Can a Dirty Air Filter Lead to Poor Fuel Economy in Suzuki Cultus?

My Suzuki Cultus has been consuming more fuel recently, and I’m considering that the air filter might be clogged. Could a dirty air filter affect the engine’s performance and lead to poor fuel economy? How often should the air filter be changed o r cleaned to keep the fuel efficiency intact?

Yes, a clogged o r dirty air filter can reduce fuel efficiency in your Suzuki Cultus. The air filter’s role is to ensure that clean air is supplied to the engine for combustion. If the filter becomes clogged with dirt and debris, it restricts airflow, which can reduce engine performance and increase fuel consumption.

Symptoms of a Dirty Air Filter: If the air filter is dirty, you might experience poor acceleration, reduced engine power, o r increased exhaust emissions.
How It Affects Fuel Economy: Less air reaching the engine means the engine may burn more fuel to maintain the same power output, leading to inefficient fuel use.
Solution:

Check and Replace the Air Filter: The air filter should be inspected and replaced regularly. Depending on driving conditions, this could be every 12,000–15,000 kilometers. If you drive in dusty areas, you may need to replace it more often.
Cleaning: In some cases, air filters can be cleaned, but replacing them is usually the best option for optimal performance.
