We were level at FL400 when we received an ENG 3 OIL PARAM ABNORM AMBER CAS message. We followed the checklist for ENG 3 OIL PARAM ABNORM and as we were running the checklist; we received the ENG 3 OIL TOO LO PRESS CAS. This had us run the ENG 3 SHUTDOWN checklist; which we performed as we requested clearance to return to ZZZ with no incident.
Falcon 7X First Officer reported having to shut down the #3 engine inflight to resolve CAS messages received for the #3 engine. An air turnback was performed and a precautionary landing was made.
