How it works

• Helps you know which day of the week is cheapest, not just where the cheapest fuel is today.
• Enter your postcode and fuel type to see the cheapest day, based on five weeks of real data. No more guessing.
• Adjust the radius to compare more stations and find bigger savings.
• Share your discovery with friends and family.
