Costco Gas Station is a membership-based fuel center that sells Top Tier rated gasoline, including Kirkland Signature™ Gasoline, which is formulated to clean engines and help vehicles run like new. Known for offering the finest quality products at the best prices, Costco’s fuel is competitively priced, often the lowest in the area, especially with extra discounts like the 4% off for Citibank Costco cardholders. The station is generally very clean and has about 24 pumps, which helps reduce wait times despite occasional long lines. It offers diesel fuel and has great hours of operation. The Santa Maria location has more pumps than nearby stations and features helpful indicators on top of the pumps. However, some users find the entrance narrow, which can block larger vehicles from entering. Overall, Costco Gas Station provides good prices, quality fuel, and a convenient experience, though wait times can vary.
