1. Engine Lubrication: Oil lubricates the engine’s moving parts, reducing friction and preventing wear and tear. Over time, oil breaks down and becomes less effective at lubricating, potentially leading to engine damage if not changed regularly.
  2. Engine Cooling: Oil also helps to cool the engine by carrying heat away from the combustion chamber. As oil ages, it loses its ability to dissipate heat efficiently, which can result in overheating and engine failure.
  3. Contaminant Removal: During operation, oil picks up dirt, debris, and other contaminants from the engine. Regular oil changes remove these impurities, preventing them from building up and causing damage to the engine components.
  4. Improved Fuel Efficiency: Fresh oil reduces friction within the engine, allowing it to operate more efficiently. As a result, regular oil changes can help improve fuel economy and prolong the life of the engine.
