About Costco Fuel
Costco Wholesale operates fuel stations at most of its warehouse locations, offering some of the consistently lowest gas prices in America. Costco's massive purchasing power allows it to undercut traditional retail stations by 10-25 cents per gallon. Costco fuel meets TOP TIER detergent standards and is the same quality as brand-name alternatives at a significant discount.
Costco Loyalty Program
Costco membership required ($65/year individual or $130/year Executive). Executive members earn 2% back on all Costco purchases including fuel. For a family filling up weekly, fuel savings alone often exceed the membership cost.
