Costco Gas Station is a membership-based fuel center offering Kirkland Signature gasoline, a Top Tier rated fuel formulated to clean engines. It is known for having the best gas prices in town and tends to be the cheapest in Sonoma county. This location is noted as the largest in the area with clean, easy access, though it is situated at the back of the property. It features three pumps with long hoses allowing use of any pump, and display boards with lights show which pumps are available. The attendees are described as amazing and sweet. While prices are good, some note that lines can be long when people do not use all open pumps efficiently.
