For oil quantities in ranges 402-499 and 601-699, if OAT is at or above -30°C the required quantity is:

• A. 14qt
• B. 16.5qt
• C. 12qt
• D. 10qt

Answer: (A)

The main idea is that oil quantity is chosen from temperature-based bands. When outside air temperature is at or above -30°C, you use the smaller quantity that sits in the 402-499 band, which corresponds to 14 quarts. Oil expands with temperature, so in warmer conditions you start with a smaller amount to end up at the correct level after warm-up. The higher quantity (16.5 quarts in the 601-699 band) would be used for colder conditions where the oil is thicker and the level would be lower when cold. The other numbers fit other temperature ranges, not this one. So, under OAT ≥ -30°C, the required quantity is 14 quarts.
