Oil change interval Ram CTD .
I can't find the post but someone here questioned my 15,000 mile oil change interval , subject said his said 10,000 . I looked it up in my book and it does say 15,000 miles ! I can see some confusion...

I changed my oil first time 2015 Cummins at around 4K I used a FleetGuard Stratapore filter and AMZ/OIL 15-40 full Synthetic oil. I have around 9K on oil so based on my type of driving towing 32,500# combined and no short trips the computer is saying change at near 15K. I will change at that time and do an oil analysis with Blackstone that will include TBN.
I used to run the 15-40 in my 98 12V 10K analysis said to go to 13 on next sample.
