“Water flows, stone erodes; cars run, engines wear,” as the old saying goes! To keep your “steel horse” running smoothly on all roads, regular maintenance is crucial. Besides oil changes and tire checks, replacing the fuel filter also requires special attention. So, when is the right time to replace your car’s fuel filter? Let’s find out with XE TẢI HÀ NỘI in this article!

1. The Crucial Role of the Fuel Filter

Before delving into the specifics of fuel filter replacement intervals, let’s understand the vital role of this small component.

Mr. Nguyen Van A, an automotive technical expert at THACO Trường Hải truck manufacturer, shares: “The fuel filter acts as the “lungs” of the engine, removing dirt and impurities from the fuel, ensuring that the gasoline supplied to the engine is always clean, contributing to stable and durable vehicle operation.”

If the fuel filter becomes clogged, the fuel supply to the engine will be reduced, leading to sluggish performance, difficulty starting, and even stalling.

2. When Should You Replace Your Car’s Fuel Filter?

According to expert recommendations, you should replace your fuel filter every 20,000 – 40,000 km or every 2 years, depending on operating conditions and fuel quality.

Additionally, you should also consider replacing the fuel filter when your car exhibits the following signs:

Difficulty Starting: A clogged fuel filter hinders fuel from reaching the engine, causing difficulty starting, especially in the morning.
Sluggish Acceleration and Jerking: Insufficient fuel supply causes the car to lose power and accelerate poorly.
Increased Fuel Consumption: A dirty fuel filter forces the engine to work harder to generate the same power, leading to higher fuel consumption.
Illuminated Check Engine Light: This is a general indication that there’s a problem with your vehicle.
