How to calculate fuel consumption

There are several ways to calculate the fuel consumption of a car. Let us dwell on the most frequently used in practical activity.

To do this, you need to fill the tank with gasoline, take the speedometer readings (for example, 773220) and drive a few kilometers around the city, along the road, trying to drive on those routes where you will constantly work in the future.

Then again refill the full tank of fuel and read the speedometer readings (for example, 773550). The mileage was 330 km. By check with the second refueling you can find out how much gasoline it took to add to the state of the full tank. For example, 30 liters.

We form proportions: for 330 km it took 30 liters of gasoline, and for 100 km of run it is necessary - x liters. 100 * 30/330 = 9 liters

Fill a full tank of fuel and roll 100 km. Then go back to the gas station and top up the tank. How many liters will be needed for this, such is fuel consumption per 100 km.

You can use the data of the technical passport, depending on the volume of the engine there is a standard fuel consumption.

But the methodology, how to calculate the fuel consumption with a guarantee of 100%, simply does not exist. Yes, and take into account the correction factors in real life, too, is necessary:

1. In the winter period, from October to March, depending on the region, there is a 10% surcharge. The Ministry of Transport issues an order, and the head of the enterprise - an appropriate order to increase the rate of consumption of gasoline.

2. In cities with a population of more than 3 million. People apply the coefficient to 25%. This must also be indicated in the order or the order of the local authorities.

3. Depending on how many years the motor vehicle serves, an additional recalculation factor is used, but not more than 5%. If the machine works more than 5 years, you can use this premium.

Thus, the fuel consumption is the volume of gasoline, which is spent for 100 km of run. In everyday life take into account the warm-up of the car in frosty days, frequent stops in front of the traffic lights, empty vehicles and with large loads for freight transport, bus rush hour and low-occupancy driving.

The norms of consumption at the enterprise are set taking into account the vehicle's technical certificate from the manufacturer. And how to calculate the fuel consumption, if the car is equipped with special equipment? 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 takes place in the accounting department on the basis of the provided travel sheets. So know how to calculate the flow Fuel, should and the driver. He fills out the waybill, speedometer readings, mileage and fuel consumption for trips. And most importantly, it indicates the rest of the gasoline in the tank before departure, the amount of fuel and the balance at the end of the day.

To prevent unreasonable over-expenditure of fuel, the driver must know how to determine fuel consumption For your car. To monitor its technical condition, change the oil in time, rubber on wheels. After all, if there is an overspending due to the driver's fault, the write-off is at the expense of the employee himself, by keeping the surplus value from his wages.

If the financial condition of the driver is unsatisfactory, the employer can release him from paying off the amount of overspending and write off at the expense of other expenses, but the accountant can no longer take this amount for deductions, calculating taxes from the profit of the enterprise.

Therefore, knowing how to calculate fuel consumption is important for both the employee and the employer. And we must remember that the consumption depends on the quality of the fuel, from the filters, the need for warming up the engine, from the road itself and traffic congestion in the transport.
