Blue Def vs Blue Def Platinum

[joshthedoc]

I've learned something very important today. As Jrod250 has demonstrated in the above post, one must NEVER UNDER ANY CIRCUMSTANCES squander an opportunity for a "jugs" joke. Oh yeah, and what they said about DEF.....

Why buy cat piss, when you can pee in a bottle or collect cat piss????

Because it's not piss, it's urea and water

Just saw the new Platinum Blue Def. Just marketing hype or is there a difference?

I have a 2016 F550 PowerStroke. It appears I am getting slightly better fuel economy in it running the platinum versus the regular. The FRAM DEF and the Peak DEF are both made by the same company. DEF fluid has an expiration date, too, so it is NOT worth it to "stock up" when you see a low price. The shelf life runs no more than two years. The date of manufacture is dot-matrix printed on the side of the cardboard box. I have no comparison to DEF at the pump. As far as I can tell, there is only one station in New Hampshire that offers DEF at the pump and it is a fair distance from me. Finally, I work part-time at a national chain auto parts store and several customers have reported their exhaust self-cleaning cycle does not engage as frequently when running the platinum product. I also had one customer that bought four 2.5 gallon containers of DEF. I reminded him of the expiration date. He indicated his rig (a Duramax diesel) went through that much in a short period of time. His truck was not that old. He did not idle a lot. If you are going through a LOT of DEF in a short period of time, something is wrong. Not sure platinum will help, but it might not hurt to try.

Ok, now you have to explain how one DEF can possibly improve fuel economy over another. I can't see how something that is injected downstream in the exhaust can have any effect on MPG.

Also just to add another, Napa DEF is made by the same company as the PEAK Blue.

And? I'm sure you are aware that DEF and regen cycles are completely unrelated (sort of), one type would have to reduce soot load in the DPF more than another, I don't think even PEAK makes that claim.....so, I am still waiting for an educated answer on how one DEF can produce better MPG over another.

Edit: All I have been able to find is that the Platinum supposedly helps control build up in the SCR that could potentially cause increased back pressure and reduced fuel efficiency. That build up would be a gradual process, and they don't claim that the Platinum removes existing build up, just controls future build up. I still can't see how simply going from standard DEF to Platinum would give a noticeable change to MPG.

Free-breathing exhaust in general will help with fuel economy. I have not done a scientific study that would pass university muster. The only way I could *prove* there is an improvement would be to have two *identical* trucks running identical fuel, with the only variable being one truck running regular DEF and one running platinum - side-by-side - displaying the instantaneous fuel economy and see which reads higher. I am open to alternative ways to prove a difference - or lack thereof.

it's all just piss and water.

 

[HeavyAssault]

Given I'm now at that point to add "DEF" I'll give it a try. The hardest part will be a baseline eval on MPGs but hey if it works I might notice the MPGs going up.

 

[FordFanStan]

All DEF is standardized per ISO 22241 to 32.5% pharmaceutical grade urea and 67.5% deionized water.

There is a difference between regular blue DEF and the platinum version. It was discussed in a thread late last year: https://www.fordtremor.com/threads/def-fluid.13293/post-271570

 

[HeavyAssault]

So far I've gained 25HP/100TQ...way too early to see MPG results....WOOHOO!!

There was this comment in the link above:

Could all be really great marketing, and at 33% more expensive that definitely adds up given you're using about 3 gallons of DEF for every 1K miles.

I just drove about 5500 miles....I used 5 gallons of DEF. So I'm not sure where or how that math was done to get to 3 gallons for every 1K miles. Maybe they just hit the mall and grocery???

What year is your truck? My '22s Def miles says 9500 til empty. Even towing it barely uses it. I'm at 12k miles and have added 2 jugs since new. I wanted to burn it to empty this time because the Def is almost a year old from Ford.
Def is Def, just like diesel is diesel... I guess they could label a diesel pump premium diesel and charge 40% more and some guys would fall for it.

 

[HeavyAssault]

2022 here. Yes, the DEF now shows 9500 miles to empty. I'll clarify: I added 2 jugs to bring the DEF to full. DEF level was over 1/4 left at the time I added the 5 gallons of DEF. If you think of the DEF tank in 1/3's it's one DEF jug to every 1/3.

Diesel fuel does have different cetane ratings just like you would see with gasoline octane ratings. So diesel isn't diesel...Not to mention you MIGHT find stations that sell biodiesel B10/B20 out the pump. Unless you read the stickers you would never know.

 

[HeavyAssault]

If you live in an area you can try higher cetane diesel yourself. No different than adding a bottle of diesel fuel additive, it's already done for you. For one area I frequent there are stations available.

50 Cetane Diesel | Southern States Co-op

SuperGold premium diesel fuel has special additives proven to be more powerful, cleaner burning and economical in comparison to generic diesel fuel.

My point is that b20 or diesel number 2 isn't a different price like the 2 versions of Def.... and there isn't 2 pumps to choose from, the cetane isn't advertised. You really have no idea what you are pumping in your truck... At least where I live.

 

[HeavyAssault]

Most "bio diesel /bio blend" pumps are required to state that on the pumps. As well as most pumps generally show the 40 cetane rating for D2.

 

[StrokinOut]

California has a minimum cetane rating of 53, and the renewable diesel "Rxx" claims even higher. Niether post the actual number on the pump. There are requirements for labeling depending on what it is. Diesel (including Renewable) with more than 5% Biodiesel can't be labeled #2, and has to have a Bx. That's in addition to the small sticker noting the percentage of biomass based or biodiesel.
