Super Tech Def VS Blue Def

[colenighthawk]

Has any of you used the cheap brand from Walmart?

 

[boatpi]

I’ve been using it for four years in three different diesels never had one issue

 

[Ace in the Hole]

I buy my box DEF at Costco but since 2020 it’s went from 8.99 to like 14, but it’s over 20 at parts stores etc

I’ve used the Walmart and loves truck
Stop brand as well with no issue

 

[Mikes56]

I’ve used it in my 2016 Duramax, haven’t had a problem.

Terrified to use anything except Platinum BluDef. - am I just being stupid/paranoid/ocd? First diesel, cummings ibs6.7 in a 33’ pusher. $24 each @ AutoZone. Guys, set
me straight please

Cummins…

Yea I saw that stuff at $10 more a jug.. for a motorhome I’d be buying it at the truckstop pump…wasting money.

 

[WhatExit?]

How different can the truck pee be? I’d expect them all to meet some standards that automakers set for the stuff. Can one type of urea be any better than others and would the truck “know?”

From Wikipedia:
Diesel exhaust fluid (DEF; also known as AUS 32and marketed as AdBlue[3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous ureasolution made with 32.5% urea and 67.5% deionized water. DEF is consumed in a selective catalytic reduction (SCR) that lowers the concentration of nitrogen oxides (NO
x) in the diesel exhaustemissions from a diesel engine.

2016 Cummins. I either use the truck stop pump or the Blue DEF. I feel like the platinum version is a scam.

182k on the clock with no issues.

 

[Icky]

I won't def buy from Walmart, there was stories about people refilling it with water and returning them years back.

Ok, 2 weeks ago I was playing "Operation" with an ISB. Truck shows 125k, but PTO equipment has clocked 13k hours on it.

With the scanner, checking all the smog doohickies, I ran across the "DEF Consumption". It's run through 378 gallons of DEF since the new system. (New system was installed due to operator sabotage...gas in DEF tank) Since new, that truck has run AutoZone DEF. They run a sale about twice a year, and the owner of the trucks buys a couple pallets for his ISB trucks.

The DEF system has a sensor that basically checks the concentration level in the system. I believe it's 36%? If it doesn't have that, the ECU will trip a light.

These systems are terrible and have caused so many nothing but headaches. After a seemingly endless def tank heater issue, i think it all fell off my truck at some point hitting a pothole and never had an issue since.

Still have an audi tdi in the fleet and that just spent a month at the dealer getting new everything…def injector, tank, heater, particulate filter. (Under Warranty). The injector stuck open and it was blowing it out of the exhaust pipes. Pretty impressive really…..

Having said that, i use nothing but adblue in the audi except one time. That resulted in a check engine light for a clogged injector and a no start warning in 100 miles 90 miles from home lol

Cheapest place i get adblue from is the bmw dealership

So you think the thieves only theive from Walmart??

You guys are all spazzing about nothing. The answer is right here, and it is injected AFTER combustion. Your “engine” never sees it. If there are no codes, you are golden. Cheapest stuff you can get is the same as Wham Bam Thank You Ma’am.

 

[Icky]

Yes lol, I don't shop at Walmart in general

 

[rivermobster]

Yes lol, I don't shop at Walmart in general

I'm kinda the same.

 

[Bajastu]

With my F250 I use whatever the fuel company fills the tanks with at work. We burn through it so fast at work with all of the heavy equipment, it’s always fresh.

 

[fastestbowtie]

I used to use the Blue Def from Sams before the price went up years ago. Since then I have either been using the DEF from the pump at Buccees or buying their brand from inside in 2 gallon jugs. The spouts arent as nice as the ones with the Blue DEF, but that is the only difference I have seen.

 

[boatpi]

Always pull the cap to make sure the seal is intact. I have even found Simple Green jugs filled with water, these assholes buy it, empty it at home , refill and return. Dopes at the store do not check. I found one SG at Home Depot 2 years ago, so check. Never any issues from 2 trucks and a Range Rover, all never had any DEF issues.

 

[Mcob25rg]

Thanks for the input and education. I know you guys know the facts!!

 

[OCMerrill]

DEF seems to be the latest scheme to rip folks off. I've been buying this at Summit for nearly 4 years.
Perhaps I can drink a case of beer, get some car wash spot free rinse tanks and make my own.

