Mobil in Calgary is a discount play in major-brand clothing. Most local Mobil sites are the rebranded gas bars at Real Canadian Superstore locations plus a handful of standalone stations, and they price aggressively — typically below Shell, Petro-Canada and Esso, and within a couple cents of Co-op. Like Esso, Mobil participates in PC Optimum, so every litre earns grocery credit on top of the low posted price.
Because the network is small, which Mobil is "cheapest" matters less than whether one sits on your normal route — the Superstore-attached sites in the northeast, west and deep south are the busiest. The ranked list below shows each tracked Mobil with its live price, refreshed hourly.
