What's your RPMs and oil pressure at idle?

7 PSI is the rock bottom minimum.... but, indicates that bearings are worn, and the engine is on its last legs. That said.... the sending units in these trucks suck. Checking with a mechanical gauge, to see what is REALLY happening, isn't a bad idea.
My gauge lies thru its teeth. It shows right about 40 PSI, even when the oil pressure light is on solid...... (hot idle in gear.)

Mine is 35 psi @opt temp in gear @ idle rpm, @ 2000 rpm it's 65 psi. Idle rpm in gear is 650-700. Edit; That's using full synthetic 5-40 oil.
