Costco Gas is available at most Costco warehouse locations and requires an active Costco membership (Gold Star $65/yr or Executive $130/yr). Pricing is typically 20-30¢/gallon below market rates at comparable stations — making the membership pay for itself in fuel savings alone for most households filling up weekly. Kirkland Signature gasoline meets Top Tier detergent standards (the same certification as Shell and Chevron) despite the lower pump price. The Citi Costco Anywhere Visa earns 4% back on all gas purchases worldwide (up to $7,000/yr in gas spend) — the highest no-gimmick gas rate available on a major credit card. For Executive members, the 2% annual reward rebate applies to Costco Gas purchases, stacking with the Citi card's 4% for an effective 6% back on gas. Payment is restricted to Visa and cash; no mobile pay or contactless is available at the pump.
