5 Expert Tips to Help You Save Fuel and Cut Petrol Costs

With fuel prices remaining high and economic pressures affecting households across the UK, many drivers are looking for practical ways to make every litre go further. Whether you’re behind the wheel daily or only drive occasionally, improving your vehicle’s fuel efficiency can lead to noticeable savings over time.

From adjusting your driving habits to making small changes in how you maintain your car, there are several effective strategies you can use to cut down on petrol costs. In this guide, Motorscan shares five expert-backed tips to help you save fuel and get the most out of every journey.

1. Drive Smoothly and Anticipate the Road Ahead

Erratic driving habits like sudden acceleration, harsh braking, and unnecessary gear changes can significantly increase fuel consumption. A smooth driving style is more economical and less stressful for both you and your car.

Try to anticipate traffic conditions in advance, look well ahead and adjust your speed early. For example, if traffic lights are red up ahead, ease off the accelerator and coast, rather than speeding up only to brake harshly. Using cruise control on motorways, where safe, can also help maintain a consistent speed and reduce fuel use.

2. Keep Tyres Inflated to the Correct Pressure

Tyres that are even slightly under-inflated create more rolling resistance, which means your engine has to work harder and burn more fuel. According to the RAC, driving on under-inflated tyres can reduce fuel efficiency by as much as 10%.

Check tyre pressures at least once a month and before long journeys. You can find the correct pressure settings in your vehicle’s handbook or inside the driver’s door frame. Don’t forget to check the spare tyre too, if you have one.

3. Lighten the Load and Reduce Aerodynamic Drag

Carrying unnecessary weight in your vehicle increases fuel consumption, especially in smaller cars with less powerful engines. Clear out any items you don’t need in the boot or back seats.

Similarly, roof racks, roof boxes, and bike carriers create extra wind resistance. Even when empty, they reduce your vehicle’s aerodynamics and increase drag, particularly at motorway speeds. Removing them when not in use can lead to noticeable fuel savings, up to 20% in some cases, depending on the vehicle and load.

4. Compare Live Fuel Prices Before You Fill Up

One of the simplest ways to save money on petrol is by filling up at the cheapest local station. Prices can vary dramatically between forecourts even within the same town.

Before heading to the pump, visit CheckFuelPrices.co.uk to compare fuel prices at over 4,000 UK petrol stations. The site helps you find the best value nearby, whether you’re after E10, E5, or diesel. Taking a couple of minutes to check before you fill up can lead to consistent savings over time.

5. Combine Journeys and Avoid Short Trips

Cold starts are one of the biggest fuel wasters. Engines run less efficiently when cold, and the catalytic converter takes longer to become effective. Taking several short trips with a cold engine uses far more fuel than a single, longer trip of the same total distance.

Where possible, combine errands and plan your route in advance to avoid backtracking or heavy traffic. Use real-time traffic apps or sat-navs to find the quickest and most efficient routes. Avoiding peak congestion times will also help reduce stop-start driving, which is fuel-intensive.

Saving fuel isn’t just about how you drive, it’s about thinking ahead, maintaining your vehicle, and using the right tools. By adopting these five tips, you can reduce your fuel consumption, save money, and minimise your carbon footprint. To make even smarter decisions at the pump, remember to check live petrol prices before your next refill.
