Narrative:
[We had a] emergency return due to low oil quantity indication after takeoff/overweight landing. Shortly after takeoff; when climbing through about 1;500 ft AGL; the #2 engine oil quantity dropped to 2 quarts; then to 1 quart. Crew decided to make immediate return to land. Emergency declared with ATC; emergency equipment requested to be standing by. A normal landing was made at a landing weight of 146;700 pounds (overweight). During the entire event; there were no other abnormal engine indications; which continued to operate normally. During the approach to landing; the oil quantity slowly increased to 8 quarts. After gate arrival; maintenance serviced engine with 20 quarts of oil and performed the overweight landing inspection. Brake cooling chart was consulted before next departure. Subsequently [we] departed the scheduled destination and engine operated normally. FYI - the 'low engine oil quantity' checklist was removed from the 737 QRH.
