With the national average now topping 100p a litre for petrol and 105p for diesel, whatcar.com is on the look-out for Britain's best and worst fuel deals.
Word has already reached us of an outlet in Merseyside that is charging 114p for a litre of diesel, while one retailer in Hertfordshire wants £108.9p for a litre of petrol.
In contrast, there are reports of petrol costing as little as 94.9p in parts of Scotland, and diesel at 99.9p in Northampton.
As a result, someone switching from the most expensive to the cheapest fuel station could be saving around £7 a tank.
We want to know if your local petrol station is charging more or less than any of these figures - and we'll publish the results.
Just let us know the station's name, location and the prices it's charging by clicking here.
