Costco Gas Station is a membership-based fuel center offering Top Tier rated Kirkland Signature gasoline, formulated to clean engines. The gas is consistently cheaper than nearby stations, providing good value. While there is almost always a line for fuel, it moves fairly fast. The setup is convenient with pay-at-the-pump mandatory and long hoses that reach both sides of a vehicle. It is noted as much better since some parking spots were removed. The station remains open for 30 minutes after the main store closes, and going near closing time can be easier. Employees are frequently described as super nice and helpful. For some, the required wait is a reason not to purchase gas there despite the good pricing, but many find the wait well worth the savings. The overall experience is viewed as extremely easy to use.
