1. Friction Reduction: Engine parts such as pistons, crankshafts, and camshafts move at incredibly high speeds and under tremendous pressure. Without proper lubrication, these metal parts would rub against each other, generating excessive heat and friction, leading to wear and tear.
  2. Heat Dissipation: Engine oil helps in dissipating heat generated during the combustion process. It carries heat away from critical engine components, preventing them from overheating and potentially failing.
  3. Corrosion Prevention: Engine oil forms a protective layer over metal surfaces, preventing corrosion caused by moisture and combustion by-products. This extends the lifespan of engine components.
  4. Sealant Maintenance: Engine oil helps in maintaining seals and gaskets in good condition. It prevents them from drying out and cracking, which could lead to oil leaks and loss of pressure.
  5. Cleaning: High-quality engine oils contain detergents and additives that help in keeping the engine clean by trapping contaminants and preventing sludge buildup. This ensures proper functioning of engine components and maintains overall efficiency.
  6. Reduction of Wear: By forming a protective film between moving parts, oil reduces metal-to-metal contact, minimizing wear and tear on engine components. This prolongs the life of the engine.
  7. Fuel Economy: Properly lubricated engines operate more efficiently, leading to improved fuel economy. Reduced friction and smoother operation mean less energy loss, translating to better mileage.
