How does traffic congestion affect transmission and engine oil?

No traffic jam.Not only does it waste fuel, but it also forces the transmission fluid and engine oil to work under much harsher conditions than many people realize. Prolonged high temperatures cause the oil to degrade quickly and affect the lifespan of the vehicle.

Traffic congestion is a much harsher operating environment than many people realize.

Many people believe that:

Driving on the highway is when the car does its hardest work.

But in reality, for transmission fluid and engine oil, prolonged urban traffic congestion is one of the most demanding operating conditions.

In large cities like Ho Chi Minh City or Hanoi, vehicles frequently have to:

- Stop & Go

- Running at low speed for extended periods

- Accelerate and brake repeatedly

- Operates in high-temperature environments

This causes heat to build up much faster than driving at a steady speed on the highway.

How much pressure does transmission fluid withstand when stuck in traffic?

In automatic transmissions, ATF oil has more than just a lubricating function.

It also performs the following functions:

- Hydraulic pressure transmission

- Cooling the internal components

- Controls gear shifting operation

- Protects the clutch and valve body

When the vehicle is constantly:

- Moving forward meter by meter

- Stop and then speed up

- Continuous load switching

- The transmission must operate continuously even when the vehicle has barely moved a short distance.

- The ATF oil temperature therefore increases much faster than many people think.

When temperatures rise for an extended period:

- Oil viscosity changes

- Reduced protection

- Clutch wears out faster

- The hydraulic pressure is less stable.

This is one of the common causes of this phenomenon:

- Winning the lottery

- Slow gear shifting

- Sliding gear

- Gearbox overheating

Engine oil is also affected to a significant degree.

Many people think:

- When the car is stationary, the engine doesn't have to work much.

The reality is quite the opposite.

When there's a traffic jam:

- The engine is still running continuously.

- The cooling fan is working harder.

- Engine compartment temperature rises

- Reduced heat dissipation due to lack of natural airflow.

This forces the engine oil to work under prolonged high-temperature conditions.

- If the oil is not of sufficient quality or is due for a change:

- The oxidation process occurs faster.

- Reduced lubrication

- More dirt and grime accumulate.

- Increased engine wear

SUVs, MPVs, and service vehicles are generally more affected.

In Vietnam, the following car models:

- SUV

- MPV

- Service vehicle

- Family car, frequently driven in the city.

These are the objects subjected to greater thermal stress.

The reason is:

- The vehicle is heavy.

- High load capacity

- High operating frequency

When combined with frequent traffic jams, the temperature of the transmission fluid and engine oil can rise significantly faster.

What happens when oil is regularly operated at high temperatures?

Temperature is the common enemy of both transmission fluid and engine oil.

When temperatures exceed optimal levels for extended periods:

- Oil degrades faster

- The additive protects against faster degradation.

- Reduced lubrication

- Shorter oil lifespan

In the long term, this directly affects:

- Transmission

- Engine

- Maintenance costs

- Repair costs

Conclude

Traffic congestion is not simply about cars moving slowly.

This is one of the most demanding operating environments for:

- Gear oil

- Engine oil

- Cooling system

Using the correct type of oil and performing regular maintenance are crucial for protecting your vehicle in the real-world traffic conditions of Vietnam.
