All Makes and all Models? A debate with no clear-cut answer

摘要

This year, Valvoline Co., maker of Zerex, took Honeywell, maker of Prestone, to task for its "all makes, all models" antifreeze advertising. Valvoline challenged Honeywell's advertising claims that its Prestone Extended Life Antifreeze/Coolant can be used in all makes and models of automobiles and light trucks before the National Advertising Division (NAD) of the Council of Better Business Bureaus. NAD also reviewed whether the antifreeze is compatible with all other antifreeze products.
