Calavera:
Avoid old gas stations, never buy in a gas station where you see a pipetruck downloading "fresh" gas to the underground tanks.
When buying from rural re-salers, always put a handkerchief (pañuelo) in your tank mouth to filter all dust, but first see if it contains no water.
The octane ratings of Mexico do not fit exactly with the US, think about substracting up to 5 points to the rating advertised in the pump.
In small towns the Hi-Octane type could be pretty old since very few people buy it, so maybe the lo-octane could be a better choice.
