Post Mexico Fuel/Gasoline Treatment

AustA - 1-24-2014 at 08:37 AM

Okay I have heard for years that Mexican gasoline is bad for your vehicle. I know people that live in TJ and commute to SD for work and they fill their cars with American gasoline because the Mexican gas is not good for vehicles according to them. Is this true?
If the gas is not good for the vehicle, does anyone have a suggestion on what to do for your vehicle after burning Mexican gasoline? My friend replaces his fuel filter every few years post trip.
Any feedback is greatly appreciated.

It's fine. Never had any problems.

I don't know but I used PEMEX gas for about a year until I started back buying US gas because of the rumors of problems with PEMEX. I did not have any problems with the PEMEX gas.

It appears the cars belonging to MX citizens run for many years on PEMEX. I don't see cars broken down all over the place. Many of the broken down cars I see appear to have many other problems going on.

I heard recently that PEMEX gas is more expensive than US gas at present. I find that hard to believe.

From what I understand the big difference between US gas and Mexican gas is that Mexican gas does not have alcohol, so you get better fuel mileage!!! I do get better mileage down here than I do in the states. But the driving conditions are substantially different. I have a little over 40,000 miles driving in Mexico and never had a fuel related problem.

Happy Trails

Mexican gas is more expensive than gas in a lot of the US. It is 12.32 Peso's a liter which converts to about $3.45 at today's exchange rate of 13.5242.

I use to always have a spare fuel filter but haven't needed one for over 10 years so I think Pemex is good.

Pemex is not only good, but it is better than what California forces us to use. No ethanol diluting Pemex gas, so instantly better mileage and better for the car, the economy, world food needs, and the ecology of our planet!

Pemex has no ethanol in it and it, therefore, gives you better mileage. In my F150 that is about a 15% increase from an average of 13.6 in California to about 15.5 in Baja. I am a numbers freak so I keep records of gallons in against miles driven and my 4X4 F-150 gets that lousy 13.6 MPG on average up here over the last 105,000 miles. BTW the Ford digital readout of mileage in the instrument panel is a damned lie....inflates the mileage about 20%. The window sticker on my F150 said it would get 18 MPG on the highway and 14 around town...doesn't. Ford told me that the difference was due to the fact that my truck is a 4X4 and the gummint imposed the sticker mileage figures after "testing" and the same number was used for 4X4s and 4X2s.

BTW, here's how to tell if there is ethanol in your gas: steal a glass cup measure from your wife and put a half cup of gas in it. Then add two ounces of water and shake the cup. The gas is lighter and it will be on the top of the cup and the water will be on the bottom.....2 ounces of water just as you added it.

BTW, the price of corn in the midwest went down to $4.40/bushel from $6+ per bushel last December when the &*^%#%^ gummint announced that they would not require an increase in the ethanol in gas from 10% to 15% next year. That was good for us because Detroit pointed out that the increase would harm most autos.

I have lived in Ensenada for over 10 years and burn nothing but Pemex in all 3 of my vehicles. They all have fuel injection and I have never had a fuel related Problem.
Belive it or not Gasoline in some places in San Diego is a few cents cheaper than here.
I never use any kind of additive in in my fuel,most of that crap is made to sell and is of little or no benefit to your vehicle

It's a "night and day" difference with the Pemex gasoline that's produced for consumers today in comparison to the Pemex gasoline of 25-30 years ago. But moreso with the product quality. I perceive it's only slightly better today in the handling of the product through the supply chain.

As far as the quality is concerned with the gasoline (I can't speak for Diesel) available today from Pemex, it is perhaps better for vehicles than the gasoline available in California (USA). It may not be better for the groundwater, but it runs better in the vehicle. This has to do with the use of MTBE.

The handling of gasoline in the supply chain is another story entirely. From a consumer standpoint, there are - rightly so - sometimes concerns about certain stations. Pemex, I believe, has improved standards and inspections, but I believe there are still some opportunities for vendors - who are less concerned about the quality of the product - to take advantage of their customers.

