If oil is in the 402-499, 601-699 range and OAT is -35°C, the required quantity is:

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

Answer: (B)

Temperature affects oil volume, so the quantity you set from the maintenance chart depends on both the oil’s current level range and the ambient temperature. When oil is in the 402-499 or 601-699 range and the outside air temperature is as cold as -35°C, the oil contracts and the dipstick reading underestimates the actual amount the engine will need once it warms up. The cold-weather instructions for this oil-range condition specify a target of 14 quarts to ensure the correct level after startup and warming. Filling to 16.5 quarts would risk overfill in cold conditions, while 12 quarts or 10 quarts would be insufficient for proper operation when warm. So the 14-quart quantity is the appropriate cold-weather requirement.
