Costcoâs gas stations have become one of the clearest signs that American shoppers are still hunting aggressively for savings as fuel costs climb. The warehouse retailer said gasoline demand reached record-breaking levels in its fiscal third quarter, with drivers turning to Costcoâs lower-priced pumps as pressure from higher energy prices continued to squeeze household budgets.
The surge was not limited to a single busy weekend or one region. Costco said the final five weeks of the quarter brought exceptionally strong fuel volumes, forcing many locations to manage repeated gasoline deliveries throughout the day. For a retailer already known for value, cheap fuel has become a powerful reason for members to visit more often.
Chief Executive Ron Vachris told investors that the war in the Middle East had a significant impact on fuel prices and product supply. That pressure made consumers more sensitive to gasoline costs, helping drive first-time visits to Costco gas stations from members looking for relief at the pump.
The bigger advantage for Costco is what happens after drivers fill their tanks. Management said customers who buy gas often spend more inside the warehouse, turning fuel traffic into broader shopping activity. That gives Costco a benefit many traditional retailers do not have: a low-price fuel offer that can pull shoppers into stores even when inflation is forcing families to be more selective.
The companyâs latest numbers show that the strategy is working. Costco reported fiscal third-quarter revenue of $70.53 billion, ahead of Wall Street expectations of $69.62 billion. Adjusted earnings per share came in at $4.93, also slightly above analyst estimates of $4.91. Comparable sales rose 9.8% overall, including 9.4% growth in the United States, 10.7% in Canada and 11.2% across other international markets.
Membership fees added another layer of strength. Costco generated $1.37 billion from membership income, slightly higher than expectations of $1.36 billion. That matters because membership revenue supports Costcoâs low-margin retail model and helps the company keep prices competitive on essentials, fuel and household goods.
Still, the headline growth needs context. Excluding gasoline, comparable sales increased 6.6%, just below the 6.7% analysts had expected. That shows fuel played an important role in the quarterâs performance, even though Costcoâs U.S. business still performed better than expected without gas included.
Inflation trends were mixed across the business. Costco said lower prices in produce, eggs and dairy helped ease pressure in food and sundries. At the same time, the company warned that higher resin costs could eventually push up prices for some non-food products. It is also watching the longer-term impact of oil prices and tariffs on supply chains, transportation and finished goods.

The latest report underlines why fuel has become a strategic advantage for Costco rather than just an add-on service. When gas prices rise, shoppers have a fresh reason to renew memberships, visit warehouses and compare Costcoâs pump prices with nearby stations. That can strengthen loyalty at a time when many consumers are cutting back elsewhere.
