Louisiana drivers have long benefited from some of the lowest fuel prices in the nation, and Costco's four warehouse locations — in New Orleans, Baton Rouge, Lafayette, and Covington — typically undercut competing stations by 10 to 30 cents per gallon. Because Louisiana is a major energy-producing state, local pump prices are already competitive, but Costco membership pricing takes the savings even further. Whether you commute into downtown New Orleans or run errands around Baton Rouge, filling up at Costco can meaningfully reduce your monthly fuel budget.
Fuel prices change daily, so we do not list specific per-gallon rates here. To find current Costco gas prices near you, use the Louisiana station map to plan your next fill-up.

The diesel offered at Costco meets all federal ULSD standards and is sourced from major refineries — an important consideration if you are wondering whether Costco diesel is good quality. Louisiana's energy infrastructure means the fuel supply chain is robust and well-integrated. For truck owners looking to protect their investment, adding quality diesel fuel additives can enhance lubricity and clean injectors.
