So far I only have one WVO source and I consider it good. Most of what I get looks like that of your "good" cubbie. But they also give me some crap. This is because they simply give me everything they drain weekly in the original 5 gallon pails. So my first step is always to separate the good from the bad. If it looks like Pepsi on top it goes in the "good" stack, and if it looks like gravy it goes with the "bad".

Then, settling becomes your best friend. Eventually, the "Crap" has some good stuff that floats to the top, which I slowly siphon off until the gravy appears. Then, I pour all the leftover "gravy" into one big pail, and let it re-settle. And so on.

Then I take my good stuff and filter it like mad- first through cheesecloth, then through a triple paint-strainer, and finally at least one pass slowly dripping through a home-made toilet paper roll filter. This is finally tested by pouring the finished product through a fine mesh funnel strainer. If the funnel blocks up, or if I feel any grit on the strainer when it's done flowing, then I drip it through the toilet paper again.

I end up with a clear dark amber canola, which I mix 5 parts with 1 part Naptha camp stove fuel. Then this mixture gets blended in my tank with Diesel fuel- right now about 2 parts Diesel to one part WVO. When the hot summer sets in, I will try 50:50. This is my first year using WVO, so I'm still experimenting. I may do a heated tank conversion for fall and winter, but I'm more inclined to use my WVO in the furnace tank- that's where I really need the fuel savings- and run the Benz on straight Diesel in the winter.
