Microlon has been in business since 1964 and we have seen dozens of similar products come and go. Most of the other products are oils or oil treatments while Microlon is a one-time metal treatment. Microlon can be used to treat the top end of the engine through the fuel and the rest of the engine through the crankcase. Microlon CL-100 has been accepted for use in aircraft engines up to 1000 C.I.D. since May 1979. Microlon was entered into an invention competition and won the gold Medaille de Vermeille in Geneva in 1978. No one has been able to duplicate the formulation or its effects since it was invented in 1964.
