Engine Oil is a vital lubricant used in vehicles to ensure the smooth functioning of engines. It reduces friction between moving parts, prevents overheating, and protects the engine from wear and corrosion. Engine oil also helps in cleaning the engine by suspending dirt and metal particles, improving fuel efficiency, and extending the engine’s lifespan. Available in various types—synthetic, semi-synthetic, and mineral oil—it is selected based on the engine’s requirements, climate, and driving conditions. Regular oil changes are essential to maintain engine performance and ensure long-term reliability.
