What are the 5 functions of oil?

The oil system provides lubrication for many components inside a piston engine.

But you might be surprised what else it can do:

Lubrication: One of the primary functions of oil in a car engine is to lubricate moving parts. As the engine operates, various metal components such as pistons, crankshafts, and camshafts rub against each other. Without proper lubrication, these parts would experience excessive friction, leading to wear and tear, increased heat generation, and potentially catastrophic engine failure. Engine oil forms a protective film between these components, reducing friction and ensuring smooth operation.


Heat Dissipation: Oil also helps dissipate heat generated by the engine’s combustion process. As the engine runs, temperatures inside the combustion chamber can soar to extreme levels. Engine oil absorbs some of this heat and carries it away from critical components, such as the cylinders and cylinder heads. Proper heat dissipation prevents overheating, which can damage engine parts and compromise performance.


Sealing: Engine oil plays a crucial role in maintaining proper seals within the engine. Seals, gaskets, and O-rings prevent oil and coolant leaks while also keeping out dirt, debris, and contaminants. A consistent supply of clean oil helps these seals remain flexible and effective, ensuring that the engine remains sealed and free from leaks.


Cleaning: Oil acts as a cleaning agent inside the engine, helping to remove contaminants, dirt, and debris that can accumulate over time. As the oil circulates through the engine, it carries away particles and deposits, preventing them from causing damage or clogging critical components. Additionally, modern engine oils often contain detergents and dispersants that further aid in keeping the engine clean and free from harmful buildup.


Corrosion Protection: Another essential function of engine oil is to protect metal surfaces from corrosion and rust. By forming a barrier between metal parts and moisture or oxygen in the air, oil helps prevent oxidation and corrosion, extending the lifespan of engine components. This protection is particularly crucial in engines that may sit idle for extended periods, such as in seasonal vehicles or machinery.

How does oil get used in a car?

The first and most important job of motor oil is to lubricate the rotating components of an engine, and it must be under a good pressure to do its job. Oil is forced into the space between the bearings making contact with the crankshaft journals and the journals. In a car, oil serves multiple critical functions within the engine. 


First and foremost, engine oil is pumped from the oil pan into various components of the engine to provide lubrication. As the engine operates, metal parts such as pistons, crankshafts, and camshafts move at high speeds and come into contact with each other. Engine oil forms a protective film between these components, reducing friction and wear.

Engine oil forms a protective film between these components, reducing friction and ensuring smooth operation. This lubricating function is crucial for maintaining engine performance, prolonging the lifespan of engine components, and preventing damage or failure due to excessive wear.

Why do we still use oil in cars?

“The primary role of motor oil is to lubricate the insides of your engine to prevent abnormal wear and tear,” says Marshall Castle, an ASE-certified master automotive technician and owner of Chicago Car Care, Inc. Without regular oil changes, friction builds up between the engine’s many moving parts. We continue to use oil in cars primarily for lubrication and heat dissipation within the engine. Oil serves as a crucial component in reducing friction between moving parts, such as pistons, crankshafts, and bearings, thus minimizing wear and tear and prolonging the lifespan of the engine. Without proper lubrication, these metal components would grind against each other, leading to overheating, increased fuel consumption, and ultimately, engine failure. 


Additionally, oil helps to seal gaps between components, preventing leaks and maintaining the integrity of the engine’s internal system. Oil plays a vital role in dissipating heat generated during engine operation. As the engine runs, it produces significant amounts of heat due to combustion and friction. The oil circulates throughout the engine, absorbing heat from critical components and transferring it away to the oil pan, where it can dissipate into the surrounding air. This process helps to regulate the engine’s temperature and prevent overheating, which is essential for maintaining optimal performance and preventing damage to the engine.

How does oil get dirty?

Your engine takes in air in order to function, and that also includes sucking in dirt and debris from the road. Those particles are eventually absorbed by the motor oil, resulting in it getting dirty, which impacts its performance. Here are some things you can do to tell when your oil is dirty enough to need changing. Engine oil becomes dirty through a combination of factors, primarily the normal operation of the engine. As the engine runs, various contaminants are produced, including dirt, dust, metal particles, and combustion by-products such as carbon and acids.


Another factor contributing to oil contamination is the accumulation of moisture. Moisture can enter the engine through condensation or as a by-product of combustion. Over time, moisture can mix with the oil, leading to the formation of sludge and acids, which can degrade the oil’s performance and reduce its lubricating properties. Furthermore, prolonged use of oil without regular maintenance, such as oil changes, can exacerbate contamination levels, leading to accelerated wear on engine components and potential engine damage.
