Hello I hope you can help me, I have a Ram Laramie 3500 High Output year 2022, I have a year with my truck, and it's doing regen almost every day, I have 9,450 miles on my truck, I use this truck every day to go to work, about 40 miles back and forth, I noticed a lot of people with this year of...

I brought this post over from another thread to try and allow that topic to have more focus and instead give us that wanted to discuss diesel emissions, and others who may not be aware of the conversation, ample space to do so. And also to make @Brutal_HO 's job easier, maybe. I agree that the...

Hello, I am new to this site and at an absolute loss. 40,000 kms on rental vehicles in less then two years due to my 2019 ram 3500 bighorn being a lemon. Has anyone had consistent issues with their emissions systems? Mine has been in the shop at least 6 times in the last year and half. Currently...

Peak now has a “Platinum” version of their BlueDEF which supposedly “reduces future deposits” in the exhaust/SCR. Sounds like marketing b.s. to me... Does anyone have any data to suggest this is a worthwhile investment? It costs about 40-50% more, which still doesn’t add up to much, but I have...
