When using inventory control, you should use a gauge stick or tank monitor to determine the amount of product in the tank ______.

• A. Every week
• B. Every month
• C. Every day your facility dispenses and/or receives fuel
• D. Only when there is a leak

Answer: (C)

Regular, immediate inventory measurement is essential in inventory control. Using a gauge stick or tank monitor to determine how much product is in the tank every time you dispense or receive fuel keeps records up to date and accurate. This frequent checking helps you reconcile purchases, deliveries, and sales exactly as they happen, so you can spot discrepancies, losses, or leaks quickly and take corrective action. It also supports timely reordering and prevents stockouts or overfills, while aiding regulatory and safety compliance.

Checking only weekly or monthly leaves large gaps where losses or leaks can go undetected, and measuring only when there’s a leak misses the routine monitoring that keeps inventory trustworthy.
