Supermarkets have cut the cost of filling your car at their forecourts, taking up to 2p off a litre of fuel.

Asda, Sainsbury's and Tesco today announced reductions to their unleaded petrol prices of up to 1p per litre and diesel by up to 2p per litre. Asda's cut comes into effect tomorrow.

Sainsbury's is only reducing prices in certain areas, which it did not specify (see the Cheap Petrol & Diesel guide).

Tesco offers a further 5p off petrol when shoppers spend over £50 in store, or on groceries at, before 18 July.

Morrisons was the first to announce its price drop, on Wednesday, which saw diesel down by 2p and unleaded petrol down by 1p.

However, those reductions won't necessarily make supermarkets the cheapest place to fill your motor, so do a comparison on to find the best forecourt.

Average petrol prices differ nationwide, with the most expensive in London, at 119.5p a litre for unleaded, and the lowest in Yorkshire and Humberside at 117.2, according to
