Narrative:
Takeoff and climb out through ten thousand feet was normal. Upon passing 16;000 feet; the flying first officer noticed the left engine oil quantity had gone to '0'. At that moment; we began to analyze the situation and contacted dispatch to bring them into the loop. Within a few minutes; the pressure went to approximately 50 psi. We ran the irregular procedure for engine oil press checklist; shut the engine down and dumped fuel and landed with no further issues. One issue of concern that came up during this incident was with dispatch. They were slow to respond with the appropriate information for our landing distance for a flaps 20 single-engine approach. Having this information readily available in an emergency situation is very important.
