It does. I can crank up the timing to make it hotter but... MPG drops out badly.. 15 to 17 MPG. Outside temps in the 10 to 20*F up here. Thermostat is closed and holding barely 192 to 195*F. The lower coolant hose is COLD to the touch. 

 

More timing the hotter the oil temp. More retard the cooler the oil tremp. This photo was a older tune my recent tune is right at 20* at 2k RPM. Remember Trans is the engine oil.

250 miles daily trips. This is my standard from New Meadows to Ontario, OR runs and back home. Photo is dated 12/31/2019 (Tuesday)

then I would say your temperature sender is reading more of the temperature of the filter head housing and not the oil. After about 30 miles the oil temperature should match coolant and up from there is based on efficiency

Sorry. I don't know what to say. I've check it many times and it correct. Remember 24V are NOT CR engines. Might hold true for your old truck... Umm the oil is flowing through that port. That is true oil temp from the oil cooler. If not my turbo would sure hate life if the oil isn't moving.20200131_053155.jpg

What I said holds true regardless. If the temp sender is reading the temp of the entire unit and not the tip of the sensor it will read low. That looks like what is happening for you. 
 

The oil actually gets hotter on these engines with the piston and head heat and then the coolant brings it back down. The oil is exposed to more heat and has less cooling. 

 

It’s not 24V vs CR, it’s general engine operations. Oil temps operate at or above coolant temps without external oil coolers.

We can change sensor but it not going to change the temp. I can measure the temp with my IR gun and still be the same. I cant make it hotter being the oil temp is still the oil temp.

You just proved my theory. If the IR gun reads the same temp your reading oil filter housing temp and not actual oil temp. That’s why it’s cold. 
 

The filter head will always be colder than actual oil temp. 

It should still give you a good relative indication, it’s just not actual oil temperature. It’s probably about 30° low.

Still doubt that being the sensor is INSIDE the oil. The sensor the probe tip is nearly 3/4 long inside the oil. The oil is MOVING past the sensor and oil filter into the turbo. 

 

Now I could see you point like in transmission application where people put the sensor in the accumulator piston and the fluid is not flowing. This is in a flowing oil galley and the main oil feed to the turbo. 

 

So I still doubt your comments being the fluid is moving into and out of the oil filter.

Mike, I found the 200 t stat I pulled out of my 2012 in favor of a 190. It was good when I pulled it and I’ll send it up to you if you want it

Sure.

All this coolant temp issues and my sensor goes on the fritz last Thursday afternoon. By the time i got halfway home Friday it really wacked out. Put a spare in this morning am and its working just fine again.

I typically see the same temps John did with his 05 in my 14. I have seen temps as high as 245 pulling a very long grade with 16k in tow. 

I'd be interested to see what my 2nd gen does, but don't have a sensor to install.

Mike, tracking shows that t-stat delivered yesterday. I sent it in a very discrete valentines day padded envelope.:lmao:

Ummm... Not seen. Eileen was home all day unless its in the mail that my neighbor picks up. I'll look today.

 

As for returning back to the oil temp the lowest I got was running +2*F outside, winter front, and the oil temp was 162*F and so was the oil filter measured with IR gun. On the way home in 40*F weather it was 171*F maxed out climbing 6% grade. I've even bumped the timing up trying a tweak in my winter tune. Coolant still running 192*F to 195*F constantly. Double check and triple checked that temperature is absolutely correct. The only thing I can say is this is the oil AFTER the cooler. Being the radiator on the suction side is cool to the touch. But yes that temperature shown by the Quadzilla is 100% correct.
