6.7 Cummins detonation?

[MrScott]

I may be crazy but......
2016 350 6.7 with 150,000 miles.
Can my 6.7 diesel have the "ping" associated with gasoline engines running low octane gas or timing set incorrectly?
With all the beautiful sounds mu 6.7 makes, it has sounded like a slight ping on mild acceleration.
Not even sure this is possible with a diesel.
Anyone ever hear of this before?

I hear this same thing in my truck and I'm here looking for some answers maybe.
I'll be watching your thread.
Thanks

Diesel engines run by compression ignition.

They tend to be loud and clattery, especially the older diesels that don’t have the newer complex fuel injection systems to help quiet them down.

Diesels are susceptible to poor quality fuel. If yours is running well despite sole noise, then I’d recommend fresh fuel and maybe a bottle of good diesel specific fuel additive.

I buy a gallon of “opti-lube” and add a couple ounces per tank full. It’s cheap insurance and provides some lubricity to all the pumps and injectors moving the modern low sulfur diesel fuel. My Cummins seems to run a little smoother and quieter with the additive.
