It is important to keep the fuel filter clean

What is the news?

It is very important for the fuel filter to be in good condition for good performance and long life of the car or bike. This small, but important part prevents dust, dirt, and impurities in the fuel from reaching the engine. If it is not cleaned or replaced on time, the vehicle’s power, mileage and engine health can be directly affected. Ignoring this can lead to big and expensive problems in the future.

When should the fuel filter be changed?

It is generally recommended to change the fuel filter every 20,000 to 40,000 kilometers, but this interval also depends on the model and usage of the vehicle. If the vehicle is taking time to start, is jerking frequently, or has poor pickup, it may be a sign that the filter needs to be replaced. Changing fuel filter timely keeps the engine safe and strong.

What harm does a dirty filter cause?

If the fuel filter becomes dirty or clogged, the fuel cannot reach the engine properly. Due to this, the engine does not get sufficient and clean fuel and it runs intermittently or unevenly. If this happens for a long time, extra pressure on the engine increases and many important parts inside can get damaged quickly. Due to this, mileage reduces, smoke may increase and the power of the vehicle also gradually starts decreasing.

It is wise to change on time

Changing the fuel filter is not a very expensive or complicated task, but putting it off can cause serious damage. During regular service, get it checked by a mechanic and if necessary, get it replaced immediately. By providing clean and pure fuel, the life of the engine increases and the vehicle runs smoother and better. If you want better mileage, lower expenses and safe driving, then changing the fuel filter on time is the easiest and most reliable solution.
