I know that this subject has been beaten to death over the internet, but still leaves me confused with no definitive answers. Only things that I know for sure, are the factory minimum specs, and the old rule of thumb 10psi per 1000rpm.
Since I have a great trust for the knowledge that the folks on BITOG have, here goes.
So my truck is a 2008 Chevy Suburban 6.0 with 90k on the clock. I'm running Mobil1 ESP 5w-30 and a WIX XP oil filter, been there for 4000 miles. Oil pressure sensor changed same time with the oil.
Cold start, oil pressure is 40psi. 1500rpm on highway, starts slowly dropping when the engine warms. It will stay in 25-30psi @ 1500rpm after 20 miles when the engine is properly hot. Idle psi when fully warm is 20psi or a hair over. Needs ~2500rpm to get near 40psi hot.
Everything works and sounds perfect.
Some say it's fine, some say it's half what it's supposed to be. I am aware of the common problem with the oil pickup tube o ring, but I've understood that the symptoms go the other way round (low psi cold, normal hot).
What do you guys think? What kind of oil pressure are you having on those engines (2007-2014)?
