Frequently Asked Questions

Our collection job checks for new station reports every hour. A station's price only changes when someone reports a new one, so each price shows the time it was reported. Reports up to 36 hours old count as current; reports from the last 12 hours rank ahead of older ones in every "cheapest" list, and anything older is marked as out of date.

Pump prices come from community-reported Canadian fuel-price feeds, mainly public GasBuddy reports, each with its own report time. We do not collect prices by hand. The daily forecast also uses WTI crude (U.S. FRED) and Edmonton wholesale rack prices. See the About page for the full methodology.

A price is only as current as its last report. We don't measure how far reports drift from the pump, so treat older reports with care: check the report time next to each price, and always confirm the pump price before you start filling.

We cover the major chains: Shell, Petro-Canada, Esso, Co-op, Costco, Husky, Pioneer, Canadian Tire gas bars, and more. Coverage depends on what's included in our data provider's database. Independent or very new stations may be missing. If you notice a gap, please use the Contact page to let us know.

No. If you use the "Nearest to Me" feature, your GPS coordinates are used only within your browser session to find nearby stations. We transmit them to our API server (over HTTPS) solely to filter the station list by distance. We never store, log, or sell your location data. You can also search by postal code to avoid sharing your GPS location entirely.

This happens when our data provider doesn't have a current price for a particular station. It can also happen with very small independents, recently opened locations, or stations that rarely appear in community price reports. We still show the station's location on the map so you can check the price in person if it's nearby.

Yes! Use the Contact page to submit a correction. Include the station name, address, and the correct price you saw at the pump. We'll flag it to our data provider and update the record as soon as possible.

Yes, where stations report them. Regular (87 octane) is the default across the site, and there are dedicated pages for the cheapest diesel and premium prices in Calgary. Each station page also lists mid-grade, premium and diesel prices when they have been reported.

No. We are a completely independent comparison tool. No gas station, fuel company, or refinery has any ownership stake in this site or pays us to rank stations in a particular order. Stations always appear sorted by price (cheapest first) and/or distance — nothing else.

Costco gas bars in Calgary are often among the cheapest options in the city, and are frequently several cents per litre below the major branded stations. They buy fuel in very large volumes and operate their gas bars as a member benefit rather than a profit centre. The catch is you need an active Costco membership to purchase fuel there.

Canadian gas prices are quoted in cents per litre (¢/L). One US gallon equals approximately 3.785 litres. So if Calgary gas is 170 ¢/L ($1.70/L), that works out to roughly $6.43 per US gallon — for context when comparing with American prices.
