Aircraft
At FL350 we noticed the right engine oil quantity was four quarts and going down after being even. All other indications were normal. Not knowing if it was an indicator malfunction or an actual oil loss we pulled out the QRH talked about suitable airports and informed Dispatch. The engine oil temperature kept increasing and the oil pressure getting lower. I declared an emergency and headed for ZZZ. In accordance with the QRH I shut down the right engine. We requested the equipment and prepared for a single engine landing. We informed Dispatch and the flight attendants and made a PA announcement. I did not feel we needed to prep the cabin. After landing; the fire department checks the brakes for temperature readings.
After arriving a little late; we did a quick turn and left only four minutes late. Aircraft was in cruise flight when it was noted oil quantity was four quarts in the right engine. Left was still indicating eleven quarts as were both engines in cruise on previous leg. By the time the Captain had sent a note to Maintenance; oil had dropped to zero quantity. We declared an emergency and decided to land at ZZZ which was directly below us. We continued to monitor oil pressure; which began to slowly decrease. We pulled out the low oil pressure check list and then the severe engine damage checklist; to shut the engine down before the engine was damaged. Captain notified Dispatch; flight attendances and passengers of diversion. We briefed approach and single engine go around. I continued to fly aircraft to runway in ZZZ and emergency equipment followed us to a safe location. They inspected brakes and found them cool enough for us to proceed to gate.
A B757 flight lost right engine oil quantity at FL350; followed by loss of oil pressure and rising temperature. The engine was shut down and the flight diverted to the nearest suitable airport.
