It varies by density and temperature, so I chose Kerosene.

5,875,000 TONS more or less. I wouldn't be all that surprised that with all the mixes and grades of fuel if it were six to six and a half million tons or more.

6,412,005 metric tons based on a specific gravity value of 8.60 for the oil.

Determining oil tonnage used depends on if you are specifying refined or crude?
If it is crude, then you still have problems. Pennsylvania crude, Texas crude and Saudi crude don't weigh the same by the barrel.
When you go into the millions of barrels those kilograms of difference per barrel per source pumped just add up.
