Does anyone know if this product was the real deal. The product isn't made anymore. It was made by a company named Kemco. It was the only product that still contained real tetryl ethyl lead additive and it not only lubricated the valve seats but increased octane levels. Does real tetryl ethyl lead really do that and is there an alternative to the defunct Supreme Octane 130?
