Motor oils are also known as engine lubricants, as their main job is to provide softness to motor engines. These oils are chemically formulated with multiple substances, such as base oils rich with additional elements, particularly antiwear additives, detergents, dispersants, and different grade oils for viscosity index. The primary purpose of using motor oil is to produce lubrication and prevent chafing in the internal combustion engines. Friction is primarily standard on moving parts of the internal engine, and therefore, for long-lasting engines and improved efficiency, lubrication is a requirement for smooth running and function. In addition to that, the lubricants clean the engine from sludge and varnish, which is removed by the additional dispersants and detergent present in the lubricant. The acid produced from the fuel within the engine needs to be cleared off; therefore, the lubricant also neutralizes the acid present in the engine, yielding abrasions and chafing. The detergents oxidize the engine allowing the piston rings to see efficiently, resulting in excessive heat. In addition to that, lubricants are designed and produced to cool the engine, improve the pressure performance and curtail the corrosion of engine parts. The engine parts which are constantly in touch with each other leads to friction resulting in heat and compromising the efficiency and output of the engine. The wear and tear of engine parts can be avoided by constantly giving juice to the engine.
Can I use 5w20 instead of 5w30?
No, it is not recommended to change the oil type for your engine because 5w30 has a higher viscosity than 5w20. 5w20 oil is fairly light oil and is generally designed to work with newer engines. However, sometimes if the manufacturer approves, you can use 5w20 instead of 5w30 because 5w30 motor oil is a suitable choice for hotter climates where thinner oils tend to break down under high temperatures.
If you accidentally put 5w20 instead of 5w30 this will not create a drastic hazard on your engine.
There is a large variety of motor oil products manufactured through different properties and chemicals. The most common type of engine oil is 5W20 and 5W30. The Society of Automotive Engineers has classified and labeled other motor oils based on their viscosity property and are labeled from 0, 5, 10, 15 until 60. Viscosity is defined as the time taken by the liquid to travel and reach its destination. These oils are sometimes used interchangeably; however, there is a significant disparity between the chemical and physical properties; therefore, it is imperative to understand their internal structure before using them as lubricants. The main difference is observed through the concept of viscosity which in simpler words is the thickness of the liquid. If the viscosities of these oils are understood, they can be used in various conditions. 5W20 is most commonly used during winter or colder climates. The number present before W highlights the oil’s viscosity in the winter season, whereas 20 is used to highlight 20 weight oil in warmer conditions. To summarize, 5W20 provides lubrication to the engine like 20 weight oil. It is appropriate to consume in tremendously low temperatures, and subzero atmosphere as the engine experiences less friction to operate the engine. In winters, because of less friction, the engine is less dragged, and therefore this lubricant is ideal because of its viscose property. The viscosity increases with the increase in number therefore, 5W30 is comparatively more viscous and thicker than 5W20. After having a sufficient understanding of the chemical properties of these two categories, it is established that substituting 5W30 in place of 5W20 is not a sensible idea. If the car manufacturing company has particularly highlighted the use of 5W20 oil to the engine, it should remain that way. The less viscose property of the 5W20 engine provides the required efficiency and push to the engine because of its property.
Turning on the engines in freezing conditions requires less viscose or thinner oil to provide the necessary lubrication to operate the engine quickly. Optimal and appropriate fuel efficiency and commendable engine performance are only acquired through adding less viscous lubricant. As the weather changes, the engine is automatically heated up; therefore, 5W20 can no longer serve the purpose of providing optimal performance. It is advised to replace it with 5W30 for excellent performance. 5W20 is more likely to break down in warm climates, consequently increasing the likelihood of engine impairment and weathering. A hundred degrees Celsius, the 5W20 has a viscosity of 8.9, where is 5W30 has a viscosity of 11. Similarly, at 40° 5W20 shows viscosity at 49.8, and 5W30 exhibits it at 61.7. Hence it can be established that heat has a significant effect on the viscosity of engine oils. If you reside in warm temperatures, then it is ideal for keeping 5W30 for regular use. Due to its highest viscosity and thickness, it provides friction and more drag. Because of this, it takes additional time to provide the necessary grease to the engine parts in freezing temperatures. Thicker engine oil is not recommended for freezing temperatures because it will take additional time to flow quickly to the engine components in less a period of time. This will compromise efficiency because of its ability to flow.
Using suitable motor oil for the vehicle’s engine is essential otherwise, the car engine may steer towards damage. Moreover, providing lubrication to the engine is important as it will protect it by preventing the metal parts from forcing towards each other. Overheating is a common process that needs to be tackled before it is too late. Lubrication prevents the metal parts from forcing and grinding against each other therefore adding extra liquid is beneficial and healthy for the engine. They get rid of the acids embedded in the engine giving birth to corrosion, and clean it thoroughly. Silicon oxide naturally accumulated in the engine, which needs to be cleared out as well. Providing lubrication to the engine takes out all the waste, unnecessary litter material, and small particles that impair the engine’s efficiency.
There is no hard and fast rule for replacing engine oil as they are considered flexible. In this situation, both 5W20 and 5W30 can be used interchangeably to protect the car’s engine irrespective of the climate and weather. If car owners are still apprehensive about which oil to purchase then, 5W30 is the right option. It is equipped with strength compared to the 5W20 and has a smooth operational result irrespective of the location’s vehicle company features and temperature. Lubrication is similar to food intake as it provides the necessary nutrients and essential elements to restore it in terms of efficiency. If engine oil has not been replaced for a while, the drivers may experience a bumpy ride. The need for lubrication will be revealed by the car itself through its improper function and ride.
