I am retired from petroleum logistics management. I oversaw the fuel receipts from oil tankers, rail, tank trucks, or pipeline and transferred it to the end customer...typically an aircraft or vehicle. There was all sorts of equipment and people involved in the process as well as storage, purity testing and accounting. I dealt with gasoline and diesel a little, but mostly jet propellants (JP-4, JP-8, JPTS and some cryogenics LOX/LIN). I hated it, but was addicted to regular paychecks...
