Narrative:

Upon initial climbout from the class D airspace we experienced engine roughness coupled with a red line oil temperature and no oil pressure indication on the engine gauges. In order to preserve the safety of flight we declared an emergency and returned the aircraft to the airport via left traffic into runway xx. There were no issues discovered in preflight and the aircraft had just been flown prior. A run up check was done before receiving takeoff clearance and no issues were discovered. All engine instruments were in the green and the engine ran smoothly. Takeoff and initial climbout had no issues and we were cleared for an instrument departure from runway xx. Once established in the climb the engine started to run rough while the temperature gauge pegged max temperature and oil pressure dropped to zero. At this time we declared an emergency and turned back to the runway for landing.

Title: A DA-20 began running rough after takeoff while the oil temperature increased to maximum and oil pressure decrease to zero; so an emergency was declared; a turn made to the nearest runway; and a safe landing completed.
