Replacing your Fuel Filter. When is the right time?

What are the benefits of changing my fuel filter?

A fuel filter is one of the most overlooked filters on your car usually because the filter can often be under the car, in the fuel tank or a tight inaccessible spot in the engine bay. But changing the fuel filter in your car at the regular service intervals can help in keeping your car running smooth, fuel efficient and healthy for the life of the vehicle.

As a rule of thumb Most fuel filters should be replaced every 30,000 to 40,000 kilometres as per your scheduled servicing, however, if you drive down dusty roads, fill up at small country service stations regularly or use your vehicle for a little bit of 4x4 adventure than you should have your fuel filter replaced at least every 20,000km. Keeping your fuel system clean not only protects the life of the engine, but actually saves you money in fuel.

Cracks and wear are very common on fuel hose due to the properties of the fuel drying out the lines and chewing away at the rubber.
