Fuel prices at Costco Chester cover standard Unleaded, Premium Unleaded and Premium Diesel, putting it in direct competition with supermarket forecourts and the big branded stations nearby. This is pump fuel rather than a packaged product, so the main thing you are comparing is the per litre rate and whether you can access the site at the times you need.
Who is this for?
Regular drivers who can use the Chester warehouse will get the most value, especially if you already factor Costco into your weekly route. Premium grades can suit cars that recommend higher octane petrol or drivers who prefer premium diesel for longer motorway runs, but check your owner’s manual first, many engines see little benefit from paying extra. As ever, the real saving depends on how far you travel to fill up and how busy the forecourt is at peak times.
