Costco Gas Station is a membership-based fuel center offering Top Tier rated gasoline, including Kirkland Signature™ Gasoline, which is designed to clean engines and help vehicles run like new. The station is known for its high-quality fuel at very affordable prices, often significantly cheaper than nearby options. Customers frequently mention the great gas prices, with some noting prices as low as $3.40 compared to $4.50 elsewhere. Despite the good prices, visitors should be prepared for long lines, especially during busy hours like Monday and Friday after 5 pm. The station has only two pumps per line, which can lead to wait times, but the lines tend to move quickly. To avoid long waits, it's recommended to visit during off-peak hours, such as early mornings or late evenings on weekdays and weekends. Traffic flow is managed by employees directing vehicles, and some lines fill from the driver’s side, which can increase wait times. Overall, customers find the wait worthwhile for the inexpensive, quality fuel and appreciate the efforts to manage traffic.