Used to be two, 2.5 gallon jugs for $42 shipped. Now the same thing does not ship free and would cost $76 shipped.
So now I make the decision to just find the cheapest possible thing or what?
I'm not paying $75 bucks for 5 gallons of 35% Syn Piss and the rest deionized water.

Not sure about truck manufacturers but I used to work at a deere dealer and we had test kits for DEF and if you were found to be using anything other than the deere brand DEF you're warranty is no more....I have a new deere tractor and run the blue DEF unless I have rewards points to use at the dealer....if I remember right even with my employee discount there the blue was still cheaper...I wouldn't see an issue running the walmart brand unless it is older than dirt which there should be a manufacture date on the case. Also check the urea concentration....as long as it's the same as the blue run it...that's all that really matters in that crap....tractors are a little spoiled in that if you work them hard enough you don't use much DEF vs a truck but I have fixed my fair share of DEF issues and it usually boils down to either contamination in the tank or a faulty sensor due to the cap being left loose and the tank turning into a solid crystalized rock inside lol

 

[J DUNN]

I buy it in 55's from Nickey Petroleum in Anaheim. I think it's $5 a gallon right now. Actually bought them out of stock a year ago and bought 5 drums. We are on our last one and it still works fine with no issues. We have 3 diesel box trucks and 4 pickups that we use it in. Sure beats buying it at the store, not to mention the wasted labor of my employee stopping for fill up.

 

[Badchoices03]

I use whatever I find when I need it....didn't know I was supposed to be picky about it....lol

 

[Bowtiepower00]

I use the Wally World stuff all of the time in my ‘17 Cummins, and in my ‘16 Cummins without issue. It used to be 7 or 8 bucks for 2.5 gallons.

Now that DEF has gone through the roof and it’s always sold out, I try to fill at truck stops from the pump.

We have a fleet of over 800 units and 133 are John Deere, we use non-Deere branded DEF. We have no warranty issues using another brand. Dealer warranty cannot dictate what brand oil or DEF used. As long as it meets the required specs, you are good to go. The Magnunson-Moss Warranty Act of 1975 did away with dealers requireing that you use delaer only parts, lubricants, etc...

 

[EmpirE231]

I have a 2.5 gal sealed jug in my garage that's been sitting for about 10 months.... would you use it, or toss it out?

If you have a newer truck (‘19ish and newer) and it’s been exposed to 100+ degrees for a few of those months, I’d give it to someone with an older rig that’s not as sensitive to bad DEF. The 18- older Cummins trucks will run on the older stuff without issue, from my experience.

Unless JD is making their brand of DEF available free of charge, what they're doing is against the law.

 

[BBYSTWY]

That's very interesting...I have personally seen them deny a warranty claim on a transmission due to the "wrong/non deere hydraulic fluid" being used. Possibly they can get around it in that instance by saying it's "the wrong fluid" however....in the manual to all of their products it states to use their Hy-gard or equivalent with the specs...how they determine it's not to their specs is beyond me...I just turned the wrenches I didn't make those calls hahaha.....glad not to be there anymore anyway....great product but a LOT of big business politics at the dealer level....

Anyway back to the DEF.....I'd say don't overthink it....if it's old and doesn't burn your nose when you open it....buy new of whatever brand you choose....that's my opinion lol

 

[BBYSTWY]

FYI not saying any of you are wrong on that being illegal! Just saying it's interesting to know that!

Working at a CAT dealer for 16 years I saw the same thing. The typical dealership mentality is to always have the manufacture’s back. Realistically, the dealer made out either way when the component failed and was rebuilt. The manufacture or the client is paying the bill, not the dealer. Customers make a dealer successful, not the manufacture. I was the guy who would tell them to fight warranty claims and walk them through the process to be sucessful. The only real standard with warranty was oil type, service intervals, and oil sampling. Outside of these parameters a failure was a failure as long as there wasn’t customer abuse or used in the wrong application. We go head to head with CAT & John Deere dealers all of the time and 90% of the time, we come out on top.

They can deny if it doesnt met spec but not that it wasnt deere brand. If the def didnt meet the urea % or the trans fluid was the wrong type that is a different story.
