There is a Shell gas station in my neighbourhood whose price is always about 4 cents/litre (works out to 11.2c/american gallon) less than the prices at the other brand name stations. Not surprisingly there is always a lineup of cars at this station.
Is there any reason why I should not buy gas from this place? Obviously it is a high volume gas station and, being Shell branded, must be selling the same top tier gas as the other Shell stations. I am hoping Shell enforces maintenance standards at all their outlets regarding dirt and water contamination.
