How long does the TX7 treatment last?
The initial treatment of TX7 in the average engine is good for approximately 20,000 miles. Since TFE is chemically inert, most solvents and detergents will not effect the treatment. Only excessive and constant rubbing may cause some TFE erosion to occur. By treating at intervals of 12,000 miles or once annually, the maximum benefits can be maintained indefinitely.
