Torco MPZ magnetic friction reducer offers increased horsepower and torque proven over millions of racing miles since its development in 1973. It can also be used as an engine break-in additive for reducing friction and wearing in new and rebuilt engines. When added to motor oil, it reduces frictional heat on racing valve springs to prevent the loss of spring tension. Torco MPZ magnetic friction reducer increases fuel mileage by reducing friction on cylinders, rings, and valve train parts when added to motor oil. When engine parts reach their threshold, it protects with a boundary lubricating film, which provides an anti-wear separation layer between all metal engine components.
