How Often Should You Replace Your Fuel Filter

How Often Should You Replace Your Fuel Filter

Fuel filters are one of those things that we all know must be important but somehow most of us don’t know all that much about them. What are they? What do they do? WHY are they important? And how often should we be replacing them? Here’s all you need to know.

Every car is equipped with a fuel filter as they are critical in keeping the fuel delivery system in working order. Their job is to prevent dirt and debris from entering the fuel system. Without them, the fuel system will become compromised with contamination of dirt, rust and/or debris. In short - without them the engine will go bust. 

However, these filters are not made to last forever. They, of course, will clog up over time and if they are not replaced, will cause the fuel pump to work harder and harder. This can result in serious damage to the fuel pump. So, the question is “How often does the fuel filter need to be replaced?”

The rule of thumb is that most fuel filters should be replaced between every 30,000 - 40,000 Kms as per scheduled servicing. However, if you often drive down dusty roads, regularly fuel up at small country town fuel stations or take your vehicle for a bit of offroad 4x4 adventuring, then you should replace your fuel filter at least every 20,000 Kms. This will ensure your engine is kept clean, its life is prolonged and that you save yourself from far more expensive problems down the road.
