How to Save Money on Petrol Without Driving Less

Introduction

With petrol prices still a major cost for UK drivers, many of us are wondering how to cut our fuel bills without giving up our cars. Whether you're commuting, running errands or heading on a road trip, there are easy ways to reduce how much you spend on fuel — without driving any less.

Here’s how to get more miles for your money and save on petrol every week.

1. Drive Smoothly

Harsh braking, fast acceleration and racing between traffic lights guzzle fuel. Try:

• Gentle acceleration

• Early gear changes

• Anticipating traffic flow

🚗 You could save up to 15% on fuel just by driving more smoothly.

2. Keep Tyres Properly Inflated

Under-inflated tyres increase rolling resistance and burn more fuel. Check your tyre pressure at least once a month — or every long journey.

🛞 Tip: Use the pressure recommended in your vehicle’s handbook or sticker in the door frame.

3. Use Supermarket Fuel Loyalty Schemes

Supermarkets often have the cheapest petrol and run fuel promotions:

• Tesco Clubcard points

• Sainsbury’s Nectar offers

• Morrisons More Card discounts

⛽ Stack points and save at the pump or on future shops.

4. Avoid Idling

Leaving your engine running while parked wastes fuel. If you're stopping for more than a minute (like at level crossings or school pick-up), turn off the engine.

💡 Modern engines use less fuel restarting than idling for long periods.

5. Use Fuel Price Comparison Apps

Apps like PetrolPrices or Waze can help you find the cheapest petrol near you — often saving 5–10p per litre just by going to a different forecourt.

📱 Over a full tank, that could be £3–£6 saved each time.

6. Lighten Your Load

Carrying unnecessary weight makes your engine work harder. Clear out heavy items and remove roof racks or boxes when not in use to reduce drag and fuel consumption.

🎒 Every extra 50kg can cut fuel efficiency by around 1–2%.

7. Don’t Fill Your Tank All the Way (Every Time)

A full tank adds extra weight, especially in larger vehicles. If you’re only making short local trips, consider half-filling your tank to reduce load.

⛽ Only practical if you drive near affordable fuel stations.

8. Use Cruise Control (When Safe)

On motorways and flat roads, cruise control helps maintain a consistent speed — reducing fuel use compared to fluctuating acceleration.

⚠️ Avoid on hilly terrain as it can use more fuel uphill.

9. Plan More Efficient Routes

Avoid traffic-heavy times and plan routes with fewer stops. Google Maps and Waze both offer eco-friendly routing to help cut fuel use.

🧭 Fewer stop-starts = better fuel economy.

10. Service Your Car Regularly

A well-maintained engine runs more efficiently. Dirty air filters, worn spark plugs, or old oil can reduce MPG.

🛠️ Follow your vehicle's service schedule — it’ll pay off in fuel savings.

Final Thoughts

Fuel is one of the biggest ongoing expenses for many UK households — but there are plenty of ways to cut costs without changing your lifestyle. A few simple adjustments can make a big difference at the pump and keep more money in your pocket.
