Hi Adam >Hi Keith, >Which kind of WCO (rapeseed oil, lard, tallow, UCO) is the most cost >effective and efficient for making bio-diesel?
What's UCO? Used cooking oil? Different to WCO (WVO?)? Anyway, that's an impossible question to answer, users' circumstances and the availability and condition of oils varies too widely. use whatever you can get, as long as it's not a drying oil.
