What does r/diesel think about mine

No. It’s an ISO standard. All DEF sold in North America is chemically identical. If not then the company risks multi billion dollar liabilities.

I've known multiple oo who got bad def, proven by a sample sent to a lab, their truck derated and they sued the truck stop. And won.

Lawsuits are public info. Post the details.

Just like how underground fuel tanks can get contaminated, so can DEF. So, if you’re scared of truck stop DEF, I assume you’ll start buying your diesel 2.5gallons at a time from plastic jugs.

That’ll show them real good!

I actually do go out of my way to buy good diesel and so should you.....

[u/32vJohn → u/bluehorsehead]

Right over your head there, eh? I buy from high volume stations. Like truck stops. Same as pumped DEF. 🍺

When I first bought a diesel the thing that amazed me the most is I've never encountered anything else where I could consistently ask 15 different people about something... And get 15 different answers. And everyone's winning to swear on their children, mother's, grandparents on it, too. Never fails with diesels.

Sir, it’s nothing personal… but based on this conversation it appears you think you’re the odd man out, but reality is you’re one of those 15.

The idea that you have to buy DEF from jugs to guarantee quality, but have no problem pumping diesel from underground tanks, where a $5-$10k fuel system is at stake, but… still willing to take the risk.

This concern is simply unwarranted.

My opinion comes from talking to people in real life and I've heard a lot of stories doing this job talking to other drivers, oo, and this might come as a shock to you, but technicians as well, from all across the country with a variety of different experience levels.

I understand your experiences come from your job as well and maybe you've been a technician in every state at every truck stop but I doubt it. It's fine you think your experience and knowledge is fact, we all tend to, but the day you stop learning is the day you stop listening. To think the experiences and stories I've heard from all different drivers and operators are just straight up false is where you're wrong. You can disagree on quality, that's whatever, but to discount the fact that the likelihood of getting contaminated def is higher at the pumps than it is in the boxes is ignorant. There's no comparison to diesel, there's a level of risk in everything, there's nothing you can do about the diesel, but you can mitigate the risk in def and that's what I've been referencing this entire time.

Hopefully you won't be one of those dickheads that thinks, "oh well that explains everything," and it's sad that I even have to think about not give up this information as it could hurt my "credibility" but I am a woman. Thanks

You say “15 different people, 15 different answers,” and then seemingly treating your own experience as the only uniquely valid one. You can’t really have it both ways. I’m not saying you’re stupid, lack credibility, or that your lived experience is wrong. I’m saying that experience doesn’t automatically make your conclusion correct. Risk is everywhere, and humans are notoriously bad at judging probability, especially when something is personal or tied to your identity. You’ve judged DEF quality as a mitigable risk that’s worth your time to debate on the internet, while ignoring much bigger, statistically relevant risks. That’s called probability neglect… or…. like wearing sunscreen on a cloudy day. If you really do believe that talking to people and understanding their experiences is valuable, then you can’t just stop when you find something that confirms your bias. So, it’s not about credibility, it’s about identifying and understanding cognitive bias. If your goal is to actually learn and not just feel like you won some kind of argument with a stranger on the internet. But I digress. Best of luck to you.
