Which lubricant requirement helps maintain temperature?

• A. Cool
• B. Clean
• C. Seal
• D. Reduce Friction

Answer: (A)

The key idea is how heat is managed in a lubricated system. Keeping things cool means the lubricant can absorb heat from moving parts and carry it away, helping to prevent overheating and maintain a stable, safe operating temperature. When the oil stays cool, its viscosity stays in the right range, reducing the chance of breakdown or wear as loads and speeds vary. While clean oil, proper sealing, and reduced friction all support overall reliability, they don’t directly address removing heat to control temperature the way a cooling lubricant does.
