Impact of Poor Quality Lubricant?

Harmful effects of poor quality lubricants
Latest update date: February 18, 11

Lubricant, also known as lubricating oil, is an indispensable liquid in the operation of most types of machinery, from vehicle engines to large industrial equipment. So why is lubricating oil so important? Let's find out!

In the modern automotive world, lubricating oil is not just a liquid, but also an essential component that helps the engine operate efficiently and durably. Understanding the role of oil in the engine will help users make the right decisions in maintaining and servicing their vehicles.

The role of lubricants

The five main roles of lubricants include:

  • Lubrication: Oil creates a film between metal parts such as pistons, camshafts and valves, helping to reduce friction and wear. According to research, when the engine is running, the friction between parts can account for up to 50% of the energy consumption. Thanks to oil, this friction is reduced, thereby increasing operating efficiency.
  • Cooling: The temperature inside the engine can reach 200°C during operation. Oil not only helps dissipate heat but also cools the internal parts of the engine, preventing overheating and piston burning.
  • Sealing: Oil acts as a soft cushion between the piston and the cylinder wall, helping to maintain pressure in the combustion chamber and prevent energy loss. This is extremely important to maintain optimal engine performance.
  • Cleaning: During the combustion of fuel, dirt and residue are produced. Oil has the ability to wash away and clean these residues, keeping the engine clean and running smoothly.
  • Anti-rust: Thanks to the oil film, metal parts in the engine are protected from contact with air, thereby minimizing the risk of oxidation and rust.

Consequences of using poor quality oil

Using poor quality oil can have serious consequences for the engine:

  • Increased fuel consumption: Poor quality oil can increase fuel consumption by up to 6%, directly affecting vehicle operating costs.
  • Reduced engine life: Studies show that using poor quality oil can reduce engine life by 30% to 40%, equivalent to about 2-3 years of use.
  • Serious damage: The accumulation of dirt due to poor quality oil can lead to damage to internal engine parts such as pistons and cylinders, causing repair costs of up to tens of millions of VND.

Lubricant classification

There are three main types of oils commonly used in car engines:

  • Mineral oil: Cheapest but also lowest quality. Not recommended for modern cars.
  • Semi-synthetic oil: A combination of synthetic oil and mineral oil, providing better performance than mineral oil.
  • Synthetic oil: Although more expensive, it provides the best performance for the engine. It can operate in a wide range of temperatures without denaturing.

How to choose the right lubricant

To choose the right oil for your vehicle:

  • Consider environmental conditions: You should choose an oil with a viscosity index suitable for weather conditions in Vietnam (for example: 5W-30 for summer).
  • Follow manufacturer's recommendations: Read the manufacturer's recommended specifications carefully to choose the most suitable oil for your vehicle.
  • Regular Oil Changes: Make sure to change your oil on a regular schedule to maintain optimal engine performance.

Choosing and using the right type of lubricant not only affects the performance of your vehicle but also determines the life of the engine. Invest in quality products to ensure your vehicle is always in the best condition.

FAQ – Frequently Asked Questions

1. How to determine the quality of lubricating oil?

The quality of a lubricating oil can be determined by the ratio of base oil to additives. High quality oils usually contain at least 20% additives, while poor quality oils can contain up to 75-95% base oil.

2. Why should you use synthetic oil instead of mineral oil?

Synthetic oils are able to operate in extreme temperatures, which improves engine performance and reduces wear. They also have better detergent properties, helping to clean away dirt more effectively than mineral oils.

3. How does oil viscosity affect engine performance?

Viscosity directly affects lubrication and fuel consumption. Oil with too high viscosity can increase fuel consumption by up to 6%, while viscosity that is too low can lead to rapid wear of internal components.

4. What types of oil are suitable for cars?

Common types of lubricants include:

  • Mineral oil: Cheap but poor quality, not recommended for modern cars.
  • Semi-synthetic oil: A combination of mineral and synthetic, providing better performance.
  • Synthetic oil: Most expensive but provides optimal performance and the best engine protection.

5. What are the signs that indicate an immediate oil change?

Signs that your oil needs to be changed include:

  • Oil warning light is on.
  • The viscosity level drops rapidly.
  • Strange noise from engine.
  • Reduced performance or increased fuel consumption.

Understanding this information will help car users make better decisions in maintaining and servicing their vehicles, thereby extending engine life and saving repair costs.
