Fuel moisture displacers

To displace moisture from fuel

— additives positioned as compounds for removing (displacing) moisture from fuel. It is worth noting that this name is not entirely correct: in fact, we are not talking about the removal of water, but about its uniform dissolution in the fuel.

Despite the fact that a working fuel system is sealed, some water somehow gets into the fuel — for example, along with air entering the tank and when the cap is opened, and sometimes due to the low quality of gasoline itself. In this case, the main danger lies not in the presence of water itself, but in the fact that it can be concentrated in the lower part of the tank. The fact is that even in a rather poor-quality fuel there is relatively little water, and if it is evenly distributed throughout the volume of gasoline, this does not create any special problems. However, problems can arise with this distribution: water does not dissolve in gasoline and weighs more than it, so when it is parked for a long time, it settles in a separate layer at the bottom of the tank. And since the fuel intake is carried out just from below, then at the next start-up, the fuel system may not draw gasoline, but water.

To avoid these troubles, additives of this type are used. Their composition is selected in such a way that a mixture of water and such an additive dissolves in gasoline without restrictions. Thus, water does not settle at the bottom of the tank, but enters the engine in microscopic portions along with gasoline and “flies out into the pipe” in the form of steam.

The use of moisture-displacing nozzles is especially important during long-term parking in the cold season. Note that most of these compounds must be poured into an empty or almost empty tank before the next refueling.
