curious myself

 

i havent been able to get Torque Pro for android to read the sensor. its there just shows inactive... Nevermind its got oil and trans temps not pressure.

 

Scangauge works on my 2009 5.3

 

i think dbnissan(somethin like that) had put an oil pressure sender on for a aeroforce gauge, he could probably tell you.

 

Yup, the oil pressure sensor in the 4 and 5 cylinder trucks is just for the indicator light. To get a PSI reading, you will have to install a true pressure sending unit and a dedicated oil psi gauge.

Mine runs at about 14-18 psi at idle and around 35-45 psi at 2000 rpm.

 

Wow that's scary low

 

Yeah, I'm used to my SBC maxxing out the Oil Pressure gauge at 100 psi. :shrug:

An oil pressure gauge would be kind of cool... Hrmmmm....

 

At idle in a warm engine that is normal from what I have seen in all of my past vehicles. I have seen it as high as 100 psi in my WS6 T/A when the engine was cold. It may have something to do with the low weight of the oil being it's 5/30 :shrug:

 

I was thinking 40-50 base and 50-60 in upper rpm

 

The only time I see the pressure that high at idle is at initial cold-start in the morning or after a few hours of the engine sitting. Once the engine warms-up, the oil lowers it's viscosity and the pressure drops accordingly. All of my work trucks displayed the same behavior and they all ran to 200k+ miles without any lubricating issues. Same with my 355 which is now at 174k miles

 

that is low. Mine reads about 30 psi at idle with mobile 1 5w-30

 

Here's mine after a 40 mile drive this morning.

Now, it is cool and rainy this morning. I too run 5-30 Mobil 1 and it was changed 3 weeks and 3000 miles ago. If it was too low, the PCM/BCM would tell me lol
