The list of solvents and their Solubility Parameter is provided to illustrate the difference in energy that solvents possess because of their different molecular structures. This parameter is measured in calories per centimeter (cal/cm.). The larger the value of Solubility Parameter, the greater energy the solvent has to dissolve gum, varnish and other fuel system and engine deposits.
You only have to compare labels to determine which fuel additive products contain H.E.S.T. The use of strong, high energy solvents, combined with state-of-the-art polymeric additive technology give Berryman Products a more complete combination of available chemical technologies. It provides the one, two, punch to knock out engine and fuel system deposits.
