Classic-car owners sometimes ask if they need to add a lead substitute to their gasoline. For decades, Tetraethyllead was added to gasoline to reduce engine knock and help prevent valve-seat recession. Once lead’s negative effects became clear, regulators began phasing it out in the 1970s. But, what about classic-car engines from the 1950s and 1960s that were built with leaded gasoline in mind? AMSOIL DOMINATOR®Octane Boostworks great as a lead substitute in classic cars.
