Over 15,000 miles a year (the EPA's yearly estimate) this configuration uses about 600 gallons, roughly 38 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 15.8 gallons, the Cherokee's largest tank ranks second of the seven 2018 SUVs compared here. The Toyota RAV4 carries the most (15.9 gal) and the Nissan Rogue the least (14.5 gal).
