Costco Gas Station is a membership-based fuel center that offers Top Tier rated gasoline, including Kirkland Signature™ Gasoline, which is formulated to clean engines and help vehicles run like new. Known for providing high-quality products at the best prices, Costco often has the most competitive gas prices, especially during off hours such as early mornings or mid-afternoons on Mondays. However, prices can vary between locations, with some stations experiencing longer lines and slower service, particularly at busy sites near Quick Quack Car Wash in Sacramento. Customers appreciate the quick service at Fairfield but note that newer stations, like the one opening in Marysville, may improve accessibility. Staff members go above and beyond, as one attendant once gave a jumpstart and pushed a customer's car to safety after a fuel-related issue. Despite occasional out-of-order pumps, many customers remain loyal due to the quality, affordability, and helpful service offered at Costco Gas Stations.
Is good service and cheap gas station. Little better long line.

Seems to be priced comparator better than most gas stations. They have a lot of islands so the wait isn’t too bad . The one thing I don’t like is they stopped having wind shield wipers cleaning materials

Best price around. Lanes usually moves quickly. Clean.
