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 activities.
To do this, pour the full tank of gasoline, removethe speedometer readings (for example, 773220) and drive a few kilometers around the city, along the road, trying to drive along those routes where you will constantly work in the future.
Then refill the full tank of fuel and removethe speedometer reading (for example, 773550). The mileage was 330 km. By check from 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 compose the 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 are needed for this, such is fuel consumption per 100 km.
You can use the data of the technical passport, depending on the size 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 winter, 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 transport serves, an additional factor of recalculation is used, but not more than 5%. If the machine works more than 5 years, you can use this premium.
Thus, fuel consumption isvolume 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 trucks, bus rush hour and low-occupancy driving.
The rates of expenditure in the enterprise are fixed withtaking into account the vehicle data sheet 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 writing 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, he indicates the remainder of 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, to change the oil in time, rubber on the 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 driverunsatisfactory, then the employer can free 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, know how to calculate the flowfuel, it is important for the employee and for the employer. And we must remember that the flow 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.
