Stopped at a Sheetz today to fill my DEF. tank. Surprise. The pump nozzle doesn’t fit in our tank. What the **** was Ford thinking!

You are going to be wondering what you are thinking if you run anything other than motorcraft def fluid in this truck

Doesn't matter the brand of DEF, I fill mine up at the truckstop near my house. Pull up to a diesel truck pump and just use the DEF nozzle, much cheaper that way.

Brand of def makes no difference, just be sure to check the date on the package. If you can find it at a station with truck pumps, even better. Wish there was at least one near me.

The only thing to look out for on DEF fluid is if it's API certified, if it is, you are good to run it. All the major brands seem to be API certified.

Is this the first diesel for most of you all? Might want to ask your local diesel mechanics and service advisors about blue def and the regen system in Ford trucks many have had to be replaced bevause of it and the lubrication in usa diesel is not enough for our euro designed engines which is why many 5-8 thousand dollar fuel systems have to get replaced at 100 thousand miles or so

What are you talking about? The lubricity of diesel fuel has nothing to do with DEF. DEF doesn't go into your fuel system at any point... It's injected into the exhaust downstream of the DPF before the NOx cat. Is this your first diesel? lol. Completely separate systems and issues easily solved with a) Using API certified DEF, and b) adding a lubricity additive to your fuel.

Just a word to the wise.....I would recommend you consider the following:

Should your truck be under warranty, and an issue with your DEF system crops up, and you are using some off-brand DEF, it is possible you could be refused warranty especially if what you put in was old or contaminated.

By using and keeping your receipt for Motorcraft DEF purchases, preferably from the FORD dealer will eliminate the BS entirely. Why take a chance for a few bucks or convenience. Should an issue develop, using what FORD sells takes away the problem you will likely face when they deny warranty based on crappy DEF in your tank. Yes....DEF is basically all the same product, but it IS SENSITIVE to heat, age, storage temperature etc, and can crystallize quicker that you know what. For what it costs, get it from a dealer, and keep the receipts always. Just some optional friendly advice.....your experiences may vary.

LOL yes I know the diesel fuel and def are different issues, The blue DEF (peak I think) has destroyed many a Ford Power Stroke DEF system and I have a friend who just had to replace his entire fuel system from a fuel pump that went out. That repair alone was 8 grand thinking it would be somewhere around 6 grand for our trucks. He now uses Opti lube XPD in his truck and I bought something called Standyne. Just want the piece of mind that comes from using products designed for and to protect those costly systems.



He said the diesel mechanic told him that modern USA diesel fuels do not have the lubrication in them like euro market diesel and it will cause the fuel pumps to fail over time. It will dry them out and cause them to basically disintegrate in the tank thus leading to the entire fuel system to be replaced all lines, injectors, etc. You might have a different experience but this is what some of the diesel people have been telling me.

@jamanrr, like others have indicated, your comments are confusing. Fuel system and diesel exhaust fluid are separate conversations and mentioning fuel lubricity in this thread is misplaced.

Like several mentioned, get the cheapest API certified DEF fluid you can find. It's all the same. I checked Ford's manual and they mention ensuring it is 32.5% urea, 67.5% deionized water, which everything I see is. Again, as other knowledgable and seasoned members of this forum mentioned, I too buy the cheap stuff from Walmart for ~$8 bucks a can and that fills my DEF tank up approximately half way. Checking the date made is important as DEF fluid older than a year shouldn't be used and this, in my opinion, is one reason to not go with Ford's. You can't be sure how long it's sat on the shelf cause no-one is paying the price they charge for their bottled cat piss.

My dealers turn over their stock quite regularly but use what you want, I guess if you plan to keep the truck till 200 thousand plus miles it could pay off to be safe than sorry. Why cheap out on a truck which retails for 60 plus grand?



Use what you want I have just bad things about the cheap stuff, but you can run what you want to in it. It is your truck.

There is still quite a bit wrong with what you're saying here. The BLUE def is API certified, and meets the exact same specs as motorcraft. No one should be afraid to run this. maybe your buddy poured it into his diesel tank.

As for the diesel fuel, the EU has mandated ULSD since 1999, and the US since 2006. The hydrotreatment of diesel fuel to remove Sulphur does remove lubricity components of the fuel, so this is nothing new, and is why biofuel is commonly used to replace the lubricity in the fuel, which is the case for "European diesel". Since this is not mandated in US diesel, it is a good idea to use a lubricity additive to ensure the pump is protected.

As for the pump now, The pump in your tank is a lift pump and you don't need to worry about it, if this "disintegrates, there are 2 filters before it can get to anything critical, I have not heard of any issues with these. What you need to worry about is the High Pressure fuel pump, as this is behind the filters on the engine. The fuel doesn't "dry it out" as you've stated, it's a metal piston in a metal cylinder that relies on the fuel for lubrication. Inadequate lubricity can lead to scuffing and eventual failure, which will send metal shrapnel to your injectors and destroy them, so again a lubricity agent is a good idea here for peace of mind.

Yes the last statement is what I was referencing, it sent metal fragments into the fuel system thus having to have it completely redone. I just am not sure about the dates on Motorcraft DEF fluid, there is no expiration date on them but a inventory maker date and they are sealed bottles. I have heard of blue DEF destroying the heating mechanisms within the Ford def tanks within as little as 60 thousand miles. Again, this is not first hand knowledge but referenced from talking to the head diesel mechanic at my dealership and the multiple examples on the inter webs. I guess it is better to be safe than sorry as far as I am concerned but I doubt I have the truck this time next year as the new bronco is very appealing if it is done right.



Then again I do love my diesel Fx4, and so far it has been flawless up to 28 thousand miles.

What Laytunes is describing above just happened to my boss's truck. He had a 2015 2500HD Denali with just over 100k miles on it and the high pressure fuel pump grenaded! Sent metal fragments all through the fuel system. Basically had to trade it in and take the hit because the repair estimate was between $10k to $12k! Guess I will start adding the XPD in my tank. I know some trucks I have read it is bad for? Specially read something on the 6.7 Cummins where it was explained why not to use it. If it's all good on these 3.0 motors though I"ve always been a fan of it. Carry on.. : )

Standyne is supposed to be ford approved and will not void the warranty

DEF fill

Just use the plastic fill insert located under the rear seat, passenger side, packed along with the jack.!!
