Changed sig to another pic

 

They do but the Kenworth Truck dealer behind Donna's has it as well. It is bulk and I have had no issues. They pump it. My Diesil comes from the Union 76 at Island Crossing West side of exit 208.

 

Donna's wont let you go back with a pickup, have to be a Semi. I bought 1 there to get rid of the alarms. I should have gotten two now that I read more. It says less than 1/2 now, Ill pick up some at Wally world tomorrow.

 

Have to give my two cents worth here. The last two time that I had to add DPF fluid, I chose the "cheap" Walmart stuff. Immediately after the second time, I got the p270f code with an engine light. Reductant fluid Quality, speed restricted to 50 MPH. 375 bucks later, the Mechanic told me that they had to drain and clean the tank due to bad DPF.. Asked them what that meant, and then asked me if I'd used an off brand such as Walmart? Guilty. Seems that you CAN put in bad dpf fluid. Buyer beware. Save 7 or 8 bucks and get a bill for 300 to 400. Might be coincidence, but I'll pay the 17 bucks for Peak Blue Or good stuff from a truck stop from now on.

 

Was the DEF jug from Wal Mart sealed? BTW, the code is P207F.

I have used Wal Mart DEF with no issues. I have only used Wal Mart DEF for the last 3 years.

I have even used DEF of another brand that was over 4 years old and had been stored in my truck tool box with no issues. I live in the South where temps during the summer are 90's or higher.

Others on here have used Wal Mart DEF with no problems. You might have obtained a "tainted" jug that wasn't sealed and/or a returned jug that wasn't DEF. You are welcome to buy your DEF of any brand with your money.

 

As I said in my original post, I was just giving my two cents worth.. The plain jug was properly sealed (both of them). Maybe it was coincidence, but it sure isn't worth my tanking another chance.

 

this is a a 5 year old thread and was hashed out extensively on this one and others. Maybe a new thread would have been better for it than re-opening this one. Just as you have your preferences, others only want to use the truck stop diesel DEF pumps and i, along with others have no problem with the $7.88 jug of DEF from Wal Mart..

 

x2 on the Wally World DEF. I have not had a problem with it. I've used the 2.5 gallon Motorcraft bottle early on and have bought it from Advance Auto. But have been using the HiTech DEF exclusively. I'd just like to know what "bad DEF" is and what it means. Does urea go bad or does it mean contamination? As long as the DEF meets the specs, why does it have to be bought at the dealership? That's the same thing as saying you have to use Motorcraft oil only.

 

Got a place called Atwoods down home that has DEF, usually have a no-name brand for about $5.99 for 2.5 gallons, it's what I buy if I can't find a truck stop that has it, which I haven't been able to that's worth the drive to locally, so it's what I use, or Supertech DEF for whatever Walmart sells it for, I have had zero issues. I do not buy into the dealership only, etc. stuff. It's a scam, DEF is DEF

 

I guess everyone misunderstood my post. (realize its 5 years old). I was just making a comment. The Mechanic both at ford and the private shop I went to both told me that some dpf fluid if left for a long time can cake and clock up the tank. I've actually seen the small chucks when overspilled on the filler neck. Anyway, I wasn't bad mouthing the Walmart brand. The stuff I got at Walmart was in a plain jug and was NOT supertech or or Peak. Not sure what it was. I just won't buy it again. I've never bought from a dealer , but always from Walmart, or advanced Autoi, with one or 2 at a truck stop.
Again, I wasn't trying to start a big discussion on the merrits of one brand or another. Was just passing on my experience.

 

And people were sharing their experiences.

DEF will crystallize when it left so that the solvent (water in this case) evaporates. The crystals will dissolve when put back into solution. This is evident when you spill DEF and then wash it off with water without scrubbing.

As I stated earlier, I have used DEF that was over 4 years old with no problems it was not stored in a cool dry place. It was in my truck tool box for the 4 years. I have also used DEF that had previously been opened for over a year with over half being used from the container and stored on my shelf at home with no issues.

Why yours "caked" or "clogged" should probably be investigated so it doesn't happen again.

 

I don't doubt your experience, but I personally have not seen anything other than Supertech and Peak brands at Walmart.

 

Okay, this made me curious so I did a little digging on DEF fluid. As usual, I overkilled this... Here goes:

American Petroleum Institute

The American Petroleum Institute (API) runs a voluntary program for certifying DEF producers and distributors through its Diesel Exhaust Fluid Certification Program. Suppliers who have been approved by the API display its logo on their DEF products, guaranteeing the quality of your purchase and its suitability for proper SCR operation. API takes random samples in the market to ensure DEF quality.

All DEF marketers listed on www.discoverDEF.com are API certified.

"ISO standard

The production, handling and transportation of Diesel Exhaust Fluid (DEF) are governed by the ISO 22241 standard. The standard covers five main points:

1. Urea concentration: DEF must have a urea concentration of 32.5% by weight. This concentration was selected because it is has the lowest freezing temperature, 12°F (-11°C).
2. Contamination: Contaminated fluid can damage SCR injectors and catalysts, resulting in system malfunction or failure. Therefore, the maximum level of impurities permitted in DEF, such as calcium and various metals such as iron, copper, zinc and aluminum, are clearly specified. There limits are set very low. For example, a spoon of table salt in a DEF tote would push the sodium content far above the ISO 22241 limit of 0.5 ppm.
3. Quality: ISO 22241 excludes the use of urea granules used as fertilizer in agriculture, and requires water purified by distillation or de-ionization.
4. Materials: Only certain materials are permitted for the storage and handling of DEF. DEF is corrosive to many materials, including carbon steel, copper and aluminum, which cannot be used. The main risk of using incorrect materials with DEF is that the DEF will be contaminated by the material, resulting in damage or failure of the SCR system on your truck.
5. Handling guidelines: Guidelines require manufacturers to follow clear procedures for the manufacture and distribution of DEF, ensuring that the product you use meets the the requirements of vehicle manufacturers."

How DEF brands differ

It can be frustrating to pick the right DEF for your vehicle. All diesel exhaust fluid must have a urea concentration of 32.5%, so how different can the brands be?

• Impurities: To meet EPA standards, DEF must contain a limited percentage of impurities such as iron, zinc, and aluminum. These impurities can enter the DEF if the manufacturer uses poor-quality deionized water, for example. Too many impurities in the DEF could cause the SCR system to fail prematurely. A cheaper brand of DEF might be at the edges of the impurity limits, while a more expensive DEF might have many fewer impurities than required by the EPA.
  
• Urea: An approved brand of DEF must use pharmaceutical-grade urea rather than agricultural-grade urea, which might have impurities like biuret in higher levels than higher-quality urea.
  
• EPA standards: To call itself diesel exhaust fluid, the product must meet all EPA standards, especially ISO 22241. If you find a cheap product that claims to be diesel exhaust fluid, but it doesn’t meet ISO 22241 standards, don’t purchase it. Such a fluid could damage your vehicle’s SCR system.
  
• Manufacturer recommended: When looking for a brand of DEF to purchase, check your vehicle owner’s manual. It might recommend a particular brand, and you should follow this recommendation. If you don’t have a manufacturer recommendation, only select a product that meets ISO 22241 standards to protect your SCR system.

So I guess it is possible to get contaminated DEF fluid...

 

No one has disputed that one can acquire contaminated DEF. He states he bought a white container of DEF from Wal Mart, not Peak nor the Super Tech blue container of DEF.

 

I was just typing what i was thinking, that's all. I, myself, did not realize you can buy contaminated DEF. More of a learning point for me. I just posted up the links I saw in case any one wanted to read them.
