Costco is known for offering some of the most competitive fuel prices in Kentucky, typically undercutting nearby name-brand stations by 10 to 30 cents per gallon. Whether you are filling up in Louisville, Lexington, or Florence, the savings at the pump can add up quickly — especially for drivers who commute daily or operate fleets. Costco's buying power and membership model allow the warehouse club to pass along wholesale-level pricing to its members.
Because gas prices fluctuate daily based on crude oil markets, regional supply, and local competition, we do not post specific per-gallon prices on this page. Instead, use our interactive Kentucky fuel map to find the nearest Costco gas station and check current pricing during your next visit. Compared to major brands like Shell or BP, Costco's fuel often represents a better value for everyday drivers.
Kentucky currently has 1 Costco location with diesel fuel — the Florence warehouse off I-75. This is good news for diesel drivers in the northern Kentucky and greater Cincinnati area. However, if you are in the western or central parts of the state, diesel access is more limited. Costco is gradually expanding its diesel offerings across its network, so additional Kentucky locations may add diesel pumps in the future.
The diesel sold at Costco is ultra-low sulfur diesel (ULSD) that meets all EPA requirements. Many diesel truck owners and RV enthusiasts wonder about whether Costco diesel is good quality — the short answer is yes, Costco sources its fuel from major refineries and includes detergent additives that help keep injectors clean. For drivers interested in maximizing engine life, pairing quality fuel with the best diesel fuel additives can further improve performance and lubricity.
Costco gas stations in Kentucky typically operate from 6:00 AM to 10:00 PM on weekdays, with slightly reduced hours on weekends. Hours may vary by location and season, so it is always a good idea to verify before making a special trip. A valid Costco membership is required to purchase fuel — this is enforced at the pump by membership card readers. Executive members earn 2% cash back on qualifying gas purchases, subject to an annual cap, which can make the already-low prices even more rewarding.
