One of the big reforms undertaken during the administration of Mexican President Enrique Pena Neto involved allowing gas stations other than government monopoly Pemex to operate freely.
A British Petroleum, or BP station has opened on Boulevard Benito Juarez in what was formerly a Pemex location. This is the first non-Pemex station in town ever.
There were many reasons stated for opening the Mexican market to companies other than Pemex. One was that the competition of other brands would make prices more competitive.
Whether that will be the case remains to be seen. However, the new BP station (on Benito Juarez a block past the rail road crossing) does currently have the lowest prices in town.
