Revealed: 10 ways to improve your car’s fuel efficiency

Insurance experts A-Plan Insurance take you through 10 top tips. 

1. Watch your speed to reduce fuel consumption

The RAC says driving at 45 – 50mph is the most efficient speed for fuel consumption, not the ‘56mph myth’ many have been adhering to. 

According to the Department for Transport, driving at 70mph uses up to 9% more fuel than at 60mph and up to 15% more than at 50mph. 80mph can use up to 25% more than at 70mph. Use cruise control for motorway driving if you have it.

2. Watch your gears to reduce fuel consumption

Change up and down multiple gears at a time and change to the highest suitable gear as soon as you can to avoid over-revving. 

The AA advises against coasting, where you engage ‘neutral’ or drive with the clutch held down, deeming it unsafe and unlikely to save you any fuel.

3. Accelerate and brake gently to reduce fuel consumption

Developing a smooth driving technique is a great way to save on fuel. If you’re approaching traffic lights, for example, slow down early so that they may have changed by the time you reach them, meaning you might not need to stop at all. 

Anticipate the road in front of you and ease off the throttle and maintain momentum rather than braking hard and then accelerating again.

4. Remove weight and reduce drag to reduce fuel consumption

The drag from carrying extra weight reduces your cars fuel efficiency, so remove any unnecessary items from the boot, and remove your bike rack or roof rack when you don’t need it. A heavier car needs more fuel to keep it moving.

5. Use aircon less often to reduce fuel consumption

Using aircon can increase fuel consumption by around 10% according to the AA. Opening your windows (or lowering your soft top) is a cheaper option!

6. Maintain your tyres to reduce fuel consumption

Check your tyre pressure at least once a month. Under-inflated tyres burn more fuel. If tyres are 8 pounds under inflated (not an uncommon condition), rolling resistance of the tyres increases by 5 per cent.

7. Regular services will help reduce fuel consumption

Keep everything in tip top efficient condition. Replace oil, air and fuel filters at the recommended intervals.

8. Avoid short trips to reduce fuel consumption

And if you are taking short trips, it’s even more important to switch off that aircon as it will use most of its energy for the initial cool-down.

9. Avoid traffic hotspots to reduce fuel consumption

Idling consumes around 0.6 litres of fuel per hour. A vehicle with a stop/start engine is recommended if you are frequently stuck in jams. Google Maps can be a fuel saver by pointing out routes that are congested and offering alternatives that keep you moving.

10. Upgrade your car to reduce fuel consumption

While we’re focusing on money saving and realise a new car isn’t an option for many right now, some may be in a position to update their vehicle. With the rising cost of fuel, investing in a newer car (not necessarily brand new!) will immediately save you a fortune in fuel – as well as reducing your road tax. 

Parkers rates the Renault Clio E-Tech as the UK’s most economical non-plug-in, averaging 73.8mpg, while the Peugeot 208 averages 71.4pmg. If you’re looking for a larger vehicle, the SEAT C3 averages 70.6mpg, and the Skoda Octavia, named as ‘best family car’ averages 65.7pmg!

If you are on the market for a replacement vehicle, and not ready to go electric, diesel generally provides better fuel economy than their petrol equivalents.


Although we can’t help you to reduce the cost of fuel, reducing your mileage could also reduce your car insurance premiums.
