Let me preface this by saying that as a 15-year (and counting!) service member and combat veteran, I do not support the acts insubordination or desecration of the dead that these operators (allegedly) performed...

The cost of DOC/DPF+SCR and urea dosing system for HDD (Class 8) applications is roughly 10k. You’re correct that the cost of the light heavy-duty pickups should be significantly lower.

This article and the Reddit threads had me in stitches.

Not really out of touch, just more of a pessimist/realist. I do agree that it is completely avoidable, but I feel that humanity mostly lacks the forethought or selflessness to redirect it at this point.

The United States is one small cog in the rest of the machine. Without global emissions regulations and enforcement and distribution of knowledge and technology to developing countries, the changes we make in policy and industry effectively stop at our shores. Meanwhile, China, India and South America continue to…

Not disagreeing with you, but I want to explain why I submitted my claim at the beginning of the window...

That’s glowing praise, for sure. When it comes time to replace my V wagon, I will give them a shot!

Clearly, my level of ignorance about Lexus is indicative of the number of fucks I have to give about Lexus.

I mean, what the fuck is this mish-mash of random lines and bulbous surfaces?

All good points. May I add that the same should be done with transmission and differential fluids? That same wear-in of components you’ve described is occurring in those components as well and they are easily overlooked.

Man, that will be great for the OEMs... Not so much for the consumer and the increase in urea consumption.

Blue Jeans Metallic. Sooooooo beautiful. I pretty much got the same truck, but with SRW and in Bronze Fire.

So there’s two times you would see sublimation (change of state from solid to gas, for everyone else). Both instances involve are a high heat/cleaning event - names like parked/moving/in-mission regen, DM protection, crystal prevention, etc.

You’re good brother. Read through the rest of the comments. Another fellow and I had some good discussion on aftertreatment basics.

I’m agreeing with you.

Not to mention that DEF quality monitoring is a thing and would result in a MIL and start inducement (torque/speed derate) which would eventually disable the vehicle.

That’s super interesting. Soot is basically unburnt fuel, and running diesel through the SCR is a huge no-no. The sulfur in diesel poisons the catalyst and creates dead spots over time/with exposure. I am really curious as to why Ford went that route. Maybe they reaaaallly need all of the heat they can get from the…

So it is a degreening of the DPF/SCR. This is typically done to bed-in the filter/catalyst strata. Good to know.

That’s also beside the point and I am not disagreeing about the presence of fuel/oil in the DPF.

Uhmmm, DPF filters inject fuel into the exhaust as part of the cleaning process for the filter.
