DEF for newer diesel trucks

Has anyone seen this for sale anywhere?
Last I checked, not at Walmart, Autozone or Orma auto parts.
Thank you.

Found this company in MX; NOW all you have to do is find a distributor.

Have you checked any of the Pemex's that sell diesel fuel?

OK I admit I am dumb. What the hell or heck is DEF?

Going to Google didn't help much.

Here is one of the definitions given by Mr. Google


def abbreviation

Medical Definition of def

1 defecation

2 deficient

3 definite

It get's even crazier as I dig deeper :)

DEF, MOS DEF. An entertainer, or something.

Diesel Exhaust Fluid. It is a government mandated additive to reduce diesel emission's. Pretty much any diesel powered vehicle produced for Canada or the USA after 2010 or 11 require it.

Thanks Bob for the definition.
I inquired at every fill-up from the border to here, but none of the stations even knew what it was.
I looked at the link posted above but no mention of distribution so I sent them an email. Fingers crossed.....

Yeah, I don't think Mexico has mandated it's use yet hence the reason it is hard to find.

Most (all?) newer diesel vehicles will throw up a lot of warnings if the DEF tank starts getting low. Some will actually NOT start after the vehicle’s DEF tank is empty. Others will reduce the vehicle’s speed to 5-10 mph until the DEF tank is filled back up.
YMMV

The problem is that these newer diesel engines are meant to run on the less polluting, ultra-low sulfur fuel which is not widely available in MX. Their "dirtier" diesel fuel mucks up the engine much faster, hence, more DEF is used here. Still can't find it.....

Have you asked the dealerships here that sell those vehicles? Checked Amazon? Asked Felipe at the taller next to Telecable?

I think the Mexican diesel vehicle's don't require the DEF.....yet. I would talk with some of the large Mexican trucking companies who transport all the way into the USA and Canada. I suspect they would have to meet the emission standards up there.

The diesels engines made in MX for the MX market are different. They are not as clean, and do not require ultra low-sulfur fuel or DEF. And other than some border towns and CDMX, there isn't much of that fuel. Even the fleet Mercedes Sprinters vans (DHL, Estafeta, UPS, Jumex) don't use/need the low-sulfur or DEF.

Good idea to check with the big international haulers. You would think they would be required to follow the current regs, maybe not.

They, the Mexican truckers, drop their trailers just beyond the border, where they are picked up by US trucks. Then, the Mexican trucks hook up to southbound trailers.

Autozone in front of Walmart now carries DEF.

Excellent. I will make a note of that for future requests. Thanks for reporting back.

OK call me crazy but been told by a fellow Teamster/Dreamster just now that the major component of the DEF formula is pig urine (uric acid). This conjures up a lot of images of the necessary accumulation.
it appears the onboard computer decides when to inject this shit to clean out the pipes, so to speak. This explains why a newer deisel truck will suddenly beltch black dreck for 5 seconds or so. Isn't that swell.
So, please be mindful when peeing into that hole .

Oh, more urban rumors....

"DEF fluid is composed of Urea and deionized water. Pig urine (or cow, horse, even human) is largely urea and many people refer to DEF as pig urine even though the majority of DEF on the market is not made using animal byproducts. Regardless, the name has stuck."
