The Fairfield Costco gas station sits just off Highway 12, making it easy to access for commuters heading to Napa, Vallejo, or Vacaville.
This location completed a major expansion in late 2023 that doubled the station’s capacity. The upgrade added 12 new fueling positions, a 30,000-gallon underground fuel tank, and improved traffic flow.
With the expansion complete, members now enjoy shorter wait times and faster service. The station pumps TOP TIER certified gasoline, the same quality fuel sold at premium brands.
