Costco Gas Station is a membership-based fuel center offering Kirkland Signature gasoline, which is Top Tier rated to clean engines. It provides the best gas prices around, with cheap, low-cost fuel. The station has many pumps and long hoses for convenience, but there are usually long queues with many cars in line. The station is clean and efficient, with attentive staff providing courtesy service and checking cards. However, only active Costco members can use the pumps, and it only accepts Visa credit cards. Sometimes the flow can be unclear without help.
Long lines...but... Tier 1, cheaper than anywhere else.

No matter how long the lines seem, it takes no time at all. I don't know how they do it, but they do!

Tier 1 one gasoline. Keeps your engine clean and costs the same as many stations. And YES it absolutely makes a difference. More miles per gallon and it will help clean your engine. I'll take this all day long.
