Costco Gas Station is a membership-based fuel center. It sells Top Tier rated Kirkland Signature gasoline, which is formulated to clean engines. Prices are always the lowest and most competitive, often 20 to 30 cents less than other stations. The location is always packed during rush hour, with waits over 15 minutes, but is a breeze at other times. Attendants are friendly and helpful. Lines can be long, but people are usually respectful and courteous while waiting. It is for members only, and many find the membership worth it for the fuel savings.
