Walmart DEF Just Water

[kthaxton]

I am responsible for large deionization systems at my work. DI water has quite a range of purity level and can still be considered Deionized. Further, bacteria can exist in it and be undetectable by traditional means of measurement (resistivity).

Any evaporation process using distilled water (like a humidifier) that leaves traces of mineral, is likely from what the water mist absorbed from the air.

For all intents and purposes however, higher purity DI water is as good as distilled and can usually be used interchangeably, but as mentioned above, not a good idea to drink because bacteria can exist in it.

Economics is likely the only reason to use DI water in a manufacturing process (i.e. DEF) vs. distilled.

In the end, they are merely two different methods to achieve a similar level of purity, distilled is just more reliable in its purity.

Went into a T/A truck stop . bought fuel went to buy def at the pump no DEF . They wanted $32 for a box of peak . That worked out to about$16 per gal . I went on down the road and got it a another truck stop at the pump for $4.27 . $ 16 a gallon !! not including tax for water and pig piss . Crazy !!

For me the nearest truck stop to get Def from is a 40 minute drive on a good day, no way will I drive that long or far to get it so get it from Kroger, I have been told by Ram to not use that Blue Def brand, to use truck stop def or buy from them as the blue def is weak

DEF has to spec at 32.5%. Whenever I use Blue DEF it tests at 33%. So does Walmart's. DEF is DEF

I find it hard to believe “RAM” singled out a specific brand.

Ok it was a person from service dept, to me its all the same as the preach what FCA tells them too...

I had a service person tell me to only use Mopar because it smells stronger than the others.
Urea is urea and a mixture of 32.5% urea and 67.5% deionized water = DEF. You can't argue about that.

 

[Ozymandias]

So it is, DEF is DEF is DEF.... there is no such thing as better or worse.
Like said, it's urea and water and nothing else is allowed to into this mixture, the specs are tight.
Like ATF+4, if that label is on it it has to be 100% that - and not 99% or so. So is DEF.

Agree, but the one exception might be Blue Platinum. I believe it has a proprietary additive that owners are reporting keeps the injector clean of deposits

28$ a 2.5 box in my area Auto Zone. I bought a box

That additive must be made of gold or something, standard DEF is around $15.00 per 2.5 gallon box less when on sale

 

[Ozymandias]

Well then it wouldn't be legal to label it DEF. I just checked the ISO standard for DEF and the licensing programm from the API and it is absolutely clear, there is water and urea and nothing else.

I'm going to check that Blue stuff now...

 

[Ozymandias]

It is weird, the more I read the more I see it is only water and urea.

Even the SDS states the ingredients as water and urea and nothing else, and that document has to be correct - right?

You may need to re-research. Old World Industries is able to label their Platinum as DEF. Here's what they say about their Platinum DEF.

"BlueDEF PLATINUM™ with Advanced SYSTEM SHIELD™ Technology is a groundbreaking premium Diesel Exhaust Fluid with a proprietary formula to tackle deposits that can build up in the SCR system. Through continual use, BlueDEF PLATINUM with Advance SYSTEM SHIELD™ Technology reduces future deposits that build up in your diesel exhaust system."

That's funny since the SDS for BlueDEF Platinum says, water 67-68% by volume, urea 32-33% by volume. No mention of anything else on the SDS. If there was, it would have to have a listing percentage by volume. Wouldn't have to identify, but would have to list it. So DEF is DEF no matter who makes it. By their SDS, there's no volume left for any additive. Sounds a bit like "SMOKE and MIRRORS" to me. Been using Supper Tech and Travelers without nary an issue. This is starting to sound like the oil filter debate!

So - based on the SDS is Platinum all Marketing hype, a scam, or a lie? A mystery?

Time for an X-Files investigation I guess. Could be all of the above! Can't see spending the extra $ with how many millions of miles driven with plain ol' DEF. Maybe there's a chemical engineer that someone knows and they can shed some light.

 

[Ozymandias]

It is also not Prop.65 labeled, I think there is no chemical ingredient aside from water and urea that would not need that label. So yeah, it's a mystery.

"Advanced SYSTEM SHIELD™ Technology" probably means they filter the water somehow to remove some/most of the minerals that could cause clogging. I think the keyword is "technology".

Good call, that could be the answer
