Yes, a clogged fuel filter can lead to poor fuel economy in your Suzuki Alto. The fuel filter’s job is to trap impurities in the fuel before it enters the engine. Over time, as the filter becomes clogged, the engine may not receive the proper amount of fuel, causing it to work harder to operate, which can reduce fuel efficiency.

Signs of a Clogged Fuel Filter:

Decreased Fuel Economy: You may notice that your fuel tank empties quicker than usual.
Engine Hesitation o r Stalling: The engine may hesitate o r stall when accelerating, especially when trying to drive at higher speeds.
Difficulty Starting: A clogged fuel filter can make it harder to start the engine, particularly after the car has been idle for a while.
Solution:

Check the Fuel Filter: If you notice poor fuel economy o r performance issues, inspect the fuel filter for dirt o r clogging.
Replace the Fuel Filter: The fuel filter in most cars should be replaced every 30,000 to 40,000 kilometers, but this can vary based on driving conditions. If you frequently drive in dusty areas, you may need to replace it more often.
Regular Maintenance: Have the fuel filter checked during routine maintenance, especially if you’re noticing performance issues.
