Two stretches go 45 miles or more without a station within 2 miles. A station missing from OpenStreetMap would make a stretch look longer than it is, and a mapped station may have closed, so treat these as a guide.
Stations along the way
OpenStreetMap lists 298 stations within 2 miles of this route. 202 of them are in the El Paso and San Antonio areas; of the 96 in between, the most are in Fort Stockton, TX (18), Junction, TX (14) and Kerrville, TX (14).
230 of them have a brand in the data; the most common are Valero (39), Exxon (28) and Shell (24).
5 are tagged as open 24/7. Stations without that tag may still be open around the clock: the data can't tell.
| Town | Stations | From start |
|---|---|---|
| Fort Stockton, TX | 18 | 240 mi |
| Junction, TX | 14 | 437 mi |

For the first 31 miles the route runs close to the border with Mexico, at the edge of the station data, so a station there may be missing from these counts, and no stretch without stations is reported there.
How this page was made
- Route: from the centre of El Paso to the centre of San Antonio and back, each direction routed on its own, by Geoapify routing (fetched November 12, 2026). Fillerup asks for the route again when you open the trip, so its numbers can differ a little.
- Stations: every usable fuel station in OpenStreetMap within 2 miles of the route (private, disused and truck-only ones left out), from Fillerup’s station data as of November 11, 2026.
- Stops: Fillerup’s own planner, with the two vehicles above, each way from a full tank. Its picks favour stations in towns over isolated pumps, so a stop can come earlier than the tank strictly needs.
- The El Paso and San Antonio areas: within 33 miles of El Paso and 43 miles of San Antonio, the distance within which Fillerup’s route selection counts a city as part of the metro (it grows with the metro’s population), leaving out places nearer another metro’s centre or across a border.
- Not covered: fuel prices, opening hours beyond the 24/7 tag, road conditions, closures and detours.
