What was found
ON PREFLIGHT RIGHT ENGINE WAS SHOWING 3.5QTS LOW. I PUT APPROX 1.75 QTS OF OIL IN RIGHT ENGINE TO BRING IT UP TO 1.75 LOW ON DIPSTICK. THE R ENG TEMP WAS A BIT HIGH BUT IN THE GREEN FOR THE FIRST HOUR PLUS OF THE FLIGHT. IT STARTED CREEPING UP TOWARDS THE YELLOW ARC THEN CAME BACK DOWN INTO THE GREEN ARC. WE REDUCED POWER TO SEE IF THAT WOULD HELP KEEP IT IN THE GREEN ARC. EVENTUALLY IT WENT INTO THE YELLOW THEN JUST BELOW THE RED. WE DECIDED TO SHUT THE ENGINE DOWN AS A PRECAUTIONARY MEASURE. WE DECLAIRED AN EMERGENCY AND LANDED UNEVENTFULLY IN KIDA. PICTURE IS JUST BEFORE SHUTDOWN.
