Costco Gas Station is a membership-based fuel center offering Top Tier rated gasoline. Its Kirkland Signature fuel is formulated to clean engines and helps vehicles run well. The station consistently offers the finest quality products at the best possible price, with gas normally cheaper than elsewhere, often significantly so. This makes the membership worth it for many. The fuel has a reputation for being high quality and burning efficiently. Only regular and premium gasoline are available at low prices; there is no mid-grade, diesel, or E85. Prices are always cheaper, though the savings can vary. Customers should be prepared for lines and note that opening hours may not always be as posted, with delays sometimes occurring in the early morning.
