Calculate Fuel Consumption Using Mathematical Formula

Since fuel costs keep changing from time to time, it is best that the motorists know the average fuel consumption of their car. Calculating the fuel consumption of your car can help you save and control fuel expenses in the long run. Motorists can easily calculate fuel consumption if they know the distance covered and the fuel used for that particular commute. Moreover, if you know how to calculate fuel consumption per km, you will also understand when there is a need to refuel the vehicle.

Let’s learn how to calculate fuel consumption of a car.

HOW TO CALCULATE CAR FUEL CONSUMPTION

Here is how to calculate fuel consumption of your car using the simple mathematical formula:

FORMULA TO USE FOR CALCULATING FUEL CONSUMPTION

Some of us may be used to working with the standard of litre/100 km but an easier path to follow is to understand and use the km/litre method. You can carry out a simple calculation using the formulas given under:

Converting km/litre into litre/100 km- divide 100 by km per litre

Imagine your car’s fuel tank is 32 litres that can cover around 656 km before there is a need to refill the fuel.

Now dividing 656 km by 32 litres = 20.5 km/litre. To get how much litres per 100 km is required, divide 100 by this km/litre:

100/20.5 = 4.8 litres/100 km

This shows that a 32-litre tank car uses 4.8 litres of fuel to cover each 100 km.

Converting litre/100 km into km/litre – divide 100 by litres per 100 km

Now let’s take an example to better absorb this formula. For example, the manufacturer’s website/manual says that a specific car uses 6.0 litres of fuel per 100 km (litre/100 km). You can then calculate km per litre by dividing 100 by 6:

100/6 = 16.6 km/litre

This means that the car can drive about 16 km with one litre of fuel.

Once you know how to calculate the fuel efficiency, you can determine easily the fuel your car needs. Besides, you can adopt some useful fuel-efficient driving techniques that may aid to a certain extent in saving fuel expenses.

DOES THE TERRAIN PLAY ANY ROLE IN AVERAGE FUEL CONSUMPTION?

Yes, it certainly does. The terrain on which the vehicle drives have a huge impact on fuel economy. Low-range driving on soft sand, as imaginable, will consume a lot more fuel than driving down the highway at 100km/h. However, there are several other ways to save a vehicle’s fuel.

calculate fuel consumption when driving in desert — Fuel up your vehicle’s tank and drive in a nearby deserted area to calculate fuel consumption before actual plan

To calculate fuel consumption, a tip for a desert trip is to load up your vehicle as you would for the trip and drive it on a sandy area nearby. It is worthwhile to note that some vehicles can be more fuel-efficient in off-road conditions than others.

Therefore, it is important to regularly monitor average fuel consumption throughout your daily trips so you have an upper hand at spotting any sign of irregularities at the earliest.

Make sure you carry safe and non-damaged petrol jerry cans when on a trip to remote areas.

Daily car inspection is a must when travelling to remote areas. This should include thorough examinations of fuel tanks, fuel lines, as well as fuel filters. When carrying jerry cans, ensure that they are secure and haven’t copped any damage.

Hopefully, the method to calculate fuel consumption detailed above will help you to keep a proper check on the refuel needs of your vehicle. However, it is important to note that cars become less fuel-efficient with time. Hence, you might need to replace your vehicle with another fuel-efficient car.
