Blue DEF versus Blue Platinum DEF

Sorry if this has been asked before as I couldn't find anything on it after looking through 8 pages. What's the big difference between the Peak Blue DEF and the Peak Blue Platinum DEF? Can you mix the two DEF's? I guess you could run the DEF tank real low before filling it with the Platinum stuff. Is it worth it?

Thanks.

Looking around the internet I can't find anything explaining the difference. Just some guy in a shrinking lab coat that claims it keeps the catalyst cleaner. My question is how, when the DEF is only sprayed in when called for. So, there is no way it keeps it cleaner. It may or may not clean better when it's sprayed into the system, but that's not the words they use.

We buy our DEF in 55 gallon containers, and use quite a bit of it per week.

The only difference I can find between Blue DEF and Blue Platinum, is about $7.00.

People who use premium DEF care about their trucks. It speaks to their character and an elite standout in humanity. People who use regular DEF probably drink out of the toilet like a dog.

The Platinum DEF is supposed to reduce the build up of deposits in the SCR system. I think it's more effective in cold climates.

well, I guess I’m a toilet bowl licker… as someone else said, can’t find any difference other than the price. I do care about my truck, I’m one of the dopes who uses fuel additives year round. With DEF though, i don’t see any benefit to the higher dollar crap.

As long as you flush a couple times, the water isn't bad.

I was under the impression that you can't have anything added or removed or it isn't DEF. I assume it's more about the purity of the water and the urea compared to the spec, and most likely the Urea as the water isn't what's leaving the chunky residue everywhere.

the platinum def is advertised as containing a secret sauce that prevents build up of some unknown substance within the SCR.

They use de ionized water not distilled water.

According to the chemical makeup in the MSDS, the only difference is marketing hype.

I know de-ionized isn't necessarily 100% pure, maybe it's RO + de-ionized + distilled for the premium DEF

lets break this down, RO filter it to get 99% pure water, then run it through a softener that de ionizes it and removes any remaining hard water metals ions, then boil it and condense the steam to make again 99.99% water.
WOW , am i being a smart *** in regards to the company?
RO water is considered more pure than most bottled DI water we can buy off the shelf for 90 cents a gallon.

i think the marketing hype is thick in the area of how peak is marketing the def. yes it does covert gasses to nitrogen and water.
i use the regular blue def or motorcraft.

pre DEF, we still had issues with dpf ash build up,
fact remains the DPF continually builds up ASH that can only be removed through mechanical means or a chemical wash with the dpf removed from the vehicle, they(engineers) should be focusing on ash removal events, or some sort of other fluid in the def that possibly help remove ash build up.

There must be a huge SCR failure problem
for a company to make claims their poduct keeps the SCR cleaner than the other brand. Or maybe it's just marketing fluff and uninformed consumers fall for it?

We see DPF failures here in the forums but how many SCR failures? I can't think of any.

There are a few. It doesn't seem common, but it has happened where the pump fails. Whether it's DPF, SCR, CP4 or anything else. all that goes around here is anecdotal. Nobody but Ford has the data. I know there are some who believe the sky is falling every time someone comes here and reports a problem. That's fine. We can chose to reject or accept expressions of mechanical anxiety. Diesels aren't for everyone. I am fearless in driving my truck. It's doing just fine. I don't use additives. I buy fuel from my local Walmart. I don't check for water in the fuel. I change oil once a year since I'm on the calendar schedule. I know; I'm going to get what's coming to me. But I'll deal with it when it comes to me. Until then, Don't Worry, Be Happy.
