Regular

all 18 stations

Kirkland Signature regular unleaded, the grade most cars are built for.

  • Costco says it carries five times the detergent the Canadian General Standards Board requires.
  • Same detergent level as premium.

Premium

all 18 stations

Kirkland Signature premium, a higher-octane grade.

  • Only needed if your owner’s manual requires or recommends premium.
  • Carries the same five-times-CGSB detergent level as regular.

Diesel

1 of 18 stations

Kirkland Signature diesel, ultra-low-sulfur like all on-road diesel in Canada.

  • Costco says its diesel additives clean deposits from fuel injectors and help reduce engine wear.

Not sold at Costco

  • Mid-grade: Costco pumps offer regular and premium only.
  • Cash sales: every Costco pump is card-only.

Is Costco gas in Quebec good quality?

Costco does not sell a refiner’s brand. Every pump in Quebec dispenses Costco’s own Kirkland Signature fuel, bought from major refiners and distributors in the region and finished with Costco’s additive package.

Costco Canada has been a listed TOP TIER gasoline retailer since December 2014. TOP TIER is the detergent standard set by automakers including GM, Ford, Toyota, Honda and BMW, and Costco says Kirkland Signature gasoline carries five times the detergent the Canadian General Standards Board requires, in both regular and premium.

In short, the low price is not a lower grade. The saving comes from Costco running its gas as a membership perk on thin margins, not from the fuel.

How Costco gas works in Quebec

Bring your card. The pump asks for an active Costco membership card before it starts, at all 18 gas bars in Quebec. Without a membership, a Costco Shop Card loaded with credit works the same way.

Pay by card. The pumps take Mastercard, debit and the Costco Shop Card. There is no cash and no Visa, the reverse of the United States.

Check the price first. Each station sets its own price, usually once a day, so two Costco stations in Quebec can differ. Today the regular average here is 173.7¢. The prices on this page are collected once daily and can lag a same-day change at the pump.

Go early or late. Lines are longest on weekend afternoons and weekday evenings. The first pumps here open at 6 a.m. on weekdays.
