Costco Gas Station offers Top Tier rated fuel at consistently competitive prices, often significantly lower than other local options. The gas pumps are almost always busy, but the gas island is kept clean and tidy, with convenient access. Customers are requested not to tip off after the pump shuts off to maintain the cleanliness of the area. While waiting in line can be inconvenient at times, the long hoses allow customers to pump from either side. Costco is known for providing the finest quality products at the best possible price, and their fuel is no exception. The best time to visit is typically Tuesday through Thursday, especially before 11 am, to take advantage of the lowest prices.
