Pemex Acayucan Autopista del Golfo

This large Pemex station sits at the critical junction where Mexico 180D meets the turnoff toward Tuxtla Gutiérrez and the Chiapas highlands. Clean facilities, reliable diesel, and Magna Sin premium gasoline make it a solid fuel stop before tackling mountain grades. The attached convenience store stocks basic provisions, cold drinks, and surprisingly decent coffee. Truck parking area works for larger rigs, and there’s usually space to maneuver even with a trailer.

Open 24 hours, which matters when you’re timing border crossings or trying to beat mountain weather. Can get busy with commercial traffic during peak hours, but turnover is quick. Credit cards accepted, though cash is always faster in Mexico.
