Just curious what everyone is seeing driving your trucks empty. Are these normal temps? My oil temp is around 200.
That 198° on the far right is your transmission temputure the 192° is coolant you do not have the engine oil temp showing on your display in the picture. The trans has a thermostat its supposed to run that hot. You can or atleast could display the engine oil temp your just not on the right screen to see it.

yes I know how to get to the screen with the oil temps. And at the time I took the pic it read 199.
Thanks guys just curious if these numbers were accurate empty. Towing 20k pounds in this Texas heat I've seen coolant temps at 225, trans temp 240-245, and oil temps 240-245.
On flat highway going 65 mph empty my oil temp from the engine info screen shows 203. It will go up from here due to hills or load. I have had the coolant temp jump to numbers a couple times towing up larger grades. The other thing I have noticed is that once my oil temp gets to about 214 or 216 the engine is working hard enough that the exahast is hot enough to do a passive regen as well. There is a grade here in Northern Cal that comes up from the coast that is steep enough and long enough that the oil will get to 216 or 218 with no trailer behind the truck.
Metals function better and last longer when exposed to the right amount of heat. In the old days, they kept the heat down because the gasket materials and seals couldn't take the heat.... Not because the metals couldn't. Metal likes heat.
Any former machinists in here? Try cutting, turning or grinding hot metal. It's why machining tools almost always have coolant running over them. Hot metal is tough and strong -- Up to a point, course. 1,000 degrees ain't real good for it but 250 degrees F don't bother it none.
Plus the fact that the old Dino oils would turn into a pile of ash and sludge at 250 degrees. Most of their additives would be permanently destroyed. Which is why, if you ever get your engine really, really hot, you want to change the oil. The newer synthetics don't mind it too much at all. They kinda dig it. But still, if you get your engine up over 250 degrees, I'd probably change out synthetic oil, too. At 250 degrees, all the additives in dino oil is gonzo, so you're left with whatever base stock they started with -- Often about the consistency and lubricating qualities of baby oil

Is this before or after the new oil pan?
My empty numbers are pretty much the same as yours.

You're totally correct, 250F isn't much at all to the metals involved...but it was never the total temp that does damage here anyways, its the heat cycling that will do it. 70F - 250F - 70F - 250F over and over and over will eventually fatigue the metal from the expansion/contraction.
