Esso has the largest station count of any brand we track in Calgary — over sixty locations with live prices — partly because many corner stores and 7-Eleven sites pump Esso-branded fuel. That breadth makes Esso the brand you are statistically most likely to be nearest to, and it also produces the widest in-brand price spread in the city: the gap between the cheapest and priciest Esso on the same day regularly exceeds 15 cents per litre.
Esso and Mobil stations earn PC Optimum points (the same program as Superstore), redeemable on groceries at Loblaw banners — a quiet rebate worth roughly 1–2¢/L at base earn rates and more during promos. Many Calgary Esso sites are operated by 7-Eleven, which is why you’ll sometimes see both names on our station cards: the fuel is Esso, the store is 7-Eleven.
The ranked list below refreshes hourly. As with every major chain, the cheapest Essos cluster where discount competition is fiercest — the northeast corridors, International Avenue and the Macleod Trail strip.
