The definition of consumption in practice

The fuel consumption of the vehicle can be checked between the two stations. Many experts believe this is the most correct decision. For this you need to wait until the gage shows that the fuel is running out. Simply put, your dashboard will flash a light near the fuel gauge.

Then you need to stop at a gas station and ask the attendant to fill it up. The signal that the tank was filled with fuel, will provide a refueling nozzle which automatically shuts down, ceasing to deliver fuel. Make a note of how many liters it was able to fill. Additionally fix the speedometer before leaving from the gas station.

Then calmly go until the flashing fuel gauge. This would mean that you went the whole supply poured into the tank at the last gas station. Once this is found, stop and equip your calculator, rummage in memory or records in order to know how many kilometers were crossed what of the current indicator of the speedometer, you need to subtract recorded at the gas station. Then make the calculation. The number of kilometers, divide by 100, then the quantity of fuel filled, divide by the result. This will be the fuel consumption of the vehicle per 100 km.

For example, suppose that during refueling in the vehicle was filled with 48 l of petrol and the indicator on the speedometer was 12800 km. After I started to flash the fuel gauge, the speedometer showed 13420 km from these data, we can calculate the fuel consumption. To do this, calculate the mileage on 48 l of petrol. It is equal 13420-12800=620 km. Divide that number by 100, you get a 6.2. The amount of fuel divide by the result 48/6,2≈7,74 L. that's how much the car consumes per 100 km. To know the amount of fuel required for a planned trip, multiply this figure by the length of the path, hundreds of miles away. For example, if you need to overcome the route length of 850 km, the amount of fuel that will need to be 8,5•7,74≈65,8 L. Multiplying by the current price of gasoline it is possible to learn the amount that will be needed in order to reach the destination. In order to return, it must be doubled.

The disadvantages of this method include its duration, as to leave almost a full tank of fuel will take time. In addition, this flow gives us an opportunity to evaluate the fuel consumption in mixed mode. However, with the quality of local roads, this mode is often the most marketable.

Calculation of fuel consumption using a calculator

To determine the fuel consumption of a vehicle with the help of specialized calculators that are built into the sites. For this special form enter the starting and ending point of the trip, as well as the nodal point of the route. After the introduction of the brand of car calculator to approximately calculate the fuel consumption per 100 km, the total fuel and the cost of the trip.

The disadvantage of these programs is that they do not take into account the real condition of the car. Therefore, the result often gives too low a flow rate, and such calculators are preferably treated with a healthy dose of criticism. Moreover, they show an approximate order of costs for the trip is quite accurate.

An even easier method is to get vehicle data on fuel consumption, with the router to determine the path length with precision up to hundreds of kilometers and multiply these values. The result will be the approximate fuel consumption for the whole trip. The problem is that the passport and the real data in practice are very different, which is often associated with the condition of the engine and fuel quality.
