Fuel filter Smart

Every Smart is equipped with a fuel filter. Your Smart fuel filter needs replacing every 12 400 to 24 800 miles.

The fuel filter makes sure the fuel that gets injected into the engine of your car is clean and does not contain any particulates which can cause premature wear or even damage your car's engine. Any particulate, however small, can easily damage the engine cylinders or the fuel injectors.

Especially as fuel filters are not exactly the most expensive of car parts, there is no need to delay this upkeep of your car.
