What is Mexico's main energy resource?

Answer 1

Mexico's petroleum industry is wholly government owned. "Petroleos Mexicanos" (PEMEX for short) manufactures, distributes and sells motor fuels and lubricants, within a state owned monopoly. It might surprise you to learn that Mexico now imports about two-thirds of its gasoline from the USA. Almost all gasoline sold in the northern half of the country is US refined fuel. Gasoline stations (referred to, as "gasolineras" are extremely common. They are franchise operations, with the franchisee providing the land the electricity and the manpower to operate the station. Some of the newest PEMEX superstations in central Mexico have integral mini-marts, car wash, and lube and oil changing facilities. Two grades of gasoline are sold in Mexico Regular and Premium: Mexican gasoline does not use the controversial MTBE additive. No Mexican automotive gasoline contains even the slightest trace of lead additive. Mexican aviation gasoline will not be dispensed to anyone not possessing a valid aircraft manifest (there goes your plans to fuel up that ultra-high compression dune buggy)
