DD15 Oil pressure at idle

You want to idle that engine at 800 to 850 at night no lower then that keeps the oil pressure up above 32 psi it's good

 

I got a 2008 freightliner cascadia that has a 14.1 liter and keeps getting lower oil pressure. When start and idle it's at 50 psi then it drop below 20 psi. I've changed the oil pressure sensor and oil pump and still the same. Would a bad injector cause a low oil pressure too.

That’s just normal. All engines do that. At startup the oil is cold and thick, it thins out as it warms up.
