Costco has streamlined the experience of fueling up at its gas stations by implementing a one-way traffic system. This innovative approach allows drivers to fill their tanks more efficiently, significantly reducing wait times and enhancing customer satisfaction. The design features extra-long hoses that can reach either side of vehicles, eliminating the need for drivers to maneuver into specific lanes.

Enhancing Convenience for Members

As part of its commitment to convenience, Costco has extended its gas station hours as of February 2025. This move complements additional services offered at their fuel stations, such as free nitrogen tire refills and tire maintenance. These initiatives are designed to make errands easier for Costco members by allowing them to complete multiple tasks in one visit.

Many drivers, especially those who do not hold Costco memberships, often express frustration at traditional gas stations where fuel tank placement can complicate the fueling process. The inconsistency in fuel tank locations leads to confusion, with many questioning why not all vehicles have their tanks on the same side. According to a report by IDriveYourCar, in 2020, approximately 78% of cars sold had fuel tanks on the left side, while 22% were on the right. Notably, only 1% of Toyotas and 2% of Fords had right-sided fuel tanks, while brands like Honda, Hyundai, and Kia had none at all.

Understanding Fuel Tank Placement

The design of fuel tanks is not arbitrary; it reflects various factors, including national driving norms and vehicle safety. Bharat Balasubramanian, former head of research at Mercedes-Benz Group AG, explains that the placement of gas tanks on the right side for some vehicles, including many Mercedes models, stems from the right-hand traffic systems in Germany. On German highways, fuel stations are typically located on the right shoulder, prompting manufacturers to position tanks accordingly for driver safety.

Interestingly, vehicles from other manufacturers also exhibit varied tank placements, with all Land Rover, Porsche, and Volvo models sold in 2020 featuring tanks on the right side. This diversity underscores the complexity of vehicle design and the influence of regional driving habits on manufacturing choices.

As consumers navigate their fuel options, understanding their vehicle’s fuel tank position can make a significant difference in efficiency and convenience. For those uncertain about where their gas tank is located, simple visual checks or vehicle manuals can provide clarity.

Costco continues to prioritize customer experience, and its one-way gas stations exemplify a thoughtful approach to modern fueling practices. By addressing common frustrations and enhancing convenience, Costco sets itself apart in the competitive landscape of fuel services, solidifying its reputation among members and drivers alike.
