鷹潭市余江區美孚Mobil液壓油-導軌油經銷良好的抗氧，防老化性能，可延長換油周期。TOST壽命試驗結果超過2000小時。
優良的防"爬行"性能，在液壓缸使用的密封材料時，如果機器處于低負載和慢運行狀態，容易造成"爬行"現象。的得力士液壓油能極有效地克服這各現象的發生，從而使柱塞動作更加平穩流暢。
良好的空氣釋放性能，避免產生氣穴和氣蝕。
良好的分水性能，在許多液壓裝置中，由于溫度低，水份無法得到充分的揮發，所以油的分水性能便顯得很重要。在ASTM D1401試驗中，得力士能在很短時間內與不完全分離。Good antioxidant, anti-aging performance, can extend the oil change cycle. Tost life test results exceed 2000 hours. Excellent anti-“Crawling” performance, in the hydraulic cylinder using advanced sealing materials, if the machine in low load and slow running state, easy to cause“Crawling” phenomenon. The advanced delis hydraulic oil can effectively overcome this phenomenon, thus making the plunger action more smooth and smooth. Good air release performance to avoid cavitation and cavitation. Good water separation performance, in many hydraulic devices, because of the low temperature, water can not be fully volatile, so the water separation performance of oil is very important. In the ASTM D1401 trial, Tetris was able to separate from incomplete separation in a very short time.
