1. Introduction to Engine Oil:
1.1 Critical Functions of Engine Oil:
Engine oil is not a mere lubricant; it’s a multifunctional fluid that performs the following key functions:
- Lubrication: Reduces friction between moving parts.
- Cooling: Absorbs and dissipates heat generated during engine operation.
- Cleaning: Suspends and carries away contaminants and debris.
- Sealing: Forms a protective film to prevent leaks and maintain proper compression.
1.2 Viscosity and SAE Ratings:
Engine oils are characterized by viscosity, a measure of the oil’s resistance to flow. The Society of Automotive Engineers (SAE) assigns viscosity grades to oils, such as 5W-30 or 10W-40, indicating the oil’s flow characteristics at different temperatures.
