Final answer:
Engine oil quantity is measured in quarts. Normal range is 0 to 20 quarts, but caution must be exercised if it falls below 37 quarts. If it is less than 37 quarts, a 781A write-up is necessary within 40 minutes of engine shutdown.
Step-by-step explanation:
Engine oil quantity is typically measured in quarts.
In normal conditions, an engine may require anywhere from 0 to 20 quarts of oil. However, it is important to exercise caution if the oil quantity falls below a certain threshold. If the oil quantity is less than 37 quarts, it is necessary to write up a report, known as a 781A, after the engine has been shut down within 40 minutes.
