Running waste veggie oil without extensive cleanup will result in horrible "resinification" (varnish) all over everything. You must remove the protein, and preferably the phospholipids before use.

Also, veggie oil, untreated, is too viscous cold to get sucked up into the IP, so the engine will stop. Likely the filters will plug almost instantly, too, unless the oil is pre-treated.

Biodiesel is fine -- but it won't be $.46 a gallon, either.
