What are you paying (total) per gal for your WVO?
Curious what the average costs are, optionally post where you are and other details. Whether the WVO is used straight or turned into biodiesel is beside the point, i'm just talking about getting the WVO itself.
By total I mean if there are ancillary costs (driving 60 miles to pick it up, the cost of replacement filters, or whatever) you try to include that too. Getting veggie oil for free after a 120 mile trip with a pickup getting 12mpg isn't really free.
