WHAT IS ENGINE OIL? CLASSIFICATION AND HOW IT WORKS IN A CAR

I. WHAT IS ENGINE OIL?

Engine oil is a specialized lubricant used in automobile engines.

Unlike regular oil, engine oil is designed to:

- Withstands high temperatures

- Withstands high pressure

- Operates continuously in harsh environments

Oil not only helps the engine run smoothly but also plays a crucial role in protecting the entire machine system.

II. WHAT IS THE PURPOSE OF ENGINE OIL?

DThe engine head performs multiple functions simultaneously:

- Lubricate metal parts

- Reduces friction and wear.

- Engine cooling

- Clean off dirt and grime.

- Antioxidant protection

If there is a lack of oil or the oil is degraded, the engine can quickly become damaged.

III. HOW DOES ENGINE OIL WORK?

When the engine is running:

- The oil pump will draw oil from the crankcase.

- Push the oil through the oil lines

- Apply to the surface of the piston, crankshaft, and camshaft.

Here, the oil forms a thin film that helps:

- Reduce direct friction

- Reduces wear and tear

- Maintain a stable temperature

The oil then returns to the crankcase and the cycle continues.

This process occurs continuously while the vehicle is in operation.

IV. CLASSIFICATION OF COMMON ENGINE OILS

1. Mineral Oil

- Cheap

- Suitable for older cars

- Short lifespan

2. Semi-Synthetic Oil

- Better performance than mineral oil.

- Reasonable price

- Suitable for common vehicles

3. Fully Synthetic Oil

- High heat resistance

- Good viscosity stability

- Optimal engine protection

This is the recommended type of oil for modern vehicles.

V. MEANING OF OIL VALUE INDICATORS (5W30, 0W20…)

Example: 530

- The number before the "W" indicates the ability to operate in cold conditions.

- The last number: viscosity when the engine is hot.

Oil with the appropriate viscosity index will help:

- Easy startup

- Provides good protection at high temperatures.

VI. HOW TO CHOOSE ENGINE OIL?

When choosing oil, consider the following:

- Recommendation from the car manufacturer

- Operating conditions (urban, long-distance)

- Engine type

In the context of Vietnam:

- High temperature

- Frequent traffic jams

- Oils with good thermal stability should be preferred.

VII. HOW OFTEN SHOULD ENGINE OIL BE CHANGED?

Common recommendations:

5.000 – 10.000 km

If the vehicle is driven under the following conditions:

- Many in the inner city

- Traffic jam

- Heavy load

- It should be replaced sooner.

VIII. CONCLUSION

Engine oil is not just a lubricant; it's also a crucial factor in determining engine lifespan.

Understanding correctly:

- How it works

- Classification

- When to change the oil

This will help you:

- Better protection for the vehicle

- Reduce repair costs

- Increases engine durability
