The fuel filter of your car ensures that your fuel is cleaned of dirt particules before it is injected into the engine. This is important for the lifetime of the engine.
At Mister-Auto.co.uk we therefore recommend you always buy fuel filters from quality brands.
Although your garage will most likely replace your fuel filter along with the air and oil filters during servicing. Nevertheless you should ensure your fuel filter is changed every 12 400 miles for gasoline engines and every 24 800 miles for dieseloil engines.
The regular replacing of a fuel filter is especially important for a diesel engine as these tend to be more sensitive to irregularities in the fuel than gasoline engines.
