Good news: Trump Administration Announces Latest Action to Address Diesel Exhaust Fluid
Good news: Trump Administration Announces Latest Action to Address Diesel Exhaust Fluid
New rule says engines must be able to run with a DEF fault, with only a mild derate, for 4,200 miles or 2 work weeks.
After 4 weeks it will derate to a 25mph max speed.
Also the initial warning needs to come at 650 miles. This would have fixed some DEF issues my 2020 f350 had when towing.
Seems like common sense.
Yall should own a newer Toyota product. All the weird little tuning things to achieve lab test mpg and emissions misc cause a lot lot of drive ability issues. Would rather deal with the DEF.

Not good enough. DEF issues are sidelining trucks for months. Drastically increasing shipping costs of everything. Doubling the cost of travel for any heavy service job.
An overwide semi truck must have sone kind of special permit. I sat in a truck with a twin turbo Cat, and bored out heads for industrial engine injectors. It ran clean. Its time to relax on emissions garbage.
My company just ordered a bunch of 7.3 gas trucks.

An EO or EPA action to remove DEF requirement is DOA with CA and rest of the CARB states filing law suits immediately.
If white house changes hands in 2028 then the next admin is coming for the gas trucks next. Get as many 7.3 as you can now before they too get saddled with GPF, direct injection, cylinder deactivation, hybridization, and who knows what else, and get involved in congressional election campaigns in your local area.

I think everyone can see the cost of everything going up. Using tariffs for a political excuse as to why, only works on the uninformed peasants.
I just quoted an ignition module and catalytic convertor at a sewage water plant. The ignition failed, causing a lean condition that nuked the catalytic convertor. $40k quote, on top of the $10k in diagnostic already performed. On a clean green natural gas engine that really requires no catalytic at all. They could have bought a nice diesel engine, with no emissions at all, but got duped into this eco junk. I suspect that this kind of repair will happen again.
Theres being green concerned, and thats good. But the level of Karen we're at right now, can not be maintained. If congress needs term limits (or a taste of aggressive freedom), so be it.

Like it or not, longer more established legislative representatives are theoretically easier to be reasoned with than younger firebrands who have nothing to lose and just want to make the most mark in the shortest possible time frame. Are the likes of Schumer or Pelosi diesel-friendly? Of course not, but they are easier to lobby than say, AOC or Jefferies.
Those who are complaining how diesel regulations are not being dropped fast enough just because a different guy is in the white house need some serious civics lessons. Where were they when successive previous admins rammed through more and more strict regulations? Did they get involved in elections via grassroots action and donate to political action committees? No. As I recall when the DPF and DEF requirements were implemented the "old hands" were complacent because "Oh well there are plenty of used 7.3 PSD/12v Cummins/LB7/LLY/LBZ to choose from".
Sitting around and complain things are not getting better quickly enough gets you only so far. Too many people in this country sit around and complain but when it comes to midterm elections or special elections they can't even be bothered to go to the voting booth or even send in mail in ballots where those are allowed.

Being green is a great and lofty goal but you can’t bankrupt people and businesses to get there. If you do that then the game is over. It is the equivalent of a successful surgery that kills the patient. It doesn’t matter. This country has lost its mind in this manner.
Anyone ask Abraham Lincoln how the play was?
