Locations and distances for fuel: Bariloche to Ushuaia

[easyg]

I took the route from Bariloche South on Ruta's 40/20/26/3 and made a note of gas stations on route. All stations listed below were big YPF or Esso stations unless otherwise stated.

Gas is available at El Bolsen and Esquel after that here are your choices after that with distances between each:

Esquel
180km
Gobernador Costa
250km
Sarmienta
72km
On Ruta 26 to Comodoro Rivadavia
68km
Comodoro Rivadavia
68km
Caleta Olivia
78km
Fitz Roy
132km
Tres Cerros
137km
San Juan
120km
Comandante Luis Piedrabuena
There is a small gas station 102km from CLP but I wouldn't rely on it for gas, so...
233km
Rio Gallegos
286km
San Sebastian
72km
Rio Grande
There's another small gas station at Lago Escondido, 163km from Rio Grande, again I wouldn't rely on it, so...
209km
Ushuaia

If taking Ruta 5 from Rio Gallegos to Calafate there is a gas station 140km from Rio Gallegos at Esperanza, Calafate is a further 162km away. There is a small gas station that I wouldn't rely on for fuel 80km from Rio Gallegos on the way to Esperanza.

Riding into the wind from Rio Gallegos to Calafate I consumed 25% more fuel than riding the other direction so factor this into your calculations because you never know how windy it'll be down here.

Oh, and if you're riding from Rio Gallegos to Ushuaia it's easily possible in one day. My advice is to leave before 8am to get ahead of the busses that might slow you up at border corssings. I think the busses leave Rio Gallegos at 8:30am.

Good luck.
