Costco Gas Station is a membership-based fuel center offering Kirkland Signature gasoline. The gas is Top Tier rated, cheap, and has the best prices in the area. It is formulated with additives to clean your engine. There is always a line and it is normally packed, but the line moves quickly. The station lacks windshield washing tools. Being a member is well worth it for the savings and cash back program alone, beating other fuel discount apps. Many find it a no-brainer for quality fuel at the best possible price.
