Water emulsion or water held in suspension can cause serious damage to fuel system components. The water content causes loss of lubrication resulting in worn fuel pumps and injectors.

Emulsified water also reacts with chemicals in the fuel at the point of combustion, which causes contaminates such as gum, wax and resin to separate and foul fuel systems, especially injectors. Emulsified water can seriously degrade certain types of fuel filters.

A water emulsion, left untreated eventually separates from the fuel and provides an environment for the 'diesel bug' .

Fuel Set chemically bonds emulsified or free water into the fuel. This eliminates the harmful effects of water in fuel systems. Having water as part of the fuels’ make-up lowers smoke and nitrous oxide emissions.
