Does the DEF System on a Diesel Engine Actually Do Any Good?

Introduction

The claim in question revolves around the effectiveness of Diesel Exhaust Fluid (DEF) in diesel engines. Specifically, it asks whether the DEF system contributes positively to engine performance and emissions control. This topic is particularly relevant given the increasing scrutiny on diesel emissions and the regulatory frameworks aimed at reducing harmful pollutants.

What We Know

  1. Definition and Purpose: Diesel Exhaust Fluid (DEF) is a mixture of urea and deionized water, primarily used in Selective Catalytic Reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions from diesel engines. It is injected into the exhaust stream, where it reacts with NOx to convert it into nitrogen and water vapor, significantly lowering harmful emissions 14.

  2. Emissions Reduction: Studies indicate that DEF can reduce NOx emissions by as much as 90%, helping diesel engines meet stringent environmental regulations 8. This is particularly important as many regions have implemented strict emissions standards for diesel vehicles.

  3. Engine Efficiency: Some sources claim that using DEF can enhance engine efficiency, fuel savings, and longevity. For instance, one article states that DEF usage is linked to improved engine performance and reduced operational costs 25.

  4. Regulatory Compliance: The use of DEF is often mandated in newer diesel engines to comply with environmental regulations, which aim to limit air pollution from vehicular sources 6.

  5. Potential Drawbacks: Critics argue that the introduction of DEF systems may negate some of the inherent advantages of diesel engines, such as fuel efficiency and power. Some discussions suggest that reliance on DEF could complicate maintenance and operation 79.

Analysis

Source Evaluation

  1. Credibility and Bias:
    • All American CDJR 1: This source appears to be a dealership blog, which may have a vested interest in promoting diesel vehicles and their associated technologies. While it provides factual information, it may lack objectivity.
    • Ricochet Fuel 25: These articles promote the benefits of DEF, suggesting improvements in efficiency and performance. However, they are from a fuel company, which could introduce bias in favor of DEF usage.
    • My Engine Specs 3 and DFC Diesel 4: These sources provide technical explanations of how DEF works. They seem to be more focused on educational content rather than promotional, which may enhance their reliability.
    • Gaubert Oil 6: Similar to Ricochet, this source is from an oil company, which may influence its perspective on DEF's necessity and benefits.
    • Smokstak Forum 7 and IRV2 Forum 9: These are user-generated content platforms where opinions may vary widely. While they can provide anecdotal insights, the reliability of information can be questionable due to the lack of expert verification.

Methodology and Evidence

The effectiveness of DEF systems is often supported by empirical studies and regulatory reports, which are not always cited in the articles reviewed. For a more comprehensive understanding, peer-reviewed studies or government reports on emissions reductions and engine performance would be beneficial. Additionally, independent assessments from automotive engineering experts could provide a more balanced view of DEF's impact.

Conflicts of Interest

Several sources are affiliated with companies that sell diesel fuel or related products, which may lead to a bias in favor of DEF. This potential conflict of interest should be considered when evaluating their claims.

What Additional Information Would Be Helpful?

To further substantiate the claims regarding DEF's efficacy, the following information would be valuable:

  • Peer-reviewed studies quantifying the long-term impacts of DEF on engine performance and emissions.
  • Independent assessments from automotive engineers or environmental scientists.
  • Comparative analyses of diesel engines with and without DEF systems over time, focusing on performance, maintenance, and emissions.

Conclusion

Verdict: True

The evidence supports the claim that the DEF system in diesel engines contributes positively to emissions control and can enhance engine performance. Key findings indicate that DEF can reduce nitrogen oxide (NOx) emissions by up to 90%, which is crucial for compliance with stringent environmental regulations. Additionally, some sources suggest that DEF usage may lead to improved engine efficiency and reduced operational costs.

