Hey everyone, I'm looking for suggestions on my problem.

 

I own a 2015 yukon xl with the 5.3, it's just hit 400k km, I did an oil change w redline 5w30 and a k&n oil filter (couple thousand miles before the extremely cold temps) and recently at start up the truck started making a low power steering fluid type noise, it would last a while then go away but now it's there longer, and can be heard when accelerating with rpms.

 

My oil pressure has always been 3 quarters on the guage but recently its been around 20 at hot idle but goes up as should while accelerating and steady at cruising. Am I looking at an oil pump replacement? Or could it be the oil weight or filter or maybe even both?

Time for an oil pump.
