2024 Chevy Duramax Oil Capacity 2024. My 2020 6.6 would go to 80 psi when cold. Acdelco oil filter is suggested but other aftermarket options are available as well.

I also answer some questions from the last walk under video. Oil pressure is between 19 and 21 psi once in a while it will jump to 37 but drop right back down to 19 regardless of engine temp.
