The tanks are sized accordingly. For example:
"Two 20,000 gallon tanks (40,000 gallons total), each with two compartments, creating storage capacities of 15,000, 5,000, 12,000, and 8,000 gallons
Two 12,000 gallon tanks and one 20,000 gallon tank (44,000 gallons total)
A 20,000 gallon UST for regular gasoline, a 12,000 gallon for premium, and a 6,000 gallon for diesel (38,000 gallons)
Two 30,000 gallon compartmentalized tanks (60,000 gallons total)
Some petroleum marketers anticipate fluctuating fuel prices and install more capacity so they can buy and store additional fuel when it is offered at lower prices—for example, two 20,000 gallon tanks, one 15,000 gallon tank, and one 12,000 gallon tank (67,000 gallons total)
One 25,000 gallon tank and one 22,000 gallon tank, split into two compartments (47,000 gallons total)
Stores that dispense biofuels separately may install total tank capacities as great as 60,000 gallons. At a truck stop, diesel tank storage can be another 30,000 gallons or more.
Small mom-and-pop stores install less capacity, perhaps two 12,000 gallon tanks (24,000 gallons total)
In extremely rural areas, a single 20,000 gallon tank with multi-compartments might be installed."
