How to Find the Cheapest Fuel Nearby with Claude
Find cheapest fuel nearby with Claude and ToolRouter. Compare local petrol and diesel prices before you fill up.
Tool
Claude finds nearby stations and helps you decide where it is worth driving to. It calculates the fuel cost saving between the cheapest and most convenient options, factors in the distance to drive out of your way, and tells you whether the trip makes financial sense given your tank size and the price differential.

Steps
Once connected (see setup above), use the Fuel Prices tool:
- Ask Claude: "Find the cheapest petrol stations within 5 miles of [postcode or location]"
- Claude returns nearby stations with current prices sorted from cheapest
- Ask: "Is the saving worth driving to the cheapest option versus the nearest one?"
- Ask: "How much would I save filling a 60-litre tank at the cheapest versus most expensive?"
Example Prompt
Try this with Claude using the Fuel Prices tool
Find the cheapest petrol stations within 3 miles of SW1A 1AA. Show me the top 5 cheapest with current prices and distance. Calculate how much I would save filling a 55-litre tank at the cheapest versus the nearest station.
Tips
- Factor in the round-trip distance to a cheaper station — driving 3 miles extra uses roughly 0.3 litres, so the saving needs to exceed that
- Ask for both petrol and diesel prices at the same time if your vehicle can use either or if you are comparing multiple vehicles
- Ask Claude to calculate the annual saving if you fill up once a week at the cheapest versus your usual station
