Is the cheapest station actually worth the detour?
Today in Longueuil, the gap between GazGain's tracked average and the lowest price is about 6.2¢/L. On a 45 L fill-up, that is $2.79 before counting the fuel burned to get there. GazGain calculates that real gain with your vehicle, tank level and position.
The simple formula
Gross savings = litres × price gap
Detour cost = km × consumption
Real gain = gross savings - detour cost
Why prices vary in Longueuil
In Longueuil, comparisons with Montreal, Brossard and South Shore corridors matter. The lowest price is not always the best stop if the detour adds time and fuel.

Is the cheapest gas station always worth the drive?
No. The real savings depend on how many litres you need, the detour distance and your vehicle's fuel consumption. That is the calculation GazGain does in the tool.
How should I compare Esso, Petro-Canada, Ultramar or Shell in Longueuil?
Compare the per-litre gap first, then the real driving distance to the station. A cheaper brand in Longueuil can be the best stop when it is already on your route; it can cost more when the detour is too long.
Can I compare premium or diesel in Longueuil?
Yes. Use the same calculation with the fuel price you actually buy and your vehicle's real fuel economy. The detour fuel still has to be subtracted from the per-litre savings.
