A fully synthetic fluid engineered for non-synchronized manual transmissions to meet the extreme demands of road racing, oval track and drag racing. Driven MTF lowers operating temperatures, reduces parasitic drag and provides smooth shifting. Ideal for integrated transmission/spiral bevel rear gear boxes. It has a viscosity rating of 80W meaning that compared to a traditional 75W-90 it will reduce drag and temperature in racing gearboxes. Its unique additive package provides excellent anti-wear protection. The MTF should not be used in synchromesh gearboxes.
