Costco Gas Station is a membership-based fuel center offering high-quality, Top Tier rated Kirkland Signature gasoline, formulated to clean engines. It provides inflation-beating prices for its quality fuel. The stations are clean, modern, and staffed by helpful and nice attendants who work efficiently to get customers in and out quickly. The staff are willing to assist as needed, demonstrating amazing customer service, including helping with filling multiple containers and offering practical tips. While the gas is a reasonably priced perk with long hours, a noted drawback is that the technology sometimes requires updating to allow verification of membership through the Costco app, meaning customers with only a digital card may need to flag down an attendant. The layout, with many pumps, occasionally leads to congestion as some customers choose pumps on the wrong side of their vehicle, creating minor delays. Overall, it is a great gas station known for its solid service and value.
