Back in the day - around '96 Mexican diesel was in my opinion far superior to US diesel - more power, better mileage. It even looked different - not clear and watery like US diesel but more opaque and a yellowish color.


You don't have to go back that far. Mexican diesel, LSD, is better than USA ULSD TODAY. The stuff pumped in the USA is ****.

I get 20% better mileage, more power, and a quiet running engine when in MX vs when driving in the USA.

How can burning 20% more fuel to go the same distance be good for the environment?

At one time the Mexican fuel had a higher Cetane than in the USA. Our previous Blue bird would act like a race car on Pemex fuel. I think it is still better but not as good as say in 2008. I never really noticed a mileage improvement.

From Ed White:

Good Morning Paul,

I haven't checked lately, but Chevron Mexico's website used to carry the message that their diesel fuel is DUBA. (Note Arco is all DUBA)

In any case, at this stage:

1.
Nobody has reported to me a single verifiable case of sulfur-in-fuel problems since April of 2018.

2.
The three or four third party reports I have received related to emissions light warnings over the past 18 months have all resolved themselves, except for one, which suggests that fuel was not the issue. In the case which did not resolve itself, I managed to communicate with the owner. The problem turned out to be a faulty NOX sensor.

3.
Diesel Exhaust Fluid (DEF) was first introduced NINE YEARS AGO, and those nine year old trucks are beginning to experience NOX sensor failures and intermittent misbehavior simply due to aging, not the fuel. So, it would be helpful to note the model year of vehicles exhibiting emissions system warnings when trying to determine what caused the problem. The older the truck, the more likely it is a component failure.

4.
The lack of proven fuel related problems since April of 2018 suggests to me that Pemex is diverting most or all of it's LSD to shipping, electrical plants, and bulk purchase industrial customers, not the retail automotive segment of their market.

5.
The entire Baja appears to be continuing to receive exclusively DUBA. There are a LOT of Snowbirds down here with late model diesels, including me, and there is no sign of any issues. The last samples I took, admittedly a year ago, were DUBA for both northern and southern Baja.

6.
One way to determine whether a station is receiving DUBA is to get a look at the delivery manifest documentation, if they will show it to you. The document WILL list the diesel type delivered on the last top up.

Regards
Ted

I will avoid those stations like Arco that are pumping ULSD. What other stations guarantee pumping ULSD? Should I just stick to Pemex?

Is there off-road diesel (red dyed) available in Mexico that I can pump into my truck?

Ed White should tell us the rest of the story. Pemex is having trouble importing ULSD as Amlo is insisting they must sell Mexican fuel. But no refinery in Mexico can produce enough ( or maybe any) ULSD. But ARCO and a few other independents can import ULSD fuel. I have to eonder if Ed read the first posr with a link. Pemrx is not allowed to import ulsd inmost states. Period

Can you provide a link to anything that verifies this statement?

The link is in the first post
It lists the states where ulsd will be sold by Pemex. Amlo had to change the date for availability as they cannot produce very much. Amlo is upset as they lose money on imported fuel. He is battling with Pemex.

It seems that Mexican diesel is no longer high cetane. The signs say 45 cetane
That is the same as US fuel.

CRE (The Regulatory Energy Commission)Ex........ine For Pemex To Reduce Sulfur In Diesel

The article is in Spanish.

Again, our messiah president has delayed another action until he completes his term in 2025 so that he is free of any criticism. His CRE, which has no energy expert on the board (remember my earlier post about the CRE board selection where the winning candidate was asked what a cell was, referring to solar energy and he raised his cellphone in the air) has agreed to his decision. Our president is determined to undermine any previous decision made by any previous administration.

In some bizarre way, one would get the impression that there is a plot against North America based on the three leaders involved and the decision they are making.

Well, I'm not too sure that states anywhere that "Pemex is not allowed to import ULSD in most states. Period." It does state that "Pemex can continue marketing ULSD only in Mexico City, Guadalajara, Monterrey - Mexico’s three largest cities - and on the northern border". it THEN GOES ON TO STATE THAT "In the rest of Mexico, companies may choose which type of diesel they will offer."

One could (and should) easily read the statement as meaning Pemex will continue marketing ULSD ONLY (as in No LSD allowed) in Mexico City etc, as has been the practice for several years now.
