Oil Pressure

What should my oil pressure gauge be at when the truck is at full running temp and at idle ?

Mine is at 40 but, I noticed a big jump when I went to mobil !

ok thank god ! . I thought since it was so low and not at 275 like when you are on the gas , that there was sometin wrong .
I have 89500 MILEs on my truck , is that alot ? when do these engines wear out ?

I run mobil 1 synthetic and mine stays around 40

if you take care of everything you should get atleast 200000 hopefully more

uh oh , I just looked at a oil pressure guage on a USADM Crew Cab . And the gauge is numbered different . 40 is in the middle ( where 275 is on mine ) so that means that if all your guages read 40 as the norm . then mine which usally reads to the left of that by about a 1/4 of a inch . meaning my oil pressure is too low .

at idle mine is lower . 40 for me is at highway speeds

ok that sounds about right then . my needle is in the 12 o'clock positon at highway/ driving speeds . and lower at idle .

40 with mobil 1, maybe half on fossil oil

Oil pressure (minimum) at normal operating temperature:
6 psig @ 1000 rpm (42 kpa)
18 psig @ 2000 rpm (125 kpa)
24 psig @ 4000 rpm (166 kpa)

So I have a few things down with research but, Brule, remember the majority here

What is a "kpa"

Kilopascal (kPa)
Definition: A unit of pressure. 1 kPa is approximately the pressure exerted by a 10-g mass resting on a 1-cm2 area. 101.3 kPa = 1 atm. There are 1000 pascals in 1 kilopascal.

(metric stuff

)

I opened myself up for that one

Will remember to keep my mouth shut (as best I can) in the future
