Current Fuel (Gasoline and Diesel) Prices in Mexico
Gasoline and diesel fuel prices increase a few centavos a month in Mexico
Gasoline and diesel prices in Mexico will continue to increase slightly every month in 2015. Mexican fuel prices increase a few centavos a month regardless of market fluctuations. So for the foreseeable future (oxymoron?) gas will cost more in Mexico than in the USA. Diesel fuel used to be cheap, but is no longer subsidized, and is similarly-priced to USA diesel.
The state of Morelos is installing nine charging stations for electric cars, made by Nissan. Three will be on the Mexico-Cuernavaca highway.
Mexican fuel prices increase by the 10th of each month. Overall, the cost of gasoline is less than in many states in the USA. The Mexican constitution was amended in 2014 to allow private investment in Pemex, mainly to fund exploration offshore and fracking. Cheap gas and diesel prices in Mexico used to be kept artificially low but since Mexico is now a net oil importer, those days are gone.
Gas stations are independent franchises. There are more than 10,000 gas stations in Mexico. Starting in 2016, new, independent (international) franchises will be allowed to set up chains in Mexico.
2014, the value-added tax or IVA was raised on the border regions to equal that of the rest of Mexico (16%). This almost ended years of subsidized lower gas prices on the borders. However, some border towns still had differently-priced (less expensive) gas than those in the interior.

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.
Fuel costs (unleaded gasoline, UBA, diesel or low-sulfur diesel) in Mexico are often less than in much of the USA - and more expensive than in some states. It all depends on where you are standing. On the border, gas may be less in the USA than in Mexico - certainly in Texas. If you are from the northern USA or the West Coast, fuel in the interior of Mexico will be less expensive for you. However, gas prices fluctuate greatly in the USA. During times of inexpensive crude on the international markets, USA prices will be way less than Mexican prices since gasoline and diesel prices in Mexico are fixed. However, things always even out in life. When crude oil is selling for over a hundred dollars a barrel, you can bet Mexico gas will seem like a bargain. Regardless, fuel costs what it costs. You'll have to pay whatever the asking price is wherever you are.
For current (mostly) fuel costs in Mexico, see the Mexican fuel price page. Gas and diesel fuel prices are quoted both in Mexican pesos and in US and Canadian dollars. I try to update it once a month, which is all it needs. But I am often remiss. The price changes are not significant, but a few centavos per liter per month. Unless you are buying a consultation, please don't write to ask me the current price of fuel. Thank you.
When US gas prices fluctuated a few years ago, Mexican gas and diesel prices stayed stable.
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 have not gotten a straight story from Pemex or from the few gas station owners I know. But a reliable source in Mexico City to me that there is ultra low sulfur diesel (DUBA-- 15 ppm) and low sulfur Mexican diesel fuel (LSD [seriously]-- 30 ppm, depending on what state you are in. But all diesel is called low sulfur - you won't see anyone touting Diesel Ultra Bajo Azufre.
As of April 2014, there still is not any ultra-low-sulfur diesel outside a limited area around Mexico City and Mexico state.
Ultra low-sulfur diesel (DUBA) has only 15 ppm of sulfur. It has 5% biodiesel so it has more lubricity. We all know that is a good thing. It was introduced to 50% of the Pemex stations in central Mexico (Mexico City, Morelos, Puebla, Mexico and others). It is being slowly introduced to a few stations in the rest of the country. Look for the sign, "bajo azufre" below the word "Diesel" on the gas station signage.
But I have to be honest with you - don't count on finding ultra low-sulfur diesel in Mexico. If you are afraid of putting plain low sulfur diesel in your tank, then don't drive to Mexico with your diesel vehicle.
I do not drive a diesel vehicle. So do not take your newer diesel vehicle to Mexico on my word for anything. Check with your mechanic, your dealer (there's that LSD link again) and your spiritual advisor and then make up your OWN mind. I know many owners of older (pre-2008) diesel pickup trucks and they are happy using Mexican diesel.
I talked to a corporate representative from Ford, Mexico and he insists that the diesel in Mexico is low-sulfur and can be used in the newest trucks produced in Mexico. I'm not taking sides, just reporting what i have been told.
For newer diesels, still in warranty, here is what RAM trucks told me:
Dear Mr. Mike Nelson:
Thank you for contacting the Chrysler Customer Assistance Center.
If the proper maintenance or fuel is not used and it has been determined by our Chrysler dealer or technical personnel that failure was caused by improper fuel usage, then YES the factory warranty would be voided.
Now, how would they determine that damage occurred by improper fuel usage? You'd best ask a trusted mechanic or two for a good opinion on that one.
Some Mexico travel blog contributors say that they have driven a couple of thousand miles on the "regular" diesel in their newer RVs requiring ultra low sulfur diesel with no ill consequences. However, the site fueleconomy.org says that LSD will make your engine hallucinate. At least they sternly say not to "just say NO" if you have a 2007 or later vehicle. And it COULD void your warranty.
Baja supposedly has low sulfur diesel (not everywhere, though). Talk to a competent diesel mechanic about the effects of using fuel with higher sulfur content on your engine before deciding to drive a newer (2007 and up) diesel vehicle to Mexico.
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.

I've seen some RV bloggers suggest you drive over the Mexican border to fill up with diesel. Driving across the Mexican border just to fill up and driving back to the States is false economy, since you must have Mexican RV or auto insurance and will have to wait an hour or more in line at the Mexican border. Plus you need a passport to reenter the USA.
However, both gasoline and diesel costs still vary by regions of Mexico, even after the increase in the IVA. This is a little-known (as heard on the TV show Cheers) fact and likely to lead to different people swearing that the cost of gas or diesel is different than someone else. Some (not all) border towns still have competitive prices with their USA counterparts. The Mexican gas and diesel prices on the next page are based on the cost of unleaded and high octane gasoline and diesel in the majority of Mexico.
