How does the fuel cost calculator work?
After entering some vehicle-related information, you will immediately receive the travel costs as a result. Whether for your personal cost overview or for a proportionate cost allocation to passengers, with the fuel cost calculator you will quickly find out. Note, however, that wear and tear are not included. The following data are required:
- Petrol price in euros per liter
- Consumption in liters per 100 km
- Distance in km
Calculate fuel consumption, that’s how it works
For the above calculation you are probably missing the consumption in liters per 100 km. Of course, you can use the consumption per 100 km according to the manufacturer. However, it is more precise to determine your own consumption per 100 kilometers. This is how you do it:
- Set your daily kilometers to zero after the next refueling.
- After the next refueling, note the number of liters you have just refueled.
- Divide the liters of fuel you have filled by the displayed daily mileage.
- Multiply by 100. You already have the liters consumed per 100 km.
You fill up, according to the display, 27 liters.
Daily kilometers show 400 km.
(27 liters / 400 kilometers) * 100 = 6.75 l / 100 km
Annotation: It is important that you always fill up the tank, because this is the only way to get a guideline for the amount of fuel used. Note that the proportion of long and short journeys or city trips usually varies. If you want to know exactly, the consumption can only be calculated exactly if you carry out the calculation several times and averages it.
How can you reduce fuel consumption?
Apply less gas
Never fully depress the accelerator. Most cars can be set in motion without accelerating too much. Most fuel is consumed when starting off, as the weight of the vehicle first has to be set in motion. In addition, in higher gears and at higher speeds, it often doesn’t make much difference whether you press the accelerator all the way down or not: the speed remains the same, but more fuel is used when you step down.
After pulling away, quickly shift into second gear. In general, the earlier you change gear and the lower the speed range, the less gasoline your vehicle uses.
Drive with foresight
If you can see an obstacle, release the gas early. You can save a lot of fuel by trying to keep your car moving and starting from a standstill as little as possible.
Short engine running times
Contrary to the rumors that switching off and starting the engine would use up additional fuel, it is always worthwhile to switch off the engine for a short while if you have to wait a short time. Likewise, it makes little sense to let the engine warm up before starting. Here too, fuel is used unnecessarily.
Regular maintenance and care
Do you already have a fuel-efficient vehicle? To keep it that way, it is advisable to carry out the necessary inspections on a regular basis. Anyone who does not change the oil or take care of the replacement of technical wear parts can assume that fuel consumption will gradually increase.
Get rid of ballast
It is also worth leaving unnecessary luggage or other unnecessary ballast at home. The lighter the vehicle, the lower the consumption.
Check tire pressure
Not only the weight is decisive, the rolling resistance of the tires can also be reduced somewhat with the correct tire pressure. A tire pressure up to 0.2 bar higher than specified by the manufacturer is usually not a problem and, due to the slightly smaller contact surface of the tires, leads to lower rolling resistance and thus less consumption.
Switch off unnecessary electronics
By switching off devices that are not currently required – especially the air conditioning – a few liters of petrol or diesel can be saved per 100 kilometers. The same applies to open windows when driving: On the one hand, the air resistance is increased enormously, on the other hand, the performance of the air conditioning system fizzles out completely senseless, which also results in higher costs, since the air conditioning system also draws its power from the running engine.