However, it is important to acknowledge the context and nuances surrounding this verdict. While the benefits of DEF are well-documented, there are criticisms regarding potential drawbacks, such as the complexity it adds to maintenance and the possibility of negating some advantages of diesel engines. Furthermore, many of the sources discussing DEF's benefits are affiliated with companies that may have a vested interest in promoting its use, which introduces a potential bias.

The available evidence, while substantial, is not exhaustive. More independent and peer-reviewed studies would help clarify the long-term impacts of DEF on diesel engine performance and emissions. Readers are encouraged to critically evaluate the information presented and consider the broader context when forming their own conclusions about the DEF system's effectiveness.

Fact Check: Autistic Non-Verbal Episodes in Marriage: Why Words Vanish Sometimes and What to Do About It Neurodiverse Couples Tuesday, august 12, 2025. Here’s the scene: You’re in the middle of a conversation with your spouse. Maybe the topic is small (“Did you pay the water bill?”) or monumental (“Are we happy?”). And then—without warning—your autistic partner’s voice disappears. No yelling, no slammed doors. Just… gone. You’re left holding the conversational steering wheel while they’ve quietly climbed into the trunk. If you’ve never lived with high-functioning autism, this can be tragically misconstrued as stonewalling or contempt. It isn’t. It’s just neurology pulling the emergency brake. Why This Happens: The Science Without the Lab Coat Smell For autistic adults, losing speech under stress is often a shutdown—a form of nervous system overload that knocks language production offline. Think of it like your phone freezing: all the apps are still there, but none of them open when you tap. Research calls this autistic burnout when it happens in a longer, chronic cycle—linked to masking (Hull et al., 2017; Raymaker et al., 2020). Masking is the art of “performing normal” so well that non-autistic people think you’re fine. The issue is that it eats through your energy reserves like a car idling in traffic with the A/C on full blast (Mantzalas et al., 2022). Eventually, one hard conversation can tip you from functional to frozen. And here’s where couples therapy meets neuroscience: physiological flooding—the body’s fight/flight/freeze switch—is a known relationship killer (Malik et al., 2019; Gottman Institute, 2024). In other words, for some autistic partners, flooding may tend to show up sooner, last longer, and is more likely to pull the plug on speech entirely. The Danger Loop in Marriage Autistic partner goes non-verbal — brain says “nope.” Non-autistic partner reads it as avoidance — brain says “attack.” Pressure increases — “Just say something.” Shutdown deepens — and now you’ve both lost. Do that a few hundred times and you’ll start conflating a physiological response into a moral failing. That’s the real marriage-killer. The Protocol: Three Phases, Zero Guesswork This is where we get practical. You can’t “love away” a temporary shutdown, but you can stop it from turning into World War III. Before: Build the Net Name the state. Agree on a phrase or signal ( I call this a couple code)—such as “words offline,” “shutdown,” a hand over the heart. The point is to make the invisible visible. The Shutdown Card. A literal card that says: I can’t speak right now. Please lower lights, reduce sound, give me X minutes. I promise I will circle back. The Pause Rule. Require a minimum of 20 minutes before resuming any tough talk. Autistic partner may need 90+. Agree ahead of time. Downgrade Kit. the usual gear; earplugs, soft light, weighted blanket, fidget, a quiet room. You know, human decency in object form. Reduce Daily Load. Avoid heavy talks right after work or big social events. Chronic overload makes a nervous shutdown more probable. During: Do Less, Better Autistic Partner: Give the signal. Exit stimulation. Switch channels if possible (text, notes app, yes/no cards). Send a short pre-written message: “Safe, can’t talk, back at 8:15.” Non-Autistic Partner: Acknowledge once—“Got it, I’m with you.” Hold the pause boundary. Lower stimuli. Go regulate your own nervous system—walk, journal, pet the dog. Don’t rehearse comebacks. Both: Avoid sarcasm, interrogation, ultimatums. Nothing lengthens a shutdown like moral outrage. After: Close the Loop Check in: “Are you ready to talk, or should we start in text?” Debrief: Identify triggers and what helped. Solve the actual problem. No conflict gets left to rot in the corner. Spot burnout early. If shutdowns start clustering, it’s time to reduce demands, not double them. How This Isn’t Stonewalling Stonewalling is a choice. Shutdown is a lockout. Stonewalling says, “I won’t talk to you.” Shutdown says, “I can’t talk to you yet, but I will.” The key difference? Repair intention. A shutdown protocol builds that right into the process. The Ten-Minute At-Home Drill Co-create your signal and card. Agree on a pause window. Pack the downgrade kit. Rehearse the exchange (“Got it, I’m with you.”). Check in weekly to tweak the system. Remember, you’re not aiming for zero shutdowns. You’re aiming for shorter, kinder, safer ones. Why This Works Because it matches lived autistic experience (Raymaker et al., 2020; Lewis et al., 2023). Because it honors nervous system limits instead of punishing them (Malik et al., 2019). Because it lets both partners keep their dignity and still solve the problem. In other words: you’re building a marriage that can survive the occasional moments when the words are gone for the time being. Be Well, Stay Kind, and Godspeed.

