Routine oil system maintenance tasks include:

• A. Filtration, level checks, oil quality analysis (viscosity, water content), and keeping the oil cooler clean.
• B. Overhauling the compressor.
• C. Replacing the turbine with a new one.
• D. Painting the oil tank.

Answer: (A)

Routine oil system maintenance centers on keeping the lubricant clean, properly leveled, and in good condition to protect bearings and ensure effective cooling. Filtration removes particulates that cause wear; level checks ensure there is enough oil for proper lubrication and heat dissipation; oil quality analysis (viscosity and water content) monitors whether the oil still performs correctly and detects degradation or moisture that can shorten life or cause corrosion; keeping the oil cooler clean preserves heat-transfer efficiency and prevents oil overheating. The other options describe major repairs or cosmetic tasks not part of regular maintenance, such as overhauling the compressor, replacing the turbine, or painting the oil tank. These routine checks and duties collectively help maintain reliability and prevent failures.
