This is interesting and valuable!
It just recently dawned on me that bio-diesel has been around.. Reason being, I am getting near the finishing point in my swap to diesel with my truck (5.8 gas to 7.3 DI).. i have never owned a diesel before, so I never gave this much thought..
Then today, a family member of mine who is the store manager at a fast food place was talking to me about the fact they have so much used oil from their cookers, and disposing of it is a pain...
Duh! It hit me... "Wait a minute.. I now own a diesel, and could use this stuff"! Needless to say.. I now have access to a few fast food joints and their used oil.. I like the idea of recycling this stuff, and not paying $4 a gallon!
Now I found this thread, and seeing you guys put together your own processing plants, and sharing info and tips, Hmmm.. This is very tempting to get started!
I already called around on some drums to start storing the stuff, as there is sooo much to learn!
