When making entries in the Oil Record Book, all quantities should be __________.

Correct Answer: Option C — consistently recorded through the Oil Record Book in one specified unit (gallons, barrels, cubic meters)

Consistency in units is mandatory for accurate record-keeping and regulatory auditing. Whether using cubic meters, barrels, or gallons, the chosen unit must remain uniform throughout the Oil Record Book to prevent errors during inspections and ensure that the Chief Engineer’s entries are clear, verifiable, and legally defensible.