Fact Check: 11 YR OLD SHOOTS ILLEGALS thanks FOX NEWS for reporting it.

It seems the two crooks never learned two things: they were in Montana and Patricia had been a clay-shooting champion since she was nine.Patricia was in her upstairs room when the two men broke through the front door of the house. She quickly ran to her father's room and grabbed his 12-gauge Mossberg 500 shotgun. Resindez was the first to get up to the second floor only to be the first to catch a near point blank blast of buckshot from the 11-year-old's knee-crouch aim. He suffered fatal wounds to his abdomen and genitals.When Garza ran to the foot of the stairs, he took a blast to the left shoulder and staggered out into the ...street where he bled to death before medical help could arrive. It was found out later that Resindez was armed with a stolen 45-caliber handgun he took from another home invasion robbery. That victim, 50-year-old David 0'Burien, was not so lucky. He died from stab wounds to the chest.Ever wonder why good stuff never makes NBC, CBS, PBS, MSNBC, CNN, or ABC news........?

Fact Check: Paul Krugman Paul Krugman We’re All Rats Now Time to take a stand, again, against racism Paul Krugman Jun 30, 2025 Zohran Mamdani’s upset victory in New York’s Democratic primary has created panic in MAGAland. Stephen Miller, the architect of Donald Trump’s deportation policies, waxed apocalyptic: Scott Bessent, the Treasury secretary, declared that New York is about to turn into “Caracas on the Hudson.” And Sen. Tommy Tuberville of Alabama basically declared New York’s voters subhuman, saying: These inner-city rats, they live off the federal government. And that’s one reason we’re $37 trillion in debt. And it’s time we find these rats and we send them back home, that are living off the American taxpayers that are working very hard every week to pay taxes. These reactions are vile, and they’re also dishonest. Whatever these men may claim, it’s all about bigotry. Miller isn’t concerned about the state of New York “society.” What bothers him is the idea of nonwhite people having political power. Bessent isn’t really deeply worried about Zamdani’s economic ideas. But he feels free, maybe even obliged, to slander a foreign-born Muslim with language he would never use about a white Christian politician, even if that politician were (like some of his colleagues in the Trump administration) a total crackpot. And while Tuberville stands out even within his caucus as an ignorant fool, his willingness to use dehumanizing language about millions of people shows that raw racism is rapidly becoming mainstream in American politics. Remember, during the campaign both Trump and JD Vance amplified the slanders about Haitians eating pets. And now that they’re in office, you can see the resurgence of raw racism all across Trump administration policies, large and small. You can see it, for example, in the cuts at the National Institutes of Health, which are so tilted against racial minorities that a federal judge — one appointed by Ronald Reagan! — declared I’ve never seen a record where racial discrimination was so palpable. I’ve sat on this bench now for 40 years. I’ve never seen government racial discrimination like this. You can see it in the renaming of military bases after Confederate generals — that is, traitors who fought for slavery. You can even see it in a change in the military’s shaving policy that is clearly custom-designed to drive Black men — who account for around a quarter of the Army’s new recruits — out of the service. So racism and bigotry are back, big time. Who’s safe? Nobody. Are you a legal immigrant? Well, the Supreme Court just allowed Trump to summarily strip half a million U.S. residents of that status, and only a fool would imagine that this is the end of the story. Anyway, when masked men who claim to be ICE agents but refuse to show identification are grabbing people off the streets because they think those people look illegal, does legal status even matter? Does it even matter if you’re a U.S. citizen? And