Petrol Calculator

The petrol calculator below will help you to quickly and accurately work out the cost of petrol for your one-way or return trip anywhere in the UK.

Just input a few basic details into the petrol cost calculator and you’ll get an estimated petrol cost and fuel consumption calculation for your journey.

How to use our Petrol Calculator

Our petrol calculator is super-easy to use. All you need to do is enter these details into the calculator:

I need to drive: Enter the distance you need to drive in this box. For example, if you need to drive 100 miles, just enter figure 100.

Miles or Kilometres: Choose the measurement you require. The calculator is set to miles by default. It’s very important that you choose the correct measurement because this will affect the calculations for the price and the quantity of fuel required.

My car’s MPG: Enter the MPG of your car into this box. If you don’t know your car’s real MPG, you can use our MPG calculator to work this out.

Petrol price (Pence): Enter the price you’re paying per litre of petrol, in pence. For example, 172 or 175.

Round trip required: Choose whether or not you would like the petrol calculator to include a return cost. If you choose yes, this will double the price and fuel quantity automatically.

How to Improve Your Vehicle’s Fuel Efficiency and Save Money on Fuel

With fuel prices constantly on the rise, filling up your tank can feel like a never-ending expense. But the good news is, there are plenty of ways to improve your car’s fuel efficiency and save money on fuel.

By making a few simple changes to your driving habits and keeping your vehicle well-maintained, you can significantly reduce your fuel consumption and keep more cash in your pocket.

1. Maintain Proper Tyre Pressure

Underinflated tyres create more rolling resistance, which means your engine has to work harder and burn more fuel. Check your tyre pressure regularly (at least once a month) and keep it at the recommended level. You’ll find the correct pressure in your vehicle’s owner’s manual or on a sticker inside the driver’s door.

2. Drive Smoothly

Aggressive driving, such as rapid acceleration and hard braking, can increase fuel consumption by up to 40%. Instead, accelerate gently and brake gradually. Smooth driving not only saves fuel but also reduces wear and tear on your car.

3. Avoid Idling

Idling wastes fuel, especially if you’re stuck in traffic or waiting for someone. If you’re going to be stationary for more than a minute, turn off your engine. Modern engines use less fuel to restart than they do while idling.

4. Use Cruise Control

Cruise control helps maintain a constant speed, which improves fuel efficiency on motorways. It prevents unnecessary acceleration and deceleration, especially on long journeys.

5. Reduce Weight

Extra weight in your car forces the engine to work harder, which increases fuel consumption. Remove unnecessary items from your boot or backseat, such as sports gear, tools, or luggage you don’t need.

6. Plan Your Trips

Combine errands into one trip instead of making multiple short journeys. Cold engines use more fuel, so driving longer distances with a warm engine is more efficient.

7. Avoid Roof Racks and Carriers

Roof racks and carriers create wind resistance, which reduces fuel efficiency. If you’re not using them, take them off. When you do need them, pack them efficiently to minimise drag.

8. Keep Your Engine Tuned

A well-maintained engine runs more efficiently. Regularly service your vehicle, including oil changes, air filter replacements, and spark plug checks. A poorly tuned engine can increase fuel consumption by up to 20%.

9. Use the Right Engine Oil

Using the manufacturer-recommended grade of engine oil can improve fuel efficiency by 1-2%. Look for engine oil labeled “energy-conserving” or “fuel-efficient.”

10. Avoid High Speeds

Driving at high speeds significantly increases fuel consumption due to wind resistance. For most cars, fuel efficiency drops rapidly at speeds above 50-60 mph. Stick to the speed limit and save fuel.

11. Use Air Conditioning Wisely

Air conditioning can increase fuel consumption, especially at low speeds. At higher speeds, open windows create drag, so using the AC is more efficient. Use the AC sparingly and consider using the vent setting when possible.

12. Check Your Fuel Cap

A loose, damaged, or missing fuel cap can allow fuel to evaporate. Make sure your fuel cap is tight and in good condition to prevent fuel loss.

13. Avoid Rush Hour

Stop-and-go traffic is a major fuel waster. If possible, adjust your schedule to avoid driving during peak traffic hours. This will help you maintain a steady speed and save fuel.

14. Use Overdrive Gears

If your car has an overdrive gear, use it. Overdrive reduces engine speed, which improves fuel efficiency on motorways.

15. Keep Your Fuel System Clean

Dirty fuel injectors or a clogged fuel filter can reduce fuel efficiency. Use a fuel system cleaner periodically to keep your fuel system running smoothly.

16. Avoid Unnecessary Accessories

Accessories like roof-mounted cargo boxes, bike racks, and even decorative spoilers can increase wind resistance and reduce fuel efficiency. Remove them when not in use.

17. Monitor Your Fuel Consumption

Keep track of your fuel consumption to identify any sudden drops in efficiency. This can help you catch issues like underinflated tyres or a malfunctioning engine early.

18. Use the Correct Fuel

Using premium fuel when your car doesn’t require it is a waste of money. Check your owner’s manual to see what type of fuel is recommended for your vehicle.

19. Drive in the Right Gear

If you drive a manual car, shift up to a higher gear as soon as possible without straining the engine. Driving in a lower gear than necessary increases fuel consumption.

20. Consider a Fuel-Efficient Vehicle

If you’re in the market for a new car, consider a fuel-efficient model. Hybrids, electric vehicles, and cars with smaller engines can save you a significant amount of money on fuel in the long run.

Bonus Tips

• Carpool or Use Public Transport: Sharing rides or using public transportation can drastically reduce your fuel expenses.
• Walk or Cycle: For short trips, consider walking or cycling instead of driving. It’s not only fuel-efficient but also good for your health.
• Use Apps to Find Cheap Fuel: Apps like PetrolPrices can help you find the cheapest fuel stations in your area.

 

Improving your car’s fuel efficiency doesn’t require drastic changes. By adopting these simple habits and making small adjustments, you can save a significant amount of money on fuel.

Not only will you reduce your expenses, but you’ll also contribute to a cleaner environment by lowering your carbon footprint.
