The Pentosin Fully Synthetic Double Clutch (DSG) Transmission Fluid is the only approved first fill and service fill transmission fluid for the new generation of AVW double clutch gear transmissions (DSG). The Pentosin transmission fluid is founded on a fully synthetic base oil technology for safe operation at even the highest thermal load. It features a special clutch friction performance which makes it mandatory to be applied solely to the double clutch gear box. NOTE: Do not mix with any other gear oils.
