i decided on 3k as my number. Completely arbitrary but I liked it. Felt the the engine was just starting to cook itself off under my foot

So the next question is

T6 or T4 15w-40?

15W-40 is not an option for a 2019+ Cummins. 10W-30 (T5) or 5W-40 (T6)

Yeah not sure who mentioned 15W40, It is my understanding that 5W40 is recommended for these Cummins. In my old 6.0 I also ran the T6 5W40 and had zero issues. I wish I did have some leftover as I cant seem to find any around here. Might have to look into Amsoil? Its $154 for thee gallons of the T6 on Amazon! Yikes!!

Ouch, at that price AMSOIL is definitely cheaper. DM me if you want to place an order and I'll help any way I can.

Shoot is swear I saw 5w40 in both t4 and t6 but I was mistaken. Ty
