PolyDyn TX7 is a revolutionary Engine Treatment. It coats vital engine parts reducing friction and heat. An application of PolyDyn TX7 Engine Treatment can add years to the life of your engine, increase its efficiency, and reduce maintenance costs. The drastic reduction of friction and drag inside the engine allows it to develop more power with the same amount of fuel, thus increasing RPMs and fuel efficiency. How does TX7 accomplish this? By burnishing TFE particles into the irregularities of the metal surfaces – where you once had metal to metal, you now have TFE to TFE. This reduces metal interface friction, heat build-up and increases efficiency.
