Essential Information for Automotive Maintenance

Introduction
Engine oil is a crucial component in the
operation and maintenance of internal combustion
engines. Beyond lubrication, engine oil performs
several vital functions it helps to cool the
engine by dissipating heat, cleans the engine by
carrying away contaminants and deposits, protects
against corrosion by creating a protective
barrier on metal surfaces, and aids in sealing by
filling gaps between engine components.

Types of Engine Oil

• Mineral Oil Traditional, derived from crude oil.
• Synthetic Oil Man-made, superior performance.
• Semi-Synthetic Oil Blend of mineral and
  synthetic oils.

Functions of Engine Oil

• Lubrication Engine oil reduces friction between
  moving parts, minimizing wear and tear.
• Cooling Absorbs and dissipates heat.
• Cleaning Removes contaminants and deposits.
• Protection Prevents corrosion and wear.
• Sealing Helps seal gaps between piston rings and
  cylinder walls.

5
Viscosity and Grades

• Explanation of Viscosity Thickness of the oil,
  important for performance in different
  temperatures.
• SAE Ratings e.g., 5W-30, 10W-40. W stands for
  winter lower numbers indicate better performance
  in cold temperatures.

Checking and Changing Engine Oil

• How to Check Oil Level Use dipstick check
  regularly.
• When to Change Oil Follow manufacturers
  guidelines, typically every 3,000-5,000 miles or
  3-6 months.
• Signs of Needing Change Dark, dirty oil engine
  noise check engine light.

Conclusion
Engine oil is indispensable for the optimal
performance and longevity of internal combustion
engines. By providing essential lubrication,
cooling, cleaning, protection, and sealing, it
ensures that engines run smoothly and
efficiently.
