A 50,000 interval service is required for both the filter and the double clutch transmission fluid. The Pentosin FFL-3 is founded on a fully synthetic base oil technology for safe operation at even the highest thermal load. FFL-3 features a special clutch friction performance which makes it mandatory to be applied solely to the double clutch gear box, do not mix with any other gear oils.
