However, using the wrong type of oil can lead to various issues, such as oil leaks, engine overheating, reduced mileage, and even engine damage. This article explores the importance of engine oil, its functions, the benefits of using the right oil, and the consequences of using the wrong one.

What Is Engine Oil?

Engine oil or motor oil is a lubrication liquid used in automobiles to reduce friction between the components and improve its function. It is derived from natural and synthetic oil in which some additives are used to improve its performance. It also helps in regulating the temperature of your engine and prevents the deposition of harmful elements within the engine. You need to change the engine oil regularly to maintain the efficiency and durability of the engine to make it have a problem with life. 

What Is The Role Of Engine Oils?

Engine oil plays a crucial role in minimizing friction, reducing wear and tear, dissipating heat, resisting corrosion, keeping engine components clean, sealing piston rings, and removing contaminants. These functions are essential for ensuring the longevity, efficiency, and reliability of an engine. Regular maintenance, including oil changes, is key to preserving engine health and performance.

What Are The 7 Functions Of Engine Oil?

Minimized Friction

Engine oil acts as a lubricant, reducing friction between moving parts within the engine. Creating a protective layer ensures smooth operation and prevents excessive wear and tear on crucial components, such as pistons and crankshafts. This helps to prolong the lifespan of the engine and maintain optimal performance.

Reduced Wear and Tear

One of the primary functions of engine oil is to minimize wear and tear on engine components. By providing lubrication, it prevents metal-to-metal contact, which can lead to damage and deterioration over time. This ensures that the engine operates efficiently and extends its longevity, saving on repair costs in the long run.

Heat Dissipation

Engine oil also helps in dissipating heat generated during engine operation. By absorbing and transferring heat away from critical components, such as the pistons and cylinders, it helps to maintain the engine’s operating temperature within the optimal range. This prevents overheating and potential damage to the engine.

Corrosive Resistance

Engine oil forms a protective barrier against corrosion and rust formation on metal surfaces. This is particularly important in preventing damage to engine parts exposed to moisture or harsh environmental conditions. By not allowing corrosion to happen, it helps to preserve the integrity of the engine and ensures reliable performance over time.

Clean Engine Components

Another vital function of engine oil is to keep engine components clean by trapping and suspending dirt, debris, and contaminants. This prevents them from accumulating and causing damage or blockages within the engine. Regular oil changes help to maintain cleanliness and ensure smooth operation.

Piston Ring Sealant

Engine oil helps to seal the gaps between piston rings and cylinder walls, preventing compression leaks and maintaining optimal engine performance. This ensures proper combustion and prevents loss of power and efficiency.

Contamination Removal

Engine oil also serves to remove contaminants and impurities that accumulate within the engine over time. By capturing dirt, metal particles, and combustion by-products, it prevents them from circulating and causing damage. Regular oil changes are essential to flush out these contaminants and maintain engine health.

What Are The Benefits Of Using Engine Oil?

Fuel Efficiency (Mileage)

Using high-quality engine oil contributes to improved fuel efficiency by reducing internal friction and minimizing energy loss within the engine. Proper lubrication ensures that engine components move smoothly, requiring less energy to operate. This efficiency translates to better mileage for vehicles, ultimately saving fuel and reducing overall fuel costs.

Engine Protection

Engine oil provides essential protection to internal engine components by forming a lubricating film that reduces wear and tear. High-quality oils contain additives that shield against corrosion, oxidation, and deposit buildup, extending the life of critical engine parts such as pistons, bearings, and crankshafts. This protection is crucial for maintaining engine performance and preventing costly repairs.

Reduced Drag And Friction

One of the primary functions of engine oil is to minimize friction between moving parts. By reducing friction, engine oil helps to decrease drag on the engine, allowing it to operate more smoothly and efficiently. This reduction in drag not only enhances performance but also contributes to fuel efficiency by requiring less energy to overcome frictional resistance.

Better Performance in all Weather Conditions

Engine oils are formulated to perform optimally across a wide range of temperatures and weather conditions. In cold climates, high-quality oils maintain their viscosity, ensuring easy engine startup and adequate lubrication during cold starts. Similarly, in hot environments, engine oils remain stable, providing consistent lubrication and protection against heat-induced wear. This versatility ensures reliable engine performance regardless of weather conditions.

Keeps Engine Clean

Engine oil plays a vital role in keeping the engine clean by carrying away dirt, debris, and combustion by-products. Special additives in engine oils help to suspend contaminants, preventing them from settling on engine components and forming harmful deposits. Regular oil changes ensure that the engine remains clean and free from sludge buildup, promoting optimal performance and longevity.

What Happens If Wrong Oil Is Used On Your Engine?

Oil Leaks

Every type of oil has its respective viscosity, and when you use a different oil with a different flow rate it causes oil leaks. You can notice oil leaks under your vehicle when parked. Sometimes the age of your vehicle also plays a crucial role, as older vehicles need thicker oil to seal and protect the engine. While new vehicles are designed for thinner engine oils. Oil leaks are very messy and difficult to clean.

Engine Overheating

When you don’t use the recommended oil for your engine, it starts to overheat. It is because other than lubrication, it also absorbs heat from your engine to stop overheating. 

Using the wrong engine oil will cause instability in the balance of temperature. If the oil that you used has a high thickness, the resistance becomes bigger and more heat is generated.

Reduced Mileage

If you are using a different oil from before on your vehicle you can feel its fuel economy dropping down. Oil with high viscosity requires a large amount of energy to be pumped, leading to more fuel consumption. Also to overcome the resistance of the oil in your engine fuel is used. 

As some amount of fuel is used to just pump the engine oil around, the mileage of your vehicle drops down when you use unsuitable oil for your engine. Changing to a moderately thinner oil can improve fuel economy, but better get suggestions from an expert before getting oil for your engine.

Engine Damage

Using the wrong oil will of course damage your engine, as it is not properly lubricated and causes a lot of heat. The mechanical parts being in contact without lubrication causes wear and tear to the engine parts. The effect might be very small but over time it will make your engine fail, reducing the engine life of your vehicle.

How Important It Is To Change Engine Oil?

You need to change your engine oil regularly at constant intervals, like the number of kilometres you have ridden your vehicle. By changing engine oil regularly you can improve your engine’s performance and extend its lifetimes. This will also help your vehicle attain its peak mileage. Once you change the engine oil, you can feel the engine running smoother than before. 

Please consider consulting with an expert to choose the right type of engine oil that is perfect for your vehicle. Because using the wrong oil has its causes that will make it difficult for vehicles to perform.

Conclusion

Regularly changing engine oil is essential for maintaining engine health, performance, and longevity. By using the correct type of oil and adhering to recommended maintenance intervals, vehicle owners can ensure optimal engine function and prevent costly repairs. Consulting with automotive experts can help in selecting the right oil for specific vehicle requirements, ultimately contributing to smoother operation, improved fuel efficiency, and extended engine life.