the One Big Beautiful Bill Act is set to massively increase ICE’s funding — basically setting up a huge national secret police force. Now, maybe you imagine that you yourself won’t suffer from this new reign of bigotry and imagine that everyone you care about is similarly safe. But if that’s what you think, you’re likely to face a rude awakening. I personally don’t have any illusions of safety. Yes, I’m a native-born white citizen. But my wife and her family are Black, and some of my friends and relatives are foreign-born U.S. citizens. Furthermore, I’m Jewish, and anyone who knows their history realizes that whenever right-wing bigotry is on the ascendant, we’re always next in line. Are there really people out there naïve enough to believe MAGA’s claims to be against antisemitism, who can’t see the transparent cynicism and dishonesty? The fact is that the Trump administration already contains a number of figures with strong ties to antisemitic extremists. The Great Replacement Theory, which has de facto become part of MAGA’s ideology, doesn’t just say that there’s a conspiracy to replace whites with people of color; it says that it’s a Jewish conspiracy. So I’m definitely scared of what the many antisemites inside or with close ties to the Trump administration may eventually do. And no, I’m not frightened at all by the prospect that New York may soon have a somewhat leftist Muslim mayor. Anyway, my personal fears are beside the point. Everyone who cares about keeping America America needs to take a stand against the resurgence of bigotry. Because the truth is that we’re all rats now.

You can see it in the renaming of military bases after Confederate generals — that is, traitors who fought for slavery. You can even see it in a change in the military’s shaving policy that is clearly custom-designed to drive Black men — who account for around a quarter of the Army’s new recruits — out of the service. So racism and bigotry are back, big time. Who’s safe? Nobody. Are you a legal immigrant? Well, the Supreme Court just allowed Trump to summarily strip half a million U.S. residents of that status, and only a fool would imagine that this is the end of the story. Anyway, when masked men who claim to be ICE agents but refuse to show identification are grabbing people off the streets because they think those people look illegal, does legal status even matter? Does it even matter if you’re a U.S. citizen? And the One Big Beautiful Bill Act is set to massively increase ICE’s funding — basically setting up a huge national secret police force. Now, maybe you imagine that you yourself won’t suffer from this new reign of bigotry and imagine that everyone you care about is similarly safe. But if that’s what you think, you’re likely to face a rude awakening. I personally don’t have any illusions of safety. Yes, I’m a native-born white citizen. But my wife and her family are Black, and some of my friends and relatives are foreign-born U.S. citizens. Furthermore, I’m Jewish, and anyone who knows their history realizes that whenever right-wing bigotry is on the ascendant, we’re always next in line. Are there really people out there naïve enough to believe MAGA’s claims to be against antisemitism, who can’t see the transparent cynicism and dishonesty? The fact is that the Trump administration already contains a number of figures with strong ties to antisemitic extremists. The Great Replacement Theory, which has de facto become part of MAGA’s ideology, doesn’t just say that there’s a conspiracy to replace whites with people of color; it says that it’s a Jewish conspiracy. So I’m definitely scared of what the many antisemites inside or with close ties to the Trump administration may eventually do. And no, I’m not frightened at all by the prospect that New York may soon have a somewhat leftist Muslim mayor. Anyway, my personal fears are beside the point. Everyone who cares about keeping America America needs to take a stand against the resurgence of bigotry. Because the truth is that we’re all rats now.
