About Costco Gas Price DB

Costco Gas Price DB tracks pump prices at Costco gas stations across the United States, Canada, France, the United Kingdom, Australia and New Zealand. For each station we show today’s price for every fuel grade sold, along with a 30-day price history so you can spot a good day to fill up.

US, Canadian, UK, Australian and New Zealand prices are collected once daily from Costco and a number of independent sources. French prices come from the French government’s public fuel-price feed, which every station in France is required by law to report to (see Sources). Because collection happens once a day, the prices shown here can lag same-day changes at the pump. US prices are shown in USD per gallon, Canadian prices in cents per litre, French prices in euros per litre, UK prices in pence per litre, Australian prices in cents per litre and New Zealand prices in dollars per litre.

Beyond individual stations, we aggregate prices into city, state/province, and national averages, and rank the cheapest stations in each region — all rebuilt daily from the latest data.
