Car filters are essential for the proper functioning of the vehicle. They prevent dirt, dust and impurities from reaching sensitive areas of the engine or the cabin. Replacing them on time improves performance and prevents breakdowns. At Alas Estaciones, we explain when to change your car’s filters and why it’s important.
Car filters, their function and how often to replace them
Each filter plays a key role in the protection and efficiency of the vehicle.
Air filter
It prevents dust or particles from entering the engine. A dirty filter forces the engine to work harder, increasing fuel consumption and reducing power.
It is usually replaced every 15,000 to 30,000 km, but if you drive in dusty areas or on unpaved roads, it’s best to change it sooner.
Oil filter
Its function is to prevent impurities from circulating with the engine oil. If it’s not in good condition, the engine may wear out prematurely.
It is typically replaced along with the oil every 10,000 to 15,000 km, or once a year. It is one of the most important filters for engine health.
Fuel filter
It traps particles that may be present in petrol or diesel. Poor filtration can affect the injectors and cause combustion issues.
In diesel engines, it is normally replaced between 30,000 and 60,000 km. In petrol engines, it may last a bit longer. Checking it helps prevent injector problems and starting difficulties.
Cabin filter
It purifies the air that passengers breathe, trapping dust, pollen and contaminants. It is essential for good ventilation and especially important for people with allergies.
It is recommended to replace it every 15,000 km or once a year. If you notice bad odours from the ventilation system or reduced airflow, it needs replacement.
Why is it important to replace them on time?
They protect the engine
Clean filters prevent wear, vibrations and combustion problems. A neglected filter can lead to serious issues.
They improve performance and reduce consumption
An engine that breathes and lubricates properly works more efficiently. Keeping the filters in good condition helps save fuel.
They prevent costly breakdowns
Injectors, fuel pumps and internal engine components can be damaged if impurities reach them. Replacing a filter is inexpensive; repairing a breakdown is not.
They take care of passengers’ health
The cabin filter improves indoor air quality, especially important for people with allergies or asthma.
Conclusion: simple maintenance with big benefits
Knowing when to change your car’s filters and why it’s important is one of the simplest and most economical maintenance tasks, but also one of the most essential. At Alas Estaciones, we help you keep them in good condition. Taking care of your car means taking care of every journey.
