Walmart is adding CITGO stations to Walmart+ Gas Savings, expanding the network from 13,000 to more than 17,000 U.S. locations. Members can save 10 cents per gallon at participating stations.
Walmart+ costs $98 annually. Walmart says members who used the fuel benefit at least once a week saved an average of $109 between March 2025 and March 2026.
The discount network includes participating Walmart, Exxon and Mobil stations, as well as CITGO. Most Costco fuel stations are attached to its warehouse clubs, while Walmart+ members can use participating locations across the network.
