8 Practical Ways to Improve Your Vehicle’s Fuel Efficiency

Nobody wants to spend more than they need to on fuel, especially with prices as high as they have been.

Whilst making the switch to a hybrid or electric car is hands-down the best way to “drive green” – this simply isn’t a practical solution for everyone.

The good news? There are plenty of practical and effective steps you can take to improve your vehicle’s fuel efficiency.

At Caledonian Couriers, we spend a lot of time on the road and it’s become a bit of a competition for us to see how much we can improve our fuel efficiency. Here are some of our favourite top tips to drive greener.

1. Change Out Your Air Filter

When was the last time you swapped out your air filter? If it’s been more than a year, there’s a good chance your current filter is clogged. A clogged air filter can reduce air circulation to your engine, which will cause your engine to work harder than it needs to, reducing your fuel economy in the process.

You can swap out your own air filter pretty easily or have it done by a trusted mechanic.

2. Don’t Forget the Oil Change

When you change the oil in your car, you’re making sure all those tiny moving parts of your engine are well lubricated. This, in turn, helps your engine run more efficiently, which can lead to better fuel efficiency.

Check your vehicle owner’s manual to find out exactly how long you should go between oil changes and make sure you’re following those recommendations.

3. Schedule a General Tune-Up

If you have a trusted mechanic or garage in your area, you might also consider scheduling a general tune-up for your vehicle. Not only are these great for keeping your car running its best and potentially avoiding costly repairs, but tune-ups can also help your car run more efficiently all around.

4. Get Rid of Unnecessary Clutter

Did you know that added weight in your car can drastically reduce your fuel economy? This is especially true in cars with smaller engines, which will have to work harder to get your vehicle up-to-speed when there’s more weight in the cabin.

Take some time to clear out any unnecessary clutter (like that bag of sports gear or those extra tools) from your car and you may be surprised at what a difference this can make in your fuel economy.

5. Check Your Tyre Pressure

When was the last time you checked your tyre pressure to ensure that your car’s tyres were properly inflated? Ideally, you should be doing this at least once a month. Having your tyres inflated to the proper pressure not only helps ensure even wear and tear, but it will optimise your car’s fuel efficiency as well.

You can usually check your tyre pressure at most fuel station for 50p and topping up the air only takes a few seconds of your time.

6. Stop Idling Your Engine

Do you have a habit of letting your car’s engine idle while you’re not actually driving? If so, think of it this way: any time your car’s engine is idling, you’re getting exactly zero miles per gallon. Even a few minutes of idling, then, can drastically reduce your fuel economy.

Practice smart driving by making an active effort to avoid engine idling; even if you’re sitting in stopped traffic for more than 60 seconds, it’s generally more fuel efficient to shut off your engine altogether.

7. Use Cruise Control

Driving at inconsistent speeds can also reduce your fuel economy, so utilise your car’s cruise control when appropriate. This can save you a substantial amount of fuel when used at motorway speeds and is also a great way to make sure you’re not speeding without realising it!

8. Know When to Shut Off the AC

Running your car’s AC can also reduce fuel economy so use it wisely. Generally, it is more efficient to run your car’s AC at highway speeds than it is at stop-and-go city speeds, so consider turning off the AC and rolling your windows down when you’re just driving around town.
