The Vital Role of Oil Filters in Protecting Your Vehicle’s Engine

Mr. Ba, the meticulous owner of a small grocery store in Hanoi’s Old Quarter, has relied on his 1-ton Hyundai Porter truck for over a decade. From navigating narrow city streets to traversing long country roads, his truck has been a steadfast companion.

Despite its age, Mr. Ba’s truck runs smoothly and rarely breaks down. His secret? “Meticulous maintenance, regular oil changes, and never underestimating the importance of the oil filter,” he shares. But what makes the structure of an oil filter so crucial? Let’s delve in with Hanoi Truck!

The Mighty Oil Filter: Small but Powerful

Though small, the oil filter plays a vital role in ensuring smooth and long-lasting engine performance. It consists of three main components:

1. The Filter Housing

• Material: Typically made of high-pressure resistant metal or hard plastic.
• Function: Protects the internal components of the oil filter and connects to the engine’s oil compartment.

2. The Anti-Drainback Valve

• Location: Situated at the oil filter’s inlet.
• Function: Ensures a one-way oil flow from the oil compartment into the filter, preventing oil backflow when the engine is off.

3. The Filter Element

• Material: Pleated filter paper capable of withstanding high temperatures and pressure.
• Function: Removes dirt, debris, and contaminants from the engine oil, ensuring clean lubrication for engine components.
