EPA rolling back regs?

[fpgt72]

It looks like the EPA has ended its stupid regs requiring diesel exhaust fluid. If you are not familiar with this in a nutshell you had to put a fluid in your "exhaust" to make it cleaner. Looks like this is being reversed and the software to hobble the engine can now be charged to allow full power if no exhaust fluid is present.

Hopefully CAFE will be removed and we can get back to smaller trucks and cars that get better fuel mileage. My 1990 F150 was parked next to a Ford Maverick. The modern small truck is larger than my old full sized

The link won't let me view unless I drop my VPN proxy so I can't see the article details.

From what little I saw trickle into the news, the relaxed mandates on DEF are only aimed at diesels other than road vehicles. Is there anything more encompassing or is it really just tractors and equipment ?

Ugh, my latest Kubota M5-111 requires DEF. Would be nice when I have to buy another one in another decade if it didn't require DEF.

^ However, I know better and we are only one administration away from everything going back to the way it was.

The article said it was for on and off road vehicles.

Specifically

“will revise DEF guidelines for manufacturers of heavy trucks and off-road equipment”

I’m guessing “Heavy Trucks” is not inclusive of passenger vehicles.

Well would be nice to know the GVW they are actually talking about ? Knowing the usual gov. backhanded double-talk . If this only applies to heavier than 10-k GVW the average guy is still being fucked in the ass .

“We have heard loud and clear from small businesses across the United States that the current DEF system is unacceptable. It is unacceptable that farmers, truckers, construction workers, and many other small businesses continually experience failures of diesel-powered equipment when they need it most—costing millions of dollars in lost productivity,” Zeldin insisted. “Today, we are responding to those concerns by calling on manufacturers to take action to update their software and eliminate the unnecessary sudden loss of power and frustrating shutdowns that too many Americans have experienced.”

Very iffy on the wording - some articles say it's going to include normal pickup trucks but Zeldin's actual quote doesn't really support that.

Also, it's evidently just doing a slow derate (incremental derate over 100 - 800 miles based on different sources) if you run without DEF, vs the instant derate that happens now.

The darn diesel prices are still way stinking high! I drive an 06' 1 ton Dodge

Amurica is about to be rolling in coal, wait till all this squatted fag trucks are legally allowed to roll coal instead of just having a 14 inch exhaust tip blasting

Fucking whatever. As long as I can delete some German diesel 4-banger and get 60mpg I don’t care what these dipshits waste their money on

I'm trying to understand the hundreds of hours and millions of dollars due to the no performance impact they are talking about. You put DEF in when you refuel so how is this saving downtime. Oh yes, people are too stupid to read the gauge that is next to the fuel gauge.

I'm not a fan of aftertreatment systems but it does make a huge difference in the air quality whether people want to believe it of not. Run a 07 or older service truck in a shop to use the crane, then run new truck indoors and you will understand the difference pretty quick.

Imagine how pissed VW has to be bout now. How many TDI cars did they buy back hahahahahha.

I’m excited to see if it actually applies to consumer grade trucks or just heavy commercial sold style vehicles. If I could have deleted and tuned my ecodiesel, I think it would have been a completely different animal

Mercedes just went through some horseshit like this too. I’m planning on an E250 that gets every epa mandated part ripped off with a mild intercooler and tune upgrade

This guy has been following EPA guidelines and emission roll backs for a while. He’s been fairly accurate on his predictions and seems to know a few people in the administration that know what’s going on to say the least
