Has anyone used Seafoam

I have no idea the previous oil type history. I only have 2k on the Rotella, do you thing that would be an issue? I have 24k on my 2013

You can put in the more free flowing GN4 (10w30) and see if that alleviates the perceived tick you are hearing. As I mentioned earlier, I'm running 5w40 Rotella, not 15w40.

I meant to say that you should stay with a synthetic since that oil's properties exceed dino oil for longevity; such as shear life and contaminant suspension.

I'm also not 100% sure it's not an injector I hear ticking. I'll change it in the next couple weeks and report back.

Very posable if ya run OEM exhaust or a quite exhaust system. I know when my Dr. Jekill & Mr. Hyde exhaust system is closed I can hear my fuel injectors tick.
