It wasn't till the 2019 Cummins (new CGI block) you started hearing about engine failures. What “engine failures” are you hearing/posting about? I have had my ‘24 Ram 2500 w/6.7 CTD six months only, and it Tows beautifully and I’m having zero problems even when temps dropped to 15F.
I have a 2025 RAM 2500 with the 6.7L Cummins engine and I want to make sure I use the right motor oil and I've always used Shell Rotella. I looked in the owner's manual and searched for the correct motor oil that meets the proper specifications. Shell Rotella 10w-30 T6 lists every spec except...

So I had a Gen4 cummins. Now I have a Gen5 6.7L cummins in my new 2500. So I see that the recommended oil is now either 10w-30, or 5w-40. The thing is I have a lot of the rotella 15w-40 oil in jugs still. Should I not use this in the summer season?
