Oil Pressure
Low Idle (minimum allowed) 69 kPa [10 psi]
At Rated Speed (minimum allowed) 207 kPa [30 psi]
Oil Regulating Valve Opening Pressure Range 448 kPa [65 psi] to 517 kPa [75 psi]
Oil Filter Differential Pressure to Open Bypass 345 kPa [50 psi]
Lubricating Oil Filter Capacity 0.950 liters [1 qt]

Lubricating Oil Capacity of Standard Engine
Rear Gear Train Engines (Standard Oil Pan)
Pan Only 14.2 liters [15 qt]
Total System 16.7 liters [17.6 qt]
High to Low (on dipstick) 1.9 liters [2 qt]

Lubricating Oil Capacity of Standard Engine
Rear Gear Train Engines (High Capacity Oil Pan)
Pan Only 17.2 liters [18.5 qt]
Total System 19.7 liters [20.8 qt]
High to Low (on dipstick) 2.8 liters [3 qt]

Lubricating Oil Capacity of Standard Engine
Front Gear Train Engines (Standard Oil Pan)
Pan Only 9.5 liters [10 qt]
Total System 11.9 liters [12.6 qt]
High to Low (on dipstick) 1.9 liters [2 qt]
Maximum Oil Temperature 138°C [280°F]

NOTE: If the type/oil capacity of each pan is not known:
•Contact a Cummins® Distributor/Dealer
•Determine the capacity of the oil pan option for the engine being serviced by using QuickServe™ Online and the engine serial number.
•Fill the lubricating oil pan to the smallest oil pan capacity listed for the engine being serviced. Then add 0.95 liters [1 qt] of oil at a time until it reaches the high mark on the dipstick. Record the number of liters/quarts added so the capacity is known the next time the oil is drained.

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.

15-40W is good to 0F FYI -- the 5-40 synthetics though are good for all temperature ranges.

Mine is a 2011.5/HO and I see a bit higher pressures -- new truck though (10k so just a baby) -- around 39-40PSI @ idle warmed up, and 50's running @ 1500RPM.

Mine is the same.

I was looking at mine today...did not feel like listening to news nor music. So i was watching my oil pressure gauge (idiot one and the EVIC display). Looks like mine is right on target. High 40's when cold and at idle. About 49 to 53 while at highway speed. When warmed up (end of trip) and at idle, low 30's. Google brought me to this Thread.

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

Thats how it is. I have a real pressure gauge installed and the idiot number on the dash is nowhere near accurate.

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.

So does everybody here have a real pressure gauge?
I was waiting for someone to bring up the fact that the oil pressure readings were just a simulator and have nothing to do with real numbers.

I love how our dash looks advanced, yet it is just a board of idiot lights. I hope the coolant temp gauge is accurate. Such is life...the people of America become dumber so the auto makers move with that trend.

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.

When they switched to the dummy light for the oil pressure gauge everyone commented about it. I think it was back in 2005 or even earlier. I can't remember but I think my 3rd gens had it. It factors in the engine coolant temperature and then behaves like you'd "expect" the oil pressure gauge to -- giving higher readings when cold at higher RPM's, dropping a little lower after fully warmed up at idle, etc...

They actually went to EFFORT to make it simulate the behavior you would want to see when in reality all it's good for is reporting if you have NO oil pressure.

The coolant temp, trans temp, etc... are all real sensors.

I stand corrected, sir! You are correct in stating other engines could use 2 wire sensors which are actual transducers...however, ours are not.
