Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 517 gallons, roughly 42 full tanks.
Fuel gauges aren't perfectly linear and the low-fuel light comes on with a few gallons still in the tank, so plan your stop before the last eighth.
At 12.4 gallons, the Focus's largest tank ranks sixth of the seven 2017 sedans compared here. The Subaru WRX carries the most (15.9 gal) and the Honda Civic the least (12.4 gal).
