What type of oil system does a Cessna 172 use?

• A. Dry sump
• B. Wet sump
• C. Hydraulic sump
• D. Flash sump

Answer: (B)

The Cessna 172 uses a wet sump oil system. In this type of oil system, the oil is stored directly in the engine's crankcase and is circulated through the engine components to lubricate them. This setup is simpler and more common in smaller aircraft like the Cessna 172 because it requires fewer components than a dry sump system, which externalizes the oil reservoir away from the engine. A wet sump system is advantageous for general aviation aircraft, as it tends to be lighter and easier to maintain. The design of the Cessna 172's engine allows for effective oil management and lubrication while keeping the system efficient and straightforward.
