https://www.msn.com/en-us/autos/news/global-urea-shortage-could-park-diesel-trucks/ar-AARJpAC?ocid=BingHp01&pc=BG00 This entire world economy is depending on China these days. I think cutting the apron strings is long overdue.

So, after over nine weeks sitting at Rush Peterbilt in Denver, and having to involve Paccar North America, my assigned 389 with the ISX has been released. We think that because the truck was not purchased there we went to the back of the line ahead of locals who did buy there. This DEF joke...

The main sensor that regulates the temperature, injection rate and a host of other things went bad on me Tuesday morning. The DEF gauge dropped to 0, the low fluid indicator came on, the check engine light came on and it threw a couple of codes. Then it gave me 4 hours of drive time until it...

I recently just got my cdl and purchased a 2015 Freightliner DD15 . Truck has been running smooth for the past couple months . I have been having some def issues though . How many filters does a DEF system have ? What is the difference between a DPF filter and regular def filter ? I notice the...

I've been told that Detroit seems to have had it figured out better than most. Any one have a comment on this? I do know we had tons of issues on the ISX cement mixers due to the dead head number six injector. Cummins fixed it, kind of, not really, more like a band aid.

Has anyone tried the walmart branded def fuel in the 2.5 gallons for $7/each? Seems like a good deal and ships free. DEF Fluid Diesel Exhaust Fluid 2.5 Gallon (2 Pack) - Walmart.com

Hello, I drive a 2012 peterbilt 386 and I have been experiencing lower mpg than usual and the truck asks for the regeneration to be perform at shorter time periods. When I place the truck in relay the truck feels like it is accelerated similar to when performing a regeneration. Cummins has...

Just got this message today along with the constant flashing exhaust symbol. Got a 100 mile jaunt up yo Fondy, WI Stopped at a rest stop 15 away from drop ask other truckers what their experience was when this happened. They said they ignored it but days later they were derated to 15mph or...

For those that would prefer to avoid issues with DEF. I recommend a small nitrile (rubber) Glove over the cap and neck. Replace after every fill up and no one says you can’t squirt a bit of DEF into a trash can to clean the nozzle...

First things first. I’d like to thank everyone that contributes on this site! The knowledge has helped me overcome and save a lot of money with fixing my truck myself. Thanks everyone. I have a 07 Pete 379 with a Cummins 475 ISX (no def system). Got the truck a few months ago and has been...

Perhaps someone can help with any suggestions? I'll give you as much info as possible so sorry for the long post (note: if relevant - I have a very heavy load). First, the DEF Fuel Guage cut-out and went to zero. Then it started flicking on and off intermittently. Then I got three fault codes...

Hey Everyone, looking to bulk up on DEF fluid for the year. Found the 55 gallons of blue def for $125 a barrel, wondering if anyone here has experience with Walmart's house brand DEF product. https://www.walmart.com/ip/DEF-Fluid-55-Gallon-Drum-Diesel-Exhaust-Fluid-4-Pack-Super-Value/625918580 LL

I been reading up about DEF Quality and a lot of times it's the sensor . I don't think that's my problem , or at least solely. Awhile back I started having DEF Quality issues so started writing down where I topped it up and put a check if I got issues then would follow up by toppling up there...

What year do you all think is the point the manufacturers generally got the emissions thing figured out to where you aren't in the shop more than on the road? Ideally I want pre-emissions but I gotta keep my mind open. Just don't want a complete turd. Do you think it's 2012? 2013? 2009?

In hot weather. What driving situation uses more def: high rpm/ downshifting/ etc ???

My cascadia is displaying an EEC 061 4364 fault 18 code which seems to have something to do with the DEF not being injected properly. Anyone got a little more insight?

Hello. I am new to trucking, I have only been driving for 20 years. On my last trip I filled my DEF tank before leaving at our yard. About an hour and a half into a thousand mile round, A fault code comes up saying DEF poor quality. The recommendation was drain and re-fill with quality DEF. This...

Hi everyone, I hope everyone has had a good week so far. I received some advice on this forum about what tractors to consider to spec out a small fleet. Thank you for that. I am not a driver myself so I come as a student but I love learning about this industry. I've read the following articles...

I was keeping an eye a few years back on a buy acquisition of a company called Amminex, a Dutch company, by Navistar, that made solid block, or cartridge, that had urea in a solid substrate. It supposedly would last about the length of time of a standard OEM recommended oil change, then be...

What do you guys think of the Cascadias with a DD15 in it and DEF. I have been reading a lot of negative comments about them. Any of you with experience have a say in this? Because we are debating on getting a International Prostar with a Cummins engine or this Cascadia.
