Synchromax is recommended for manual transmissions that require either automatic transmission fluids, multi-viscosity motor oils or straight grade motor oils. It is also ideal for 2-cycle motorcycle gear boxes. It offers improved shift quality over a wide temperature range and reduced gear noise. Synchromax reduces friction for more power, provides superior corrosion protection and lowers operating temperatures. Its superb oxidation stability extends oil life and cleans gear boxes.
