High Oil temperature

[RubyRecon]

My 392 oil temperature runs around 235 degrees just running around town. Does that seem high ? Water temp is usually in the low 200s.

Other will chime in for sure.
For me start and stop always make the oil more hot that an steady drive.
Never reached that temperature but I'm not in the same context as you.
In any case max I have see is around 220F

This other thread says that is normal

235 is a little lower than you want. Oil needs to get moisture out and a good 250° for a little bit will get it out. Oil starts to break down over 300°. So you have lots of room. Especially 0w40…

Probably the Aux battery.

Normal. Mine is ranging between 220 and 240 constantly daily driving, summer or winter. It goes a bit higher in off-road + mode.

Thats ridiculous. You don't need 250 degrees to get the moisture out. A long highway drive at 199 will do it just fine.

I wonder how the water boils out at lower than its boiling point…. But that is just science, in today’s society science takes a backseat.

Put a pot on the stove and heat it up to 190 degrees. Now place a couple of drops of water in it. Or even a couple spoonfuls. Come back in a bit and see the water gone. Water does not need to reach boiling point to evaporate. A good long highway trip at 190 degrees will keep the moisture down in the oil.

Put a pan on the stove with motor oil in it. Put water in the motor oil and heat to 190, the water will never come out off the oil.

But all this is moot since the 392 almost always get above 220 when doing anything. Mine runs 240-250 on every drive even at -30°f…

If that is the case, then I am wrong. I have read otherwise, but who knows if what I read was correct? In any event, thanks for the info! Have a great day!

Completely normal. Don't worry about it. Drive it. Enjoy it.

Thank you everyone. My 2020 with a 2.0 turbo very seldom gets over 220degrees.
As far as having to be above 212 degrees to remove moisture, I am pretty sure when the oil is squeezed between the cylinder walls and pistons, etc, it spikes and then cools while returning to the oil pan.
