Costco Gas Station is a membership-based fuel center that offers Top Tier rated Kirkland Signature™ Gasoline, designed to clean engines and enhance vehicle performance. Customers enjoy high-quality fuel at competitive prices, often cheaper than surrounding stations. While the fueling area is clean, long lines can be an issue, and the layout makes it challenging to navigate from the street. It's recommended to fill up before shopping, as gas lines can take time. Many customers appreciate the physical Costco card for scanning over the app's QR code. Despite the convenience and quality, the station can become overcrowded, leading to a desire for more locations in the area. Overall, it is a preferred choice for Costco members seeking reliable fuel.
