Costco Gas Station is a membership-based fuel center offering Kirkland Signature Top Tier gasoline. It is typically always crowded, with lines that move faster than at some other locations. There is often a wait unless visiting early in the morning or near closing, though the multiple pumps help keep wait times minimal. The station does not offer diesel. The place is described as clean and generally runs itself, with customers following the pump prompts. Attendants are noted as friendly when available, though service can sometimes be inconsistent. The adjacent Costco warehouse is spacious and well-stocked, but the parking and gas station entrance flow can be difficult depending on the time and day.
