Yes, but only relatively small quantities of the oil.

Also the oil is not cooled down as well as the water.
It's not necessary since the oil works fine in much higher temperatures.
In my Audi the oil is cooled (and preheated for that matter) close to the
oil filter.
At certain speeds (revs) the oil and water are both 90 degrees Celsius.
