3 grand??==PPHHHT!!
For 3000 dollars,I could buy enough diesel fuel to drive my truck 10 years or more..I dont drive much more than 5000 miles a year!--and I have other vehicles to drive too,so not all those miles would be in the diesel truck..
I asked several fast food joints here if they would give me their used oil--all of them are required by law to keep records of how much oil they buy,and who takes it away(all have subcontractors taking it away,and they sell it to Bio-Diesel companies)..they have to prove how they disposed of it--even "Ma and Pa" type food places are not exempt--if they use oil,it must be accounted for...this may not be true everywhere,but it is in my area..and thats all I care about!..bottom line?--if you want free oil,you wont get it here!--a few places DO give it away,but technically its illegal to do so,and they have more guys wanting it than they have to dispose of..
This does not take into consideration the effects burning something the engine was not designed for will do to it!..it might clog injectors,harm the injection pump,etc.I can picture the sludge building up in the rings and crancase!

--.Plus it can't be used in cold weather..I dont really see the big advantage to using waste vegatable oil..maybe in an 18 wheeler,that consumes much more than a pickup...I think its a waste of time to pursue it for the "average Joe"...too complicated and difficult..
If you live in Texas,or Pennsylvania,you'd be better off drilling your own well..

I think its a disservice to make people think its a viable alternative,when you cant even GET the used oil to begin with,in many cases..
BUT--I wonder how much "Canola" oil or "Peanut Oil" costs per gallon??...if its less than 3 bucks,It might be worth buying!..

--and if Olive oil burns like diesel,you could always plant an olive tree!...I'd go for Hemp Oil myself...
