If you're speaking of 'new' vegetable oil---like what you get from a grocery store or even a wholesale place like Costco, I would say 'no'.....Paid about $7.00 for 1/2 gallon of canola (I'm sure some places are a little cheaper), so do the math. Peanut oil is even more expensive.

I know most of the bio guys here score used oil from restaurants and such, so they pay little if anything for theirs. But they still need the equipment and the chemicals for the process.

Hey, TexHillCtry....What's it come out to per gallon now if you do it that way? Something just under $1.00/gallon or something?
