A major UK supermarket has vowed to lower the cost of motoring by cutting 4p off the price of petrol and diesel. Asda fuel stations will now sell petrol at 131.96p per litre, whilst a litre of diesel will be slashed to 137.63p in the largest overnightprice drop a supermarket retailer has offered in 2025.

Simon Williams, Head of Policy at RAC, highlighted that the move came after calls for retailers to cut the cost of petrol and diesel, encouraging others to make the switch. He explained: "It's great to see Asda leading the way once again with a serious price cut on its forecourts, following our call for retailers to pass on savings from lower wholesale costs. This should spark others into action and help bring down costs for drivers right across the country."

With the price cut in place, Asda garages offer petrol at around 7p less than the national average of 139p per litre, whereas diesel costs nearly 8p less than the typical price of 145.5p.

During February 2025, the cost of both fuels increased for the fifth consecutive month in a row, with drivers spending up to £80 to fill the tank of a typical family car.

The price increases have largely been due to the rising cost of oil barrels, with prices reaching $82 (£64) in the middle of February 2025.

However, Simon suggested that the cost of petrol and diesel could fall to its lowest point in four years as oil continues to trade at a lower price.

He added: "The longer oil keeps trading around the $70 mark, the more likely we are to see petrol hit its lowest price in four years.

"We're currently at an average of just under 139p for petrol and 145.5p for diesel, with both down a penny since the start of the month, but now we should really start to see that fall accelerate."

Whilst motorists cannot control the price of fuel, they can save a significant amount of money by checking for the cheapest prices in their area.

Many websites allow users to enter their location and see live petrol and diesel prices, allowing them to save several pounds each time they fill up the tank.

Careful driving habits, such as gentle accelerating and braking, and regularly checking the tyre pressures, can also help drivers improve their fuel economy, reducing the running costs of their car.
