15-40W is good to 0F FYI -- the 5-40 synthetics though are good for all temperature ranges.i just did the ccf atmosfer relief mod on my 2011 and when i crancked it up after i was done i noticed that my oild pressure was at 46psi and the engine temp was around 98-110 and outside temp was 43f.
is this normal till all the oil gets warmed up?? i live in south GA and running OEM 15-40w but lately the winters have been getting colder and colder here so i might switch to 5-40 soon. i just want to make sure this sounds normal to anybody else??
sorry for hijacking your thread OP.
Thats how it is. I have a real pressure gauge installed and the idiot number on the dash is nowhere near accurate.Umm I thought the oil pressure gauge was just calculated off rpms?
I know that's not how it should be but that's how I thought it was on the 6.7s
I haven't looked in to this particular sensor, but pressure transducers are typically two wire sensors as well.Yep, if there's any doubt take a look at your 'sensor'...2 wires only, it's a switch. EVIC/dash gauge is virtual sensor.
I stand corrected, sir! You are correct in stating other engines could use 2 wire sensors which are actual transducers...however, ours are not.I haven't looked in to this particular sensor, but pressure transducers are typically two wire sensors as well.
If you look at some of the bigger trucks with the ISLs and ISXs, they have a 2 wire pressure transducer for oil pressure that the ECM reads, which the dash then reads off the datalink.
I'm not saying that it's the case here, but it's possible.
