Is there any way I can use the old peanut oil in the diesel or would this be more trouble than it's worth?

Benzdriver,

No problem if you heat the WVO enough to get any water out and filter the WVO good.

Mix in with dino Diesel and go.

We've always just filtered the peanut oil real good and stored it in sealed containers for the next turkey fry. :p

Oil containing meat particles will get ransid if not kept in the fridge.
