I am about to finish my aftermarket gauge installation, and I have to get one last gauge to purchase: OIL PRESSURE.

What is the normal F350 SuperDuty 6.0L Oil Pressure?

The gauges I can chose are (1) 0-100psi OR (2) 0-200psi.

I don't want to buy the wrong one. I already have an electronic HPOP gauge, but the oil pressure gauge will be analog for direct pressure readings.

Any help will be greatly appreciated. Thanks.

 

Which oil pressure are you going to be measuring?

Base engine oil pressure, or high pressure oil pressure?

Base engine oil specifications are as follows: 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.

High pressure oil, I would not recommend measuring with a mechanical gauge. You don't need a line blowing off with over 3000psi going through it. Just my .02.

You will need to rig up a setup to split the oil pressure switch to keep the oil pressure lamp off.

 

Short answer: a 100psi gauge should work okay.

I have seen a 6.0 at 150psi, however. Wow did that thing ever leak oil.

 

Thanks a lot! 100psi it is. Mechanically, I am going to measure the normal operating pressure, via a port near the oil filter, er, I think it was on the low pressure side of the HPOP. I have to look and find it first, I was told it was there. I just have to look and verify it. Any help? I know where the fuel pressure port is, but I need help with the oil Pressure and Oil Temperature ports. Clay @ riffrafdiesel.com told me where it was, but I haven't had time this weekend to get into the truck.

As for the HPOP, I bought an ISSPRO EV2 HPOP gauge which splices into the HPOP signal. That way I can see if the HPOP pressure ever drops: thus keeping my injectors happy, or noting a drop in pressure before the HPOP dies or a seal leaks.

Thank you very much for your help, BigAngryHillbilly.
