Before a long trip, you need to calculate the finances for its successful implementation. To do this, you need to carefully assess the condition of the car, as well as find out the fuel consumption for a long trip. If this is not done, you can face the unpleasant prospect of a monetary deficit, depriving yourself of elementary comfort.
Determination of consumption in practice
The fuel consumption of a vehicle can be checked between two fillings. Many experts consider this to be the most correct solution. To do this, you need to wait until the sensor shows that the fuel is running out. Simply put, the light near the fuel gauge will not blink on the dashboard.
Immediately you need to stop by the gas station and ask the tanker to fill the full tank. The signal that the tank is full of fuel will be given by the refueling nozzle, which will automatically shut off when no more fuel is supplied. Remember or write down how many liters you managed to fill. Additionally, record the speedometer readings before leaving the gas station.
After that, drive quietly until the fuel gauge flashes again. This will mean that you have left all the stock that was filled in the tank at the last gas station. As soon as this is found out, stop and arm yourself with a calculator, rummage through your memory or your own records in order to find out how many kilometers have been traveled for what from the current speedometer indicator, you need to subtract the one recorded at the gas station. After that, make the calculation. Divide the number of kilometers traveled by 100, then divide the amount of fuel poured by the result. This will be the consumption of the car per 100 km.
For example, suppose that during refueling, 48 liters of gasoline were poured into the car, and the indicator on the speedometer was 12,800 km. After the fuel gauge started flashing, the speedometer showed 13,420 km. Based on this data, fuel consumption can be calculated. To do this, calculate the mileage for 48 liters of gasoline. It is equal to 13420-12800 = 620 km. Divide this number by 100, you get 6, 2. Divide the amount of fuel by the resulting result 48/6, 2≈7, 74 liters. This is exactly how much the car consumes per 100 km of track. To find out the amount of fuel required for a planned trip, multiply this indicator by the length of the path, in hundreds of kilometers. For example, if you need to cover a route with a length of 850 km, then the amount of fuel that you need will be 8, 5 • 7, 74-65, 8 liters. By multiplying by the current price of gasoline, you can find out the amount that will be needed to get to your destination. In order to return, it needs to be doubled.
The disadvantages of this technique can be attributed to its duration, since it will take time to drive out an almost full tank of fuel. In addition, this consumption most often makes it possible to estimate the fuel consumption in mixed mode. True, with the quality of domestic roads, this mode is often the most popular.
Calculating fuel consumption using a calculator
You can determine the fuel consumption of a car using specialized calculators that are built into the sites. To do this, the starting and ending points of the journey, as well as the nodal points of the route, are entered in a special form. After entering the car brand, the calculator will approximately calculate the fuel consumption per 100 km, the total amount of 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 an indicator of consumption, and it is desirable to treat such calculators with a healthy dose of criticism. However, they show the approximate order of travel expenses fairly accurately.
An even simpler method is to take the vehicle's passport data on fuel consumption, use a router to determine the path length with an accuracy of hundreds of kilometers and multiply these values. The result will be the estimated fuel consumption for the entire trip. The problem is that the passport and real data in practice are very different, which is most often associated with the condition of the engine and the quality of the fuel.
