Not an exact answer, but a good explanation of the process involved.

Crude Oil
It takes about 2.14 gallons of crude oil to make one gallon of gasoline.
It takes about 2.14 gallons of crude oil to produce one gallon of gasoline.
It takes about 2.1 gallons of crude oil to produce one gallon of gasoline.
It takes about 2.14 gallons of crude to get a gallon of gasoline. so 9 gallons would take 19.26 gallons of crude. 9*2.14=19.26
Gasoline is refined from oil in a matter of hours. Refineries that make oil, diesel, gasoline, naphtha and other products out of crude oil process 100,000 barrels or more of crude oil per day.
Gasoline and kerosene are both derived from crude oil but have different boiling points due to their molecular composition. Gasoline has a lower boiling point and evaporates faster than kerosene. There isn't a specific time frame for gasoline to turn into kerosene as they are distinct products with different properties.
This question can be answered in three ways. It takes 1851 gallons of water to refine a barrel of crude oil. One barrel of crude oil produces 19 gallons of gasoline and 10 gallons of diesel fuel, in this respect it takes 97 gallons of water to produce a gallon of gasoline. If you combine gasoline and diesel, it takes 63 gallons of water to produce a gallon of "fuel." A total of 42 gallons of petroleum products are produced from a barrel of crude oil, in this respect it takes 44 gallons of water to produce each gallon.

Crude oil is regular oil. It is the raw oil extracted from the earth. It is referred to as crude as it must be refined so its components can be used.
