Min oil quantity for ranges 230-299 and 701-799 is:

Min oil quantity for ranges 230-299 and 701-799 is:

• A. 9.5qt + .5qt per every hour of estimated flight time
• B. 10.6qt
• C. 9qt + .5qt per every hour of estimated flight time
• D. 8qt + .5qt per hour

Answer: (A)

Oil quantity has to cover the engine’s lubrication needs for the planned flight time. The baseline of 9.5 quarts provides enough oil for startup, warm-up, and typical operations, while adding 0.5 quart for every hour of estimated flight time accounts for ongoing oil consumption during the flight. This combination ensures you won’t run low on oil over longer trips. For example, a 1.5-hour flight would require 9.5 + (0.5 × 1.5) = 10.25 quarts. The other options either omit the hourly increase or use an inappropriate base amount, which could leave you short on longer flights.
