What do you use to preserve a fuel component?

• A. MIL-PRF-6081 Grade 1010 oil
• B. Water
• C. Gasoline
• D. Mineral oil

Answer: (A)

Preserving a fuel component means applying a protective oil that hinders corrosion, varnish, and moisture-related damage when fuel systems are stored or out of service. MIL-PRF-6081 Grade 1010 oil is the standard preservative specified for this purpose, providing a light film that coats metal surfaces and helps prevent corrosion and deposits in fuel-system components such as pumps, valves, and lines. The other options don’t serve as a prescribed fuel-system preservative: water would promote corrosion and microbial growth, gasoline is the fuel itself, and mineral oil by itself isn’t specified as the fuel-system preservative for aircraft components.
