Biodegradable Synthetic Hydraulic Oil is compatible with most synthetic and petroleum-based hydraulic oils. Mixing AMSOIL oils with other oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. To ensure proper performance, it is recommended systems be drained and flushed prior to installation.
