How big is a tank on Ford Focus?

The fuel tank size in a Ford Focus varies depending on the model year and engine type. There's no single answer. To find the exact capacity for your specific Ford Focus, you should:

* Check your owner's manual: This is the most reliable source.

* Look inside the fuel filler door: The fuel tank capacity is sometimes printed there.

Expect the capacity to be somewhere in the range of 12 to 14 gallons (45 to 53 liters), but again, this is just an estimate.
