Q:

What happens when a gallon of sugar water is added to a car's gas tank?

A:

If one gallon of sugar water is added to a car's gas tank, it is likely that the car's fuel lines will get filled with water, potentially causing serious mechanical issues for the car. However, this is because gasoline floats on top of water, which means that water would be the first liquid available to the car's fuel pump, and not because of any potential harm sugar can do to a car's engine. In fact, the myth that sugar will immediately and permanently damage a car's engine has been proven to be untrue multiple times, although in theory, enough granulated sugar can clog a car's fuel filter as sand might.

Sugar doesn't dissolve in gasoline, meaning that adding it directly to the gas tank won't result in some sort of sugary gasoline solution as is purported by a popular myth. In the case of sugar water because it is more dense than pure water, it would sink below the less-dense liquid gasoline just as pure water would, meaning those who want to disable a car would do just as well adding pure water and leaving the dissolved sugar out of the equation. Sugar's potential harm for car engines is related to it its physical graininess.

    What could happen if someone puts sugar in a gas tank?

    A:

    Putting sugar in a gas tank may clog up a car's fuel filter, which could make changing the filter more frequently necessary, but it's unlikely to enter a car's fuel line and cause any serious problems. There are no particular chemical properties of sugar that make it react negatively with gasoline, and any problems caused by pouring sugar in a gas tank come merely from its granular qualities.

    What happens when you put sand in a gas tank?

    A:

    According to HowStuffWorks, pouring sand into a gas tank has the potential to clog up the fuel filter in a car, which causes the car to become disabled. However, the amount of sand that needs to be put into the gas tank to achieve this is great, and it is not guaranteed to work.

    What happens when syrup is put in a gas tank?

    A:

    The effects of putting syrup in the gas tank of a car depend on how far the syrup gets into the fuel system. If the car is started and run for any length of time, the syrup can end up clogging the fuel filter, which can cause the flow of fuel to be restricted, and in turn can cause the engine to stop running. If the syrup gets to the filter, the gas tank may need to be replaced.
