You asked, so here it is, and it's long.

I get asked this question all the time, so here is a cut and paste from another response I made. It may have more info than you want, but if it doesn't answer your questions just let me know and I'll be happy to elaborate.

I got started with the DSE stuff. I then did a lot more research. I continue to use the basic process, but I no longer use their additive and I have added some steps.

I have not heard first hand of anyone having any problem with the process beyond clogged filters. I have yet to clog a filter in my truck. I have only clogged the filter in the Mercedes that came with the car when I bought it, since then the junk has been cleaned out of the tank just through use and no problems since. In the begining I went through filters on my fuel processing station pretty regularly, but since changing up my process a little, my filters last hundreds of gallons. I probably have 600 gallons on the present ones now.

Here's what I do: I collect my oil by either picking up the cubies the restaurant has set out for me or by using a pump to pull the oil out of a dumpster and put it into 5 gallon buckets. My first 55 gallon drum has a hole cut in it the allows a 5 gallon bucket to be inserted like a cork in a bottle. This 5 gallon bucket has a bunch of holes drilled in the bottom. I line this bucket with a pillow case (I buy them at the thrift shop for 50 cents each.) I pour the oil into the pillow case and wait for it to filter through. I stop pouring as soon as I see water or any junk going into the pillow case.

After I have filled up the 55 gallon drum I do a VERY simple mist wash just using a pump sprayer. My hope is that this will balance out any Ph issues as well as further flush out any contaminates. I spray a couple gallons of water over the oil. I spray about a quart at a time, coming back in an hour or when ever I think of it to spray the next quart. After letting it sit for a day or more, I drain the water off of the bottom. I then drop in a heating element and heat the oil to 120* for 6 hours while a small fan blows air across the surface of the oil. I then let it settle as long as possible, anywhere from a week to a couple of months depending on how soon I need it.

You'll be amazed at how much stuff settles out over time.

A few days before I need the oil I transfer it through the DSE recomended filter set up and into a second 55 gallon drum, leaving behind the bottom 6" or so to be disposed of later. Once in the second drum, I heat the oil one more time as above and then let it settle again for a few days. I can't really tell you why I do this, except that I like to err on the side of caution and this is an easy step to repeat. I then transfer one more time into my third and final drum which I call my Blending drum.

On the DSE filter set up I do use a better pump then they suggest and I also wrap the two whole house filters with paper towels. The paper towels can be peeled off when they get clogged and it lets me get more use out of the actual filters. Once in the blending drum, I add the kerosene. Sometimes as little as 10%, sometimes as much as 30%. I add 5% RUG. I add the Power Service Diesel Kleen as DSE recommends, about 20 ounces for 30 gallons of WVO. Instead of the DSE stuff I'm using a 50/50 mix of xylene and naptha at the rate DSE recommends their stuff be used.

If you look at the MSDS for DSE you'll see that it's primarily naptha and xylene. Both can be bought at Lowe's for about $14 per gallon or $6 per quart. That's a whole lot less expensive than the DSE stuff. I've read both that the xylene allows the waterblock filter to catch suspended water and that the naptha allows any water that remains in the fuel to be processed by the vehicle without issue. I have no actual proof of those claims, but I reason that those additives certainly cannot hurt and may help, with viscosity if nothing else.

At each fill up I also add some StarTron to the vehicle per the directions on the lable as an algacide. I put a whole bottle of the stuff in my tanks when I first got started just to clean them out. You can get it at West Marine.

So far everything is working well.
