If you top up from the engine sump capacity to the total oil system capacity, how many quarts would you add?

• A. 1 quart
• B. 2 quarts
• C. 3 quarts
• D. 4 quarts

Answer: (A)

The amount to add equals the difference between the total oil system capacity and the sump capacity. The sump is the oil that sits in the engine crankcase, while the total oil system includes oil in the cooler, lines, and other components. For this aircraft, the sump holds five quarts and the total oil system capacity is six quarts, so you would add one quart to bring the system up to full. Always verify exact capacities in the current POH for your engine and recheck the level after the oil has settled, to avoid overfilling.
