Oil temp running high.

In my 12.7, my oil temp is usually always 5 degrees more than coolant temp, and always has been for the 6 years I've had this truck. It stays about 200 unless pulling a steep grade.

 

There is nothing wrong with your oil temperature.

 

+1, oil temp is always hotter than coolant. 200-210 degrees or so, normal.

 

On my 06 cat acert it runs 205 15deg more than my coolant

 

Like they said, anything around 200° is normal, when the engine is working! And also you don't won't oil temp to run to low either, then it won't boil off moisture and condensation that forms in the crank case from the temp changes.

 

My cummins isx normal temp when cruising 220 and coolant 185
I wouldn't worry

 

My Cat must be weird. Oil and water temp are about the same. Actually oil temp always runs at 175* on the gauge while the water temp shows from 188* to 192* on CAT information display. I imagine the real oil temp is right with the water temp. On a hot day oil can go as high as 200* and on cold days it will drop down to 150*, and start consumining oil as well down that low.. 200-215* oil temp sounds normal for egr engines in general...
