Functions of Engine Oil: Making a Difference in Your Car’s Performance

0 Comments

Good engine oil is the lifeblood of your vehicle since how your car performs depends on which oil you use. Oil is not only a commodity but an engineering component that fuels the performance of your car’s engine. Having a suitable engine oil provides several functions to your engine and protects its components from any rust, corrosion, or harm. But these oils also come in different grades, and you must get the right one to ensure that your engine performs its best at any temperature. As such, we have listed below all the ways that engine oil helps your vehicle and how you can get a great quality lubricant. 

How Does Engine Oil Make a Difference for Your Vehicle?

Following are all the ways that engine oils add value to your vehicle. 

Protection 

One of the primary things that engine oil does is protect the components. It prevents them from rubbing against each other, which might cause them to break down in a shorter time. The lubricant creates a protective film to ensure that the high-stress areas of your vehicle do not affect each other and get eroded. The rust and corrosion inhibitors of these oils protect against any wear and tear as well. 

Reducing Friction

Engine oil reduces metal-to-metal contact and reduces friction by forming a protective layer around the engine’s running parts. This ensures that the metal parts are in optimal condition and deliver the best performance. 

Coolant

The engine oils with coolant features keep the running parts of the engine cool at all times. It prevents the deterioration of the engine and energy loss caused due to excess heat. 

Removing Impurities

Most engine oils come with additives that remove any deposits and impurities from the oil, which keeps the engine’s components clean. The lubricant also protects it from any grave damage. The engine oil keeps all the removed grit, dirt, unburned carbon, metallic materials, and other impurities suspended to ensure that the filter can properly absorb them. 

Acting as a Gap Filler

The cylinder and the piston of the engine have a rough space between them, where the engine oil acts as a gap filler and helps improve the engine’s performance and efficiency. 

Saving Fuel 

An engine oil boosts the efficiency of your entire vehicle through optimal lubrication. This, in turn, reduces fuel consumption and leads to the oil’s contribution towards environmental protection and emission reduction. 

How to Pick the Right Engine Oil?

Now that you know all about the functions of an engine oil, you can pick the right one for your vehicle. However, you must consider the points below when choosing the lubricant. 

Viscosity

Viscosity is a fluid’s resistance to flow, and most of the lubricant’s viscosity is rated based on its thickness at zero degrees fahrenheit. Engine oils become runnier and thinner the more they heat up, but they thicken as they cool down. Thicker oil gives a better lubrication film between the moving parts and better seals the important parts of an engine. One will need different oil viscosity when using their vehicle in different temperatures. 

Understand the Labels

Every oil container comes with labels, and the API doughnut on the right side will tell you whether the oil meets a current service rating. The oil container also comes with the SAE or Society of Automotive Engineers viscosity number, which informs you whether the car gear oil has passed the resource-conserving test. The container will also have a starburst symbol on the left, indicating that the oil has been through the service tests. 

Conclusion

Picking the right kind of fluid is necessary for your automobile, and you can get the best lubricant by ensuring that it is suitable for your car’s engine. You can determine such suitability by going over the user manual provided by the manufacturer and also considering the model and make of your car. You can also check whether an automatic transmission oil or ATF oil is suitable for your vehicle since it ensures the proper protection, performance, and operation of the automatic transmission. Ultimately, you know your vehicle the best, and ensuring the quality of the engine oil is your responsibility. If you pick the right fluid for your engine, then it will deliver unparalleled performance.
