weasel:
Not the same idea, but I have a friend who mixes used motor oil 50/50 with diesel and seems to do well, in the winter he runs 30/70. Where I work we have to pay someone to haul off our used oil.

efremtags:
I do not make fuel first hand but have done some research when fuel was 4.50/gal.

Northern tool sells the fuelmeister II which is a semi-automated machine that will make 50 gal at a a clip in a day.

The complications are you need a free source of waste oil (local restaurtants), but more importantly the means to get the fuel which means pumps, storage, filtration and a means of disposeing the glycerine by-products. This is not trivial as if you make a hundred gallons a month of fuel, you will quickly accumulate a lot of waste.

The process is pretty easy, a simple test of PH and oil composition, add some lyme, heat, agitate, and in 12 hours you have fuel.

You can build your own machine, but it's pretty time consuming and requires a lot of hands on to maintain the process control.

good stuff, but don't let it get cold.
 pure Bio will gel at around 45'.
we ran it for a couple of years in our fleet and even at a B-10 concentration (10% bio), we'd be replaceing filters when it got below 40'
something to consider

Same thing happened here, it started clogging filters when the weather turned cold. Also do not advertise that you are using nontaxed fuel in your vehicle, we had one gentleman here that MNDOT pretty much bankrupted with fines and penalties. I had warned him not to brag with signs on his vehicle, but he did not head and was nailed to the wall.

As an old Indian once told me "never steal from the government, they hate competition" ya know what, he has never been wrong on that account.
