Why Does My Engine Need Oil?

Oil is often referred to as the lifeblood of an engine and for good reason. Do you want to know exactly why? Keep on reading so you can find out and make sure to check your engine level after you finish the article!

1. Lubrication

One of the primary functions of engine oil is to lubricate the various moving parts within the engine. As the engine runs, numerous metal components, such as pistons, crankshafts, and camshafts, move rapidly and create friction. Without proper lubrication, these metal surfaces would grind against each other, leading to excessive wear and damage. Engine oil forms a thin protective layer between these components, reducing friction and heat generation, and ensuring smooth operation.

2. Heat Dissipation

Engines generate a significant amount of heat during operation. The oil circulating within the engine helps in dissipating this heat. It absorbs heat from the engine's components and carries it away, preventing overheating. By regulating the temperature, the oil helps maintain the engine's efficiency and prevents potential damage that can occur due to excessive heat.

3. Contaminant Removal

Engine oil acts as a cleaning agent, capturing and carrying away dirt, debris, and combustion byproducts that accumulate inside the engine. Over time, these particles can become abrasive and cause damage to the engine's components. The oil's additives and filtration system trap these contaminants, preventing them from circulating and causing harm. Regular oil changes ensure the removal of dirty and degraded oil, replacing it with fresh oil to maintain optimal engine performance.

4. Corrosion Protection

Engine oil contains additives that provide protection against corrosion and rust. These additives create a protective barrier on metal surfaces, preventing the formation of rust and corrosion caused by moisture and acidic byproducts of combustion. By keeping the engine's components clean and corrosion-free, the oil helps prolong their lifespan and ensures reliable performance. 

5. Seal and Gasket Maintenance

The engine's seals and gaskets play a crucial role in preventing oil leakage and maintaining proper compression within the combustion chamber. Engine oil helps keep these seals and gaskets lubricated, soft, and flexible. It prevents them from drying out, cracking, or becoming brittle, ensuring a proper seal and preventing oil leaks.
