What's the difference between filling a car with oil and not filling it with oil?

The amount of fuel to refuel a car is determined by the solar terms. Let's just say. It's cold in spring and autumn and winter, so it's better to fill it up with gas. At that time, neither gasoline nor diesel oil would expand in the fuel tank. According to the percentage, it is best to refuel to 90%. In summer, due to the hot weather, any liquid object will expand with heat and contract with cold. So it's best not to add too much 70%-80%, and try to refuel. Of course, it is the same to go far away. It's no problem to add a little more. It's better to add a little more.

Fill it up with gasoline. It's good. If the car needs gas, it can reduce unnecessary troubles and frequent trips to gas stations. Driving to the gas station also requires a lot of oil. Don't wait for the tank alarm light to come on before refueling. If the amount of oil is too small, the oil pump cannot be saturated with oil, which will affect the heat dissipation to some extent. If the heat dissipation is not timely, the service life of the oil pump will be shortened. When the refueling does not increase to the nominal height, the bleeder valve will always open; When the refueling increases to the nominal height, the valve will close and the gas will not be discharged; When the oil level rises, the gun will jump; When some gas comes out, we can add some more oil, so topping up usually refers to jumping gun.

If the car's fuel tank is in a "semi-oil-deficient" state for a long time, it will also cause harm to the car, because the car is often in a low-oil state, and the oil pump will often be evacuated when encountering bumpy roads. Therefore, the DC engine is always overheated and overloaded, which will shorten the service life of the gasoline pump. It costs hundreds of dollars for an oil pump to break down, not to mention the loss of the vehicle when it breaks down on the road. If it is a short trip, it is recommended to add half a box, which can reduce the load by about 20 kilograms and save fuel. If it is a long distance, it is recommended to fill it up. Don't fill it too full every time, remember to fill it slowly when it is almost full. Overfilling is easy to cause gasoline to enter the pipeline of activated carbon tank system. When this liquid fuel enters the canister, it will not only do harm to the canister itself, but also cause the spark plug to "submerge" along the pipeline, resulting in serious consequences of stopping after refueling.

Attention to vehicle refueling: 1. Fix the refueling point as much as possible. 2. It is best to refuel in the morning or evening to avoid the midday sun. Try to refuel in litres, not in litres. 4. If you want to run a long distance, the more fresh engine oil, the stronger the sense of acceleration when driving at high speed. 5. When driving in urban areas, please fill up half or two-thirds of the fuel tank (increase or decrease according to the location).
