Importance of Fuel Tank Capacity


The fuel tank capacity of a vehicle is an important consideration for drivers, as it determines the maximum range and the frequency of refueling stops. A larger fuel tank, like the 18.5 gallons in the 2014 Subaru Outback, can provide more flexibility and convenience for long-distance driving or off-road adventures. This can be especially useful for those who live in rural areas or frequently travel on highways with fewer gas stations.


In summary, the 2014 Subaru Outback has a fuel tank capacity of 18.5 gallons, which is a standard size for a midsize crossover SUV. This tank size, combined with the vehicle's fuel efficiency, can provide a good driving range and minimize the need for frequent refueling stops.
