Is Costco gas in Ottawa good quality?

Costco does not sell a refiner’s brand. Every pump in Ottawa 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 Ottawa

Bring your card. The pump asks for an active Costco membership card before it starts, at all 3 gas bars in Ottawa. 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 Ottawa can differ. Today the regular average here is 152.9¢. 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.
