re: EPA Set to remove DEF engine derate...

The diesel engines from ~ 2000 to ~ 2008 were absolutely horrible.

Completely false. There multiple engines from that era that are considered some of the best engines ever produced. The LBZ Duramax comes to mind.

Since we have a lot of diesel drivers, what’s the best diesel truck before DPF and DEF?

2006-2007 LBZ Duramax with Allison transmission would have to be the top or tied for the top. Was at the church working last Saturday and one of our members who has been a car salesman for the last 30 years came up. Looking at my truck he said, "You have the best truck ever made." I have yet to take it in for service and someone not approach me about buying it.

That said, there's some Dodge owners from that era that can make a good argument for some of their drivetrains.

Regarding Ford, I really don't know other than they had some major lemons. Had a good friend who is a Dr. who had his burn up in his driveway one morning.

People who want aftertreatment to go away have zero understanding of how it works or what it accomplishes. You get rid of DEF, you are back to shitloads of EGR, horrible fuel economy, and busted up garbage engines like we had prior to 2008. Do you REALLY want 11mpg and worn out engines at 100k miles so you don't have to buy DEF?

---

This is a stupid take. There are a shite load of older engines still running well over 11mpg and into the hundreds of thousands. I have a 2006 with the LBZ Duramax getting around 17 to 18 mpgs with a mix of hwy and city driving, hwy only gets closer to 20, with 260k miles. Would have no problem or doubts taking it on a cross country road trip.

The inter-years between mechanical engines and what we have now were what sucked. 2007-2013 might be what I was looking for there.

Now you're back to making sense.

Every 12 valve, 24 valve VP pump and 5.9 common rail Cummins says hello.....

The baw is saying the EPA isn’t going to revert to 1990 emissions regs.

How do the newer OTR trucks get away with deleted engines?


They don't.

Really the only state that'll mess with you is California, because it's California. We have guys get pulled over and DOT inspected pretty regular in several states, none have ever been asked/checked about emissions equipment, including the Freightliner that's been deleted for several years, we just don't send that truck to CA to play it safe.

My personal truck is deleted, but only because the equipment failed, if it wasn't for that I'd have left it stock, and I also run a pretty clean tune that only smokes a little if you lean into it pretty hard.

I actually don't mind them as they currently are except I wish the EGR systems would totally go away. You don't need them to meet emissions anymore, they are only there for warmup and controlling DEF consumption. I'd rather burn more chicken piss and not have an EGR system.

The issues now are way more NVH driven than anything else. Super high pressure fuel systems and goofy valvetrains and goofy block geometry and big goofy intake silencers all designed to make the engine quiet and smooth. It's nice, but all that shite is expensive and complicated.

The thing we REALLY don't want to talk about is that you could take a 1970's mechanical diesel engine and make it fully emissions compliant today. It'd be pretty bad on fuel, it'd need an EGR system, but you could do it and it'd be far cheaper than the space ship engines we have now.

And the only reason it could be made emissions compliant - SCR and DEF. The general principal is great, and everybody who hates it is misdirecting their hatred.
