Costco Gas Station is a membership-based fuel center. It sells Top Tier rated Kirkland Signature gasoline, which is formulated to clean engines. The gas is consistently less expensive than other vendors, often by 10 or 20 cents. It is generally cheaper than most places. The best times to go are early in the morning before the store opens or around 2:00 pm to avoid the long lines that form, especially on weekends when they close early. The associates keep the lines organized and moving fast. They also open early hours. While the gas station is great, there have been some issues with other store products like bad vodka, moldy cheese, and specialty cakes with problems, but the fuel remains a key membership benefit at a great price.
Costco Solemia is the best gas station because it has three stations on each side, making it much easier and faster to get gas.
