Fuel efficiency: A brief overview

Fuel efficiency is an important issue when it comes to owning a car in the UK. With high petrol and diesel prices, it’s essential to make sure you’re getting the best possible value from every litre of fuel you buy.

Fortunately, there are plenty of ways to improve your vehicle’s fuel efficiency, saving money and reducing your carbon footprint.

Tips for improving fuel efficiency

  • Keep your car well-maintained and serviced regularly.
  • Check tyre pressure to make sure it’s at the recommended level for your vehicle.
  • Avoid excessive idling and drive at a steady speed without accelerating or braking suddenly.
  • Avoid opening windows when driving at high speeds to reduce drag.
  • Try not to carry unnecessary items in the boot as they add weight and reduce fuel efficiency.
  • Consider replacing an old car with a more efficient model that can save you money in fuel costs over time.

How to calculate your vehicle’s fuel efficiency (MPG)

To work out your vehicle’s fuel efficiency, you’ll need to determine how many miles per gallon it gets. This can be calculated using our MPG calculator.

All you need to do is enter the amount of petrol or diesel used, along with your vehicle’s odometer readings and the calculator will work out your MPG.

What affects fuel efficiency?

There are several factors that can influence how much fuel your car uses. These include the car’s age, its maintenance and service history, driving style, the type of roads you’re driving on, tyre pressure and engine size. Keeping your car well-maintained and serviced regularly will also help to maximise its fuel efficiency.

How to save money on fuel

Saving money on fuel can be a challenge but it is possible with some simple tips and tricks. Here are 3 simple things you can do:

  1. Consolidate errands – Plan out your trips so that you can run all of your errands in one go, rather than making multiple trips. This will save you time and money as you won’t have to waste fuel travelling the same road twice.
  2. Stick to speed limits – The higher the speed, the more fuel your car will use, so it pays to stick to the speed limit.
  3. Shop around for petrol stations – Different petrol stations may offer different prices for the same brand of fuel, so do some research ahead of time and make sure you fill up at the cheapest station available.

Fuel efficiency and the environment

The more fuel-efficient your car is, the less CO2 it will emit into the atmosphere. As well as reducing your carbon footprint and saving money on petrol or diesel costs, choosing a fuel-efficient vehicle can help to reduce air pollution and protect the planet.

Remember, improving your vehicle’s fuel efficiency isn’t always just about buying a newer, more efficient car. With the right maintenance and driving techniques, you can make your existing car much more fuel-efficient and save money in the long run.
