I’m looking into swapping my oil pump and using higher weight oil for my 2011 5.7. But I have some questions first.
Whenever I first fire up my truck, my oil pressure is anywhere between 25-33psi.
However whenever the engine heats up, cruising on the highway at 50-70mph my oil pressure drops down to around 15-18psi. And when coming to a stop it drops down to about 4psi and throws a low oil code at me. Would this be because the oil pump is bad? Any advice is appreciated!
