Oil Pressure

[smokersteve]

As I'm driving and going through the rpm ranges and throttle range I notice the Eng oil pressure gage never moves. I have never noticed the stock oil pressure gage fluctuate.

Should this be???

[HVAC SuperTech]

no, the stock oil pressure guage is basically a dummy guage that goes up at 9 psi. When you start the truck, you can watch it come up as you first start it up. Dont go by anyhting on that guage. Its pretty much worthless.

whats the average Oil Pressure of the 7.3s?

[smokersteve]

Yes I do notice the fluctuation at start up. 9psi sure seems low but I understad thats a good psi. I think it would be nice to adjust it to 9.5 or even up to 10 psi.

You should go on the 7.3 forum to ask that. not too many 6.0 guys my know that. but im sure many do.

9 psi will hardly let the truck run. you need somewhere around 20-25 PSI at warm idle for a 7.3. About the same for 6.0

WOT, I see about 50 PSI in mine.

You cannot adjust the oil pressure on our trucks cause the pump is turned by the crankshaft. The guage is basically a dummy switch, nothing more.

For the 6.0L:

The minimum engine oil pressure specifications are 82.7 kPa (12 psi) at 700 rpm, 165.5 kPa (24 psi) at 1,200 rpm and 310.3 kPa (45 psi) at 1,800 rpm with the engine at operating temperature.

The oil pressure switch activates at 5 psig.

The oil pressure regulator opens at pressure of 75 psig to send flow back to the pump suction.

is there any way to hook up an after market oil psi gauge that is more accurate? if so what brand is good

[HVAC SuperTech]

Yes, have one hooked up in mine. Its a Stewart Warner, matches my other guages.
There is a square 1/4" plug on the last rib of the engine block next to the transmission. on the drivers side. take that plug out and hook it up there.

Is that for the 6.0?
