Im really not sure what the additives are that go into it. From what I understand you have a basic gasoline product and each company adds there own chemicals into it. It used to be years ago the guys would draw 10 or 15 gallons out of there barges for there vehicles (Yes this is stealing, and No I didnt participate) by the time I started this job the oil companies had cracked down on this. Naptha is one of the ingredients, which is basically lighter fluid. We also carry this stuff. Imagine 150,000 bbls of Lighter Fluid. That's why you really need to know your job and be very careful handling this stuff. Doesn't matter if it's tug and barge, platform, refinery, or whatever. As much of this stuff is moved in a day says something about the professionalism of the guys that do this kind of work.
