Fuel Needed (Litres)


Fuel Cost (Estimated)

If you’re not sure about your car’s fuel efficiency, our MPG calculator can help you figure out your exact miles per gallon figure!

How to use our fuel cost calculator

Our fuel cost calculator is extremely easy to use, just use the input box to enter the price you’re paying per litre of fuel, your vehicle’s MPG (miles per gallon) figure, and the distance you intend to drive.

What does MPG mean?

In a nutshell, MPG means how many miles a car can go for every gallon of fuel. MPG is usually given as a number, and it can be used to compare the fuel efficiency of different vehicles.

The higher the MPG rating, the more efficient a car is, so choosing a vehicle with a high MPG can help you save money on fuel over time.

How our fuel cost calculator works

Our calculator uses a very simple formula to determine how much you will have to pay at the pumps for your journey. We use the formula: (cost per litre x distance) ÷ vehicle MPG x 4.546.

Whether you’re going on a weekend getaway or driving up and down the country for work, this tool can help you to budget better by letting you know exactly how much you have to pay at the pumps.

How to improve your vehicle’s fuel efficiency and save money on fuel

With fuel prices on the rise, it is becoming increasingly important to find ways to improve your vehicle’s fuel efficiency.

Whether you have a car or van, there are several small adjustments that you can make that will help to reduce your fuel usage and save you money over time.

1. Check your tyre pressure regularly

Having the right tire pressure is essential for getting the most out of your fuel economy.

Underinflated tires cause more drag and decrease how efficiently your car runs. Make sure to check your tire pressure regularly and top them up as needed.

2. Reduce unnecessary weight in your car

It may not seem like much, but those extra few pounds can add up quickly when it comes to reducing your mileage.

Remove any unnecessary items from the boot of your car, such as sports equipment or heavy tools that you don’t use often. Every little bit helps.

3. Change your oil regularly

When oil gets too dirty, it can reduce engine performance and lead to decreased fuel efficiency. It is recommended that you get an oil change every 3-5 months (depending on the type of oil used) so that your engine stays clean and operates at its optimum level of performance.

4. Use cruise control whenever possible

Cruise control helps maintain consistent speeds which translates into improved mileage since you don’t have sudden starts and stops or fluctuating speeds while driving.

So if you are going on a long drive or even to another town, cruise control can be a great way to save some money on fuel.

5. Drive at steady speeds

Driving at steady speeds helps conserve fuel because when you accelerate quickly it uses up more fuel than when acceleration occurs slowly over time. Try driving at a steady speed whenever possible in order to maximize fuel efficiency.

6. Take care of your engine

Taking care of your engine is one of the best ways to ensure maximum fuel efficiency for your vehicle. Change air filters regularly and make sure all fluids are topped off so that it runs smoothly and efficiently.

7. Avoid idling

Idling your vehicle for extended periods of time wastes a lot of fuel and can significantly reduce fuel efficiency. Whenever possible, try to turn off the engine when you’re stopped instead of letting it idle.

8 . Avoid high speeds

Driving at higher speeds can decrease your fuel efficiency significantly. Whenever possible, try to keep your speed below the posted speed limit in order to maximize fuel efficiency.

9. Use eco mode

Most modern cars come with an eco mode, which you can use to help reduce fuel consumption and get better mileage.

This mode helps reduce engine power and alters your transmission shift points in order to conserve fuel.

10. Drive smarter

Last but not least, smart driving is the best way to reduce fuel usage and save money in the long run.

Smart driving techniques include accelerating slowly, avoiding sudden braking and idling, using cruise control, and following the speed limit.

By driving more efficiently you can reduce your overall fuel costs while also being kinder to the environment.
