Gas is one of the hardest expenses to avoid when you own a vehicle. But between paying for the most expensive fill-up in your area and paying the least while burning less fuel, the gap adds up to hundreds of dollars a year. Here are ten concrete moves to shrink your gas bill in Quebec — from the simplest to the most technical.
Ten ways to save
- Compare prices before filling up. It’s the easiest and most immediate saving. Prices vary sharply from one station to the next, even a few streets apart. Check the average prices by region or spot the best stations around you on the price map before committing.
- Use rewards programs. Several banners offer per-litre discounts or loyalty points. Accumulated over a year, those few cents per litre end up worth several fill-ups. Pick the program(s) matching the stations you already visit.
- Don’t pay for premium without a reason. If your vehicle is designed for regular, premium brings nothing — no power, no efficiency, no “cleaning”. It’s pure expense. We explain why in our guide regular or premium: which to choose?
- Drive smoothly. Hard acceleration and braking waste fuel. According to Natural Resources Canada, aggressive driving can raise consumption by up to 39% on the highway. Anticipate traffic and drive gently.
- Ease off on the highway. Driving at 100 km/h instead of 120 km/h lets you, according to CAA-Québec, burn roughly 20% less gas, for a barely longer trip.
- Keep your tires properly inflated. Under-inflated tires increase rolling resistance and consumption. Check the pressure monthly, cold, against the manufacturer’s recommended value — especially important when Quebec’s cold weather drops the pressure.
- Lighten the vehicle and remove unused accessories. Every extra 25 kg raises consumption by about 1%, according to CAA-Québec. Empty the trunk of anything unnecessary and take off roof racks and boxes when you’re not using them: they hurt aerodynamics.
- Avoid idling. An engine running while parked burns fuel for zero kilometres. If you’ll be stopped for more than a minute (outside traffic), shut it off: restarting costs less than idling.
- Plan your trips. Grouping several errands into one outing avoids multiple cold starts, which burn more. A well-planned route means fewer kilometres — and less gas.
- Fill up at the right time. Prices move in cycles. Filling up before an increase rather than after can be worth several cents per litre. We explain how to spot the moment in our guide on the best time to fill up.
What about discount stations?
Beyond these ten moves, it’s often worth looking at discount stations and big banners like Costco, which frequently post prices below the average. The per-litre saving is real, but it depends on how close you are and, in some cases, on a membership. We run the numbers in our guide Costco and discount banners: are they worth it?
The habit that pays the most
If you remember only one thing: compare before you fill up. It’s free, immediate, and requires no change in how you drive. Combined with smooth driving and a well-maintained vehicle, you attack the bill on both fronts: the price per litre and the number of litres.
Frequently asked questions
What’s the most effective way to save on gas?
Comparing prices before every fill-up. It’s the fastest saving, with no effort or habit change, and the gaps between stations are often surprising.
Are rewards programs actually worth it?
Yes, especially when tied to stations you already visit. Per-litre discounts or points add up and can amount to several free fill-ups over a year.
Does driving slower really make a difference?
Yes. Air resistance climbs quickly with speed: driving at 100 km/h instead of 120 km/h can cut highway consumption by about 20%, for a minimal time cost.
