High pressure viscosity characterization of four vegetable and mineral hydraulic oils

In the long term, environmental friendly oils from renewable sources seem to be the more realistic path to a sustainable future for the industry regarding the lubrication issue. Vegetable bases for lubricants have been studied in the last decade in order to analyze their potential industrial applica...
