With 13 E85 stations, San Antonio ranks among the best cities in Texas to own a flex-fuel vehicle. The highway network — I-10, I-35, I-37, I-410, Loop 1604 in particular — keeps stations accessible to both commuters and through-travelers. H-E-B operates the bulk of the city's E85 retail, and Texas has comparatively few E85-specific state incentives, so availability is market-driven — largely by Kroger Fuel Centers and a handful of regional chains.
Finding E85 in San Antonio
CleanFuel USA opened Texas' first public E85 station in San Antonio on October 19, 2005 — a genuine historical hook. H-E-B (San Antonio–headquartered) has a heavy local presence, as does Valero Corner Store / Stripes (Valero's HQ is also San Antonio). Circle K and Shell round out the mix. Federal fleets at JBSA-Lackland, Fort Sam Houston, and Randolph AFB include FFVs driven by EPAct mandates.
