Costco price distribution
Station counts show how many matched stations have a listed price for each fuel grade. Matching can use the fuel brand, operator or station name, so totals can differ from the retailer index's primary retailer grouping. They are not the retailer's total estate.

Before you fill up
A fuel price is useful only when you know the grade, when it changed and whether the extra journey is worth it.
What is the average Costco petrol price?
The latest Costco E10 average is 166.2p across 22 recent station prices. Local stations can be higher or lower.
Are Costco fuel prices the same at every station?
No. Listed Costco petrol and diesel prices vary by station, fuel grade and when the price last changed. Search your postcode rather than relying only on the UK-wide average.
How do I find today's Costco petrol or diesel price near me?
Enter a postcode on this page to compare nearby Costco station prices, distance and last-updated times. Open a station result for details and directions.
Is Costco always the cheapest?
No. Prices vary by station, region, fuel grade and date. Compare the local price and route rather than assuming a chain is always cheapest.
How do I check Costco’s petrol grade?
Check the product label at the pump and Costco’s official fuel information for your station. E5 describes ethanol content; it does not by itself confirm 99 RON. Choose the octane grade required by your vehicle.
