PacificAuto.com needs to fill up the vehicle with fuel and zero out the mileage or record the information. Use a period of time and then refuel until the gun jumps, divided by the mileage of the two refueling, and then multiplied by one hundred is the real fuel consumption. After that, you can calculate the mileage and gas mileage according to the rules. Hundred kilometers of fuel consumption = the volume of a certain amount of fuel (liters) / the distance that the car can travel with that amount of fuel (kilometers) X 100.

For example: a car consuming A liters of fuel travels N kilometers, then the hundred kilometers of fuel consumption = A?NX100. Bringing in a specific number, if a car consuming 4 liters of fuel can travel 50 kilometers, then the hundred kilometers of fuel consumption for the car = 4 liters/50 kilometers X 100 = 8 liters/100 kilometers, and the fuel consumption for 100 kilometers is 8 liters, which is commonly known as ?8 gas?

If the cumulative amount of fuel purchased is counted from the start of the vehicle and divided by the total mileage traveled, the above formula can be used to obtain a more accurate fuel consumption of 100 kilometers. If there is no such original fuel purchase data, there are many people who put the fuel gauge indication and odometer counting figures into the above formula, which involves the issue of a measuring device, and if you don't pay attention to the accuracy of the measuring device, the result of the calculation will have a relatively large error.
