PEAK Blue DEF Platinum: Any Issues?

[Goose55]

I purchased a 2.5 gal box of this at Walmart and checked some reviews. I haven't used it yet. Anyone here have any experiences with it?

 

[crash68]

On another forum for diesel pickups, some of the members give it the thumbs up where as other can't justify paying extra for the Premium version.
Usually the best source for DEF is a truck stop pump.

 

[Billet Bee]

For 3 years we paid the ever increasing high price on mopar def, then on our 4th year we switched to peak platinum and the truck is guzzling more def now because it's regenerating more. Other then that zero issues with truck, knock on wood

Diesel Exhaust Fluid (DEF) which is composed of 32.5 percent urea and 67.5 percent deionized water.

PEAK BLUE DEF Platinum.
Review on the PEAK website:

Do not buy this garbage. When you check it with a $30 refractometer you will find that it does NOT comply with advertised stated standards. It will throw your emissions system into a confused state and cost you dearly. Just go to the truck stop and fill it up

Platinum blue def fluid crystallized in def tank causing tank sensor issues. The tank ultimately read empty.
Required a decrystallization additive removing crystals.

DEF does nothing for regeneration or the frequency of when it happens. If the truck is regenerating more, that has something to do with engine or the DPF itself.
DEF is injected to the SCR which is after of the DPF.

I don't get why people don't understand this. DEF and regens aren't related really. But for some reason so many believe they are.

I can't speak for using Platinum, I have stuck with regular Blue because, after comparing the boxes, there doesn't seem to be any justification for using Platinum.

That said, it's hard to fill up at a pump when there aren't any nearby.

I've only been to one or two pumps that had DEF in 50K miles.
That said I have been using Walmart DEF when possible, with a few Blue DEFs thrown in when I couldn't get to a Walmart.

 

[nlambert182]

We have 2 local stations with DEF pumps, so I always filled up there any time possible. It's a lot more fresh.

That said... I never saw a reason to buy the more expensive one either. More importantly is the manufacture date than whether or not it's "platinum" or "regular".

 

[Scottly]

This proves that if you market it correctly, people will buy dog poop in a pretty pink wrapper. As to DEF, I buy the cheapest horse pee I can find. If it isn't old, the chances of it crystalizing are slim. THAT is why people recommend truck stop DEF....The truckers use a lot of it and it doesn't sit there long.

It's guzzling more DEF because you got a software update...After the guberment caught them cheating.

How much DEF you use is not determined by the brand of DEF whatsoever. It isn't injected until the computer tells it to be injected.

IF you had the emissions update from FCA, then that's likely why it's using more.

I buy the 8.88$ stuff from wallmart or the 9$ stuff from autozone.

When the truck goes into regen, does it use more fuel than when it’s not in regen?
If so, does this create more NOx than the amount that is created when not in regen?

 

[nlambert182]

Yes, it does. It injects fuel on the exhaust stroke, that fuel makes its way into the NoX canister to ignite and burn the crud out of the DPF. The NoX issue is mitigated by DEF injection.

It was a leading question for @2003F350, and @crash68 (not sure why it didn’t include his quote in my post) for their response to @Billet Bee when he said “the truck is guzzling more def now because it's regenerating more”.
That would be a true statement, but they responded as if he said “the truck is regenerating more because it’s guzzling more def now”.

The extra fuel used during regen is injected on the exhaust stroke with the purpose of burning in the DPF. That burning of the fuel isn't under the higher heat and pressure in the combustion chamber that produces the NOx. Some manufacturers resorted to a separate fuel injector just before the DPF for adding fuel for regen. Boost pressures are usually reduced also during regen to mitigate ideal conditions for regeneration which also help with NOx reduction.
More than likely the greater use of DEF of @Billet Bee truck is related to an engine, DPF or program change, not a different DEF fluid. Also the short window that a system is in regen compared to drive time, wouldn't make a noticable difference if DEF usage. Unless the vehicle is towing/heavy load, typically a gallon of DEF is used over about a thousand miles.
There's a whole other science involved of when to inject the fuel to reduce combustion noises and soot production.

Thank you, I was just sitting back listening to all those who are acting like there responding to me as if I'm the op when all I did was reply to his question and make an observation about what Id noticed switching from mopar to peak platinum. Been in the commercial regeneration game long before def ever got introduced into the process, so I understand how the systems operate

Just to clarify, are you ultimately saying that there isn’t any more NOx that passes through the SCR system during a regen than when not in regen?

All I use is Wally brand DEF in my 22, I have not had any problems using it...
