LOL! I’m in Toronto. Gas at Costco is usually $0.05 less than at regular gas stations. I filled up there this morning. They have three long lines of cars waiting for an available pump. This morning an SUV in the middle lane ran out of gas while still six or seven cars from the pump! That must have happened before because the attendant produced a can and they took a minute at one of the pumps, between cars, to fill the can. Then they walked to her car. Gas was $132.9 per litre for regular 87 octane.
We usually keep a fairly full tank to protect ourselves from power outages and also to keep condensation to a minimum. The penalty is dragging around the extra weight in stop and go traffic.
