Started climbing from 2500 ft. to 4500 ft.; stopped at 2900 ft. to clear bravo shelf; resumed climb with full power; fuel pump on; mixture top of green; 30 seconds after we called oil pressure indicator was below 48-49 PSI and in the yellow; then had Crew Alert System (CAS) Message; leveled at 4400 ft.; looked for an alternate airport; we called ZZZ; headed that way; descending to 2500 ft. at 600 FPM; descent stopped at ~3100 ft. it seemed on its own; instructor took controls; oil pressure dropped to 2 PSI and stayed at 8% power RPM went to 2800+; oil temp went to 200+ and CAS Message Annunciation. We experienced engine roughness and heavy vibrations. Picked a road next to a field to land; too low for Cirrus Airframe Protection System (CAPS) by that time.
