Costco Gas Station is a membership-based fuel center offering Top Tier rated Kirkland Signature gasoline, formulated to clean engines. It consistently has the best and cheapest prices around, normally twenty cents to a quarter less expensive than other local stations. This leads to it always being busy, with long lines and traffic jams most days, even on weekday afternoons. There aren't enough pumps or lanes, causing waits, though expansion plans have been mentioned. The station itself is clean and safe with plenty of clean, well-lit pumps. The pump hoses are long enough to reach around any vehicle for a fast fill-up. However, some have mentioned check engine light issues and concerns about the gasoline clogging catalytic converters.
