Gasoline and diesel prices in Mexico now vary wildly between the 83 interior regions and the 7 border regions. Fuel on the border will be cheaper than most anywhere in the interior of Mexico, roughly on par with gas prices on the US border towns. The border regions are: Reynosa / Matamoros, Nogales, Cd. Juarez, Cd. Acuña, Mexicali, Tijuana etc.).
There is no way I am going to try to update fuel prices for all these areas of Mexico. So my fuel price database is history.
If you want to know more specifics about Mexico gas and diesel pricing, the official association of Mexico gas stations is Amegas. They list the prices in all of the 83 regions and 7 border regions in a PDF document. The URL will change so I will just direct you to the Amegas website and you'll have to navigate to it.
A Mexican journalist / news organization: Aristegui Noticias made a pretty neat Google map with local prices. How long she will continue to update this I don't know.
I can plan a driving trip for you, help you move to Mexico, or sell you some of my handmade maps and road logs that will help you explore Mexico as well as choose the safest driving routes. Please see what I have to offer (opens in new window). OK the commercial is over, back to your show.
In 2018, prices in all of Mexico are supposed to be on par with gas and diesel prices in the United States. I doubt it.
The state of Morelos is installed nine charging stations for electric cars, made by Nissan. Three will be on the Mexico-Cuernavaca highway.
The Mexican constitution was amended in 2014 to allow private investment in Pemex, mainly to fund exploration offshore and fracking. For years, Mexico was a net oil exporter and noted for cheap gas and diesel prices. Neither is true today.
Gas stations are independent franchises. There are more than 10,000 gas stations in Mexico. BP (British Petroleum) opened the first international chain gas station in a suburb of Mexico City, Satélite, Naucalpan, in March 2017.
Gulf Oil plans to have 100 gas stations in Mexico by the end of 2017.
All Mexican gasoline is unleaded gasoline (Magna - regular and Premium UBA - super gasoline). Magna is 87 octane. Premium gas is not only higher octane (91) but lower in sulfur (15 ppm).
I admit that there is a respected authority who says Mexican diesel is just fine. However, there are dissidents. If you drive a diesel, the next page has lots of facts on whether you should drive it to Mexico. Readers have pointed out that they have seen ULSD advertised at stations on the Pacific Coast. And with Mexico now importing about half its diesel and gasoline, your chances of getting ULSD are at least 50/50.
It it a waste of money to buy Premium gasoline in Mexico if your vehicle uses regular gas in the USA. Ditto for the aditivos (additives) that gas jockeys try to sell you. Fuel injector cleaner MAY be somewhat valuable. I used to use it all the time, but today, seldom bother.
LPG Imported from USA
LPG (liquefied petroleum gases) are growing exponentially. Mexico is adding 1,000 miles of LPG pipelines to its existing 5,000 miles.
