The “gas station gap” of 200 miles between El Rosario and Jesus Maria is still there, but these days you’ll find “angeles” selling fuel out of gas cans at Cataviña and Punta Prieta. Expect to pay a dollar and a half more per gallon. In the winter, fierce winds in the gulf can delay the unloading of fuel barges in La Paz, which can causes shortages in Guerrero Negro, Santa Rosalia, Mulege and Loreto. But these scattered outages are getting fewer and fewer.
ULSD (UBA) ultra low sulfur diesel is now available all over the northern state. As a matter of fact, it is almost impossible to get regular diesel. The limit of the ULSD includes the gas station at Jesus Maria 25 miles north of Guerrero Negro. This means ULSD is reliably available for a distance of 425 miles south of the border. I personally checked with Pemex and further verified this fact with a pipa (tanker) driver, who was dumping fuel at the Jesus Maria gasolinera. All the fuel for this station originates at the Pemex tank farm north of Ensenada at El Sauzal.
