(CAN) APPROX 20 MINUTES INTO THE FLIGHT, DURING CRUISE AT FL450, THE CREW REPORTED THAT A RED EICAS (L ENG OIL PRESS LOW) MESSAGE POSTED ALONG WITH THE LT OIL PRESSURE INDICATION TURNING RED AND READING 26 PSI. THE CREW FOLLOWED THE AFM CHECKLIST AND SHUTDOWN THE LT ENGINE AND RETURNED TO THE AIRPORT.

THE ENGINE WAS REMOVED AND REPLACED WITH A LOANER AND THE AIRCRAFT RETURNED TO SERVICE. (TC NR 20051212004)
