Costco Gas Station offers high quality gas at prices that are usually much cheaper than surrounding stations, often by 20 to 50 cents per gallon. The gas is very reasonable and lasts longer. It is a member-only facility with plenty of lanes, though it can be crazy busy and congested. Friendly attendees provide quick service. Some note the gas nozzles are sensitive and click off, and that traditional services like window washing are not available. Despite the busyness, it is considered worth the wait for the best prices and reliable fuel.
