Estación de Servicio Shell Malargüe Ruta 40

Modern Shell station at the junction of Ruta 40 and Ruta 186, serving as the last reliable fuel for overlanders heading south into the Payunia Reserve or west toward the Chile border. Full services including diesel, premium gasoline, propane exchange, and a decent mini-market with basic camping supplies. Bathrooms are clean and they’ll let you top off water bottles.

This is your final fuel for 200+ kilometers if heading toward Bardas Blancas or the remote volcanic zones. Stock up here — the next reliable fuel is either back north in San Rafael or south in Barrancas. Station stays open late during peak season but verify hours before making evening runs.
