All ZF transmissions are therefore filled with the semi-synthetic or fully synthetic premium grade oil ZF-LifeguardFluid. Thanks to the optimization of the lubrication properties, a lower fuel consumption and, consequently fewer CO2 emissions, is achieved. Under normal conditions, it lasts a vehicle's entire life cycle, but it can age prematurely in case of excessive loads – such as from frequent use of trailers or quick, sporty driving. Therefor an oil change is recommendable after 80 000 to 120 000 kilometers or eight years.
