, and sometimes it changes greatly. Just now, the distance is 100 km. After running for a while, it became 120 km. The longer you run, the higher the distance. This is determined by the road conditions. It may become smaller in an instant and then suddenly become 80 kilometers. It's possible. So the mileage is not accurate. Good road conditions or similar road conditions. You can refer to, for example, the ever-changing road conditions, sometimes traffic jams, sometimes clear, and so on. , the reference is of little significance. It depends on the fuel gauge. When we refuel depends on the fuel gauge. There are many gas stations in this city, so it's not too late to wait until the indicator light of the oil meter is on. If you drive in a place with few gas stations, how far do you need to drive according to the actual situation? How much oil is there in the tank? If the traffic jam is serious or unimpeded, it is necessary to comprehensively calculate and decide when to refuel. Some people say that refueling will only damage the gasoline pump when the indicator light is on. That was not the case. The cooling of the pump depends not on the surrounding gasoline, but on the oil it sucks in. As long as the engine oil can be inhaled, it will not produce high temperature and damage the gasoline pump.
