Narrative:

During the final stage of climbout it was noticed that the number one engine oil temperature was unusually high. I decided to request with ATC to level off at 13;000 ft (assigned altitude 15;000) in an attempt to increase airflow and reduce oil temperature but that was of no avail. Dispatch and maintenance were brought into the loop and the decision was made to return to land. Once the aircraft initiated the descent and the power reduced to maintain a speed restriction required by a cdl the oil temperature returned into the green arc with no further abnormalities in oil temperature until landing when the oil temp began to rise again. At that time the #1 engine was shutdown anyway for fuel conservation via single engine taxi.
