Costco Gas Station is a membership-based fuel center offering Top Tier rated Kirkland Signature gasoline, formulated to clean engines. The price is consistently the cheapest and most reasonable in the area, leading to significant savings. This makes the wait, which is often present due to multiple lines of cars, generally worth it. The lines, however, usually move quickly and the process at the pump is easy and fast. The station is reliable with pumps rarely out of order. It is clean and the attendants are professional and helpful. A noted downside is that the location can be inconvenient to enter or exit. It is recommended as a primary refueling stop and a key membership benefit.
