Any of the WEO's will run at 10% - no problem. Used engine oil, used trans oil, used power steering oil, tractor hyd oil, and transformer oil - I have run all of these at around 20% in the boss's truck, he provided the barrels and pump.
The additive package for some of the oils has changed since so the 10% recommend as a limit unless you do your own fuel system work.
For HP gear lube if it needs to go with the mix I would cut it 10:1 into a lighter oil before mixing with #2.
Same on veggie oil but much more care in filtering and check for sodium content. New is no sodium content but used may be corrosive with salt.
Likewise I would avoid red dye in the oil because of the tax consequences.