As of around January 1, the price of Pemex gasoline - at least in Baja - became a little more expensive than that in California, USA.

Mexico exports crude oil(via tanker boats, pipelines and trucks) to the PEMEX-Shell joint venture refinery at Deer Park Texas.

After refining into unleaded gasoline (without ethanol) and diesel it is shiped back to mexico (not just Baja) and accounts for nearly 40% of Mexico's fuel supply.

baja VS ca gas

captkw - 1-24-2014 at 09:44 AM

We have down this road here before !! the mex gas is better for motors than the gas with ethanol from ca...simple,,simple...20 something years ago was anther story !!

55steve - 1-24-2014 at 09:50 AM

The shelf life of Mex gasoline typically is much longer than the Ca. fuel - I've found the Ca. fuel goes bad in about 2.5 months whereas the Mex fuel has been usable for at least 6 months+. This is in my boats.

Take a close look at what Bob Durrell said and his source.

Many of us have know this fact for several years.

a bit short-sighted to focus on personal vehicle mpg.

the gasoline in socal has additives that improve our air quality. do you remember the 1960s and 1970s air quality in socal? i think emissions controls and gasoline formulations (and other pollution control efforts) have vastly improved socal air quality from the 1960s and 1970s when air quality was horrendous.

when you have so many millions of people living in socal, air pollution control efforts are necessary to maintain air quality.

look at the results: air quality has greatly improved in past 40 years at same time the population has risen. nothing is perfect, but the clean air act and california air quality control efforts have achieved a great success.

dasubergeek - 1-24-2014 at 10:59 AM

We're wandering from the point. The gas in Baja is fine, especially Baja Norte, where it comes from the U.S. anyway. I have filled tanks on multiple vehicles many, many, many times and have never noticed any abnormal dirtying of the fuel filter or any such nonsense.

If you fill up in Baja, know that certain stations are well known for shorting the litres and playing games with the change. (The old "don't reset the meter to zero" trick doesn't work anymore, because all the new pumps automatically reset when the pump is taken off the cradle.)

If you get excellent service it's usual to tip a small amount, usually by ordering 480 pesos of gas and handing over 500 pesos or something like that.

Bravo-Yes I do remember. Growing up in Alhambra I thought wheezing was a normal childhood experience:biggrin:

Agreed, Mexican fuel may be better for your engine (that is subject to debate) and your finances, but California fuel is definitely better for the environment and your health.

Probably true, but in the global view, the requirement to include corn ethanol in gasoline, has a number of side effects.


As noted, Pemex uses MTBE - which is an Oxygenate - and is semi-indicative of Pemex taking similar actions intending to aid clean air quality.

If they're not smog-checking the vehicles, though, well...

And MTBE as well, has it's own environmental issues - perhaps even worse than Ethanol. Who knows?

Kudos dasubergeek your answer by far is the most accurate. 13.82 Magna, 13.88 Diesel, and 14.05 Premium may be cheap to you but it is playing hell with the family income and transportation prices down here. Yeah. Cheap Two hundred dollars for a ONE WAY bus ticket from Cabo San Locos to the border.

Baja California fuel is USA made, every last gosh darnned drop of it.

Baja California SUR fuel comes across in barges to Pichilingue. A tiny bit of the MAGNA may be a mix of USA fuel. All of the diesel is made in Mexico and all of the UBA premium is made in the USA.

David K - 1-24-2014 at 03:12 PM

Burning MORE gas than less is NOT better. Ethanol (corn) is causing you to combust MORE fuel for less results with harmful effects... all is not good for the environment.

A lot of other actions have taken place since the 1960's to lower pollution, and ethanol wasn't one of them. Have you forgotten all gas had lead in it before the 1970's (except Coleman white gas ... white gas is uncolored and unleaded). Getting more miles per gallon/ burning less gas is a big help. Ethanol is a filler and provides government bucks (our taxed money) to farms instead of farms growing food and grain.
