Costco Gas Station is a membership based fuel center offering Top Tier rated Kirkland Signature gasoline, formulated to clean engines. The prices are consistently much better for members, offering fair and great gas savings that help in the pocket book. The station is always super clean, with attendants always there to help if needed and to promptly clean any spills, which makes customers feel safe knowing someone is keeping an eye on things. While the location is usually packed and can have pretty long lines at times, especially as it is within the shopping parking lot which can cause quite the backup, there are plenty of pumps to keep lines moving. To avoid waits, it is best to go early in the morning or mid-afternoon when lines are short or don't exist, or before the store opens. The station has diesel pumps on the left in two or three lanes.
