Trucks that deal in petroleum services, such as Nelson Petroleum, often transport petroleum and natural gas back and forth over the ground. Ironically, these trucks run on the very gasoline produced from petroleum. Ergo, you have a giant tank of what will become gas on the back of a truck that runs on gas. Yet, what happens when this kind of truck runs out of gas? While it is unlikely that any driver of a petroleum service truck would allow that to happen, it is not impossible and it has happened. Still, the petroleum truck cannot refuel itself in this situation. Here are three reasons why.
One: The Truck Is Transporting Raw Petroleum
Raw petroleum needs to go through a refinery before it can be converted to gas and other petroleum-based products. Since most vehicles, including the petroleum truck, cannot operate on the thick, black oil harvested from the ground, the petroleum truck cannot refuel itself using the raw fuel it is carrying. The engine in the truck could not handle or process the fuel in the way that it should, and in diesel engine trucks, it definitely could not.
Two: It Is Theft
Even if you could use the raw petroleum to fuel a petroleum truck, it is considered theft. You would be stealing company property to fuel the vehicle. Despite the fact that the vehicle is (probably) company property as well does not make it any better. You could be fired or worse for stealing a company product to fuel the petroleum truck.
Three: There Is No Way to Dispense the Product into the Petroleum Truck's Gas Tank
Finally, for the sake of argument, let's say you could use the product the petroleum truck is hauling and you would not get into trouble for theft. You still have the problem of dispensing the product from the tanker to the truck's gas tank. There are no attachments on a petroleum truck that would allow you to dispense product into the gas tank of the truck.
There are no control valves for this either. Most of the control valves on a petroleum truck would release the product in a massive gush from either the rear of the tanker or from the top, depending on how the tanker is filled at the time the product is picked up. That said, you would need another truck, such as a tow truck, to bring actual gas to the petroleum truck so that it can deliver its full tank of petroleum to its destination.
