We are decommisioning a large piece of electrical equipment soon. I will have free access to about 250 gallons of transformer oil.

Diala Oil AX inhibited electrical insulating oil

"contains highly refined petroleum oils"

So I know it isn't the peanut oil variety. It is also not the old toxic oil because this piece of equipment was put into service new in 2007.

I know I can burn it in my 7.3 diluted with diesel. I figure at a 50/50 mix I can cut my fuel cost in half for the most of the summer.

Who here is doing this already and would like to share some insight? I am really looking for real world experience as this will be my first major venture into alternative fuel.
