Cheapest place to buy petrol and diesel near you REVEALED in ultimate interactive map... so could YOU save £10 by filling up at a different station?

Motorists could save themselves hundreds of pounds a year just by filling up at a different petrol station.

And with MailOnline's new real-time petrol price map, that challenge has now been made a great deal easier.

Using live data from more than a dozen major fuel companies, including Tesco, Asda, Sainsbury's and BP, we have created a tool so you can find the cheapest fill-up near you.

The average driver could save £10 a fill-up, or nearly £200 a year, by switching to a station that is 20p cheaper per litre – the difference between the cheapest and most expensive pumps in one area.

To use our interactive map, simply type your postcode and hit enter or click the magnifying glass to search.

By clicking the 'petrol' or 'diesel' button you can also choose which fuel type is highlighted.

You can also adjust the adjust the search radius by moving the blue slider to between one and 10 miles each side of your location. After adjusting the radius you will have to tap search again to refresh the results.

The map will then zoom to your location and highlight the cheapest petrol station (or stations) for your chosen fuel type in green. The most expensive station(s) will be highlighted in red.

Your browser does not support iframes.

Click on a marker to see more details about a petrol station, including its address, and the prices at both standard and premium petrol and diesel pumps.

You can also see information in a list view by tapping on the 'list' tab. This view will highlight the cheapest petrol station at the top in green.

When you select an item in the list, the map will open on that petrol station.

Each retailer separately updates their fuel prices together on their own schedule, but most appear to do so once or twice a day.

However, we do not control when retailers update their numbers we cannot guarantee their accuracy. You should always check the price at the forecourt before paying for petrol.

The figures come from 15 retailers participating in the Competition and Markets Authority's temporary pricing data scheme, which covers around 40 per cent of UK forecourts and 65 per cent of fuel sold.
