Narrative:

At approximately 20500 ft the #1 low oil pressure light illuminated, checked oil pressure gauge, approximately 20 psi, oil quantity was zero and oil temperature was normal (after closing #1 throttle, the oil temperature did go into the yellow band). We accomplished the appropriate checklists, informing ZTL of the situation and stopped the climb at 21000 ft and requested to return to clt. ATC cleared us direct to clt and a lower altitude. Switched to cit approach control. Gave them the situation and asked for the emergency equipment to be standing by. Made an uneventful single engine approach and landing.
