Attention: TDR Forum Junkies With prices going up on fuel, I was wondering if hydraulic oil can be "refined" in a cost effective manner. I figure WVO is going to become a commodity if it is not already. My company goes through about 1k gallons a week, which they pay to have hauled away. I ask because many hydraulic oils(unless synthetic) are veggie based. Anybody in the area that is making biodiesel and wants $100. 00 to try the process with hydraulic P. M. me.
