There are several ways to calculate the fuel consumption of a car. Let us dwell on the most frequently used in practical activities.
To do this, fill a full tank with gasoline, take a speedometer (for example, 773220) and drive a few kilometers around the city, along the highway, trying to go along those routes where you have to work constantly in the future.
Then refill the full tank of fuel and read the speedometer (for example, 773550). The result was a mileage of 330 km. From the check from the second gas station you can find out how much gas it took to top up to a full tank. For example, 30 liters.
We compose the proportions: 30 liters of gasoline were required for 330 km, and x liters per 100 km of run. 100 * 30/330 = 9 liters
Fill a full tank of fuel and drive 100 km. Then return to the gas station and top up the tank. How many liters will be needed for this, such is the fuel consumption per 100 km.
You can use the data of the technical passport, depending on the engine size, there is a standard fuel consumption.
But the methods for calculating fuel consumption with a 100% guarantee simply do not exist. Yes, and take into account the correction factors in real life is also necessary:
1. In the winter period of time, from October to March, depending on the region, there is a surcharge of 10%. The Ministry of Transport issues an order, and the head of the enterprise issues an order to increase the rate of gasoline consumption.
2. In cities with a population of more than 3 million. people apply a coefficient of up to 25%. This must also be indicated in an order or order of local authorities.
3. Depending on how many years the vehicle has been operating, an additional conversion factor is used, but not more than 5%. If the machine has been working for more than 5 years, you can take advantage of this extra charge.
Thus, fuel consumption is the amount of gasoline that is spent per 100 kilometers. In everyday life, taking into account the warming up of a car on frosty days, frequent stops in front of a traffic light, driving empty and with large loads for freight transport, bus mileage at rush hour and driving with low occupancy.
Consumption rates at the enterprise are set taking into account the vehicle data sheet from the manufacturer. And how to calculate fuel consumption if special equipment is installed on the car? Then the standards are approved at the enterprise independently, but taking into account the methodological recommendations for special equipment.
Actual accounting and write-off of fuel and lubricants occurs in accounting based on the provided waybills. Therefore know how to calculate flow fuel, should the driver. He fills the waybill, speedometer, mileage and gas mileage for trips. And most importantly, it indicates the remainder of the gas in the tank before departure, the amount of fuel refueled and the remainder at the end of the day.
In order to prevent unnecessarily excessive consumption of fuel, the driver must know how to determine fuel consumption for your car. Monitor its technical condition, change oil and rubber on wheels in time. Indeed, when an overrun is detected due to the driver’s fault, the write-off is at the expense of the employee himself, by deducting the cost of the excess from his salary.
If the financial condition of the driver is unsatisfactory, then the employer can exempt him from paying off the overspending amount and write off it at the expense of other expenses, but the accountant will no longer be able to take this amount for deductions, calculating taxes from the company's profit.
Therefore, knowing how to calculate fuel consumption is important for both the employee and the employer. And we must remember that the consumption also depends on the quality of the fuel, on the filters, the need for warming up the engine, on the track itself and traffic congestion on the roads.
