  • Cash sales: every Costco pump is card-only.

Is Costco gas in London good quality?

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