I'm wanting to convert my 2006 Cummins to run Waste Vegetable Oil. I've done some research on it, but I would still like to get some more info on the subject. Has anyone here done the conversion? How does your truck run and how complicated is it to convert the WVO into a runnable fuel. Any info you have on this subject would be greatly appreciated. Thanks.

 

I settle WVO for a week after I get it, then separate the sludge from the thin amber oil, then I blend gasoline with it at 20%, then leave it to settle again for another week, then separate the sludge from the thin amber oil again; then I filter it down to 1-micron in a bag filter. I have been doing this in an unmodified 6.2L DD engine for 6 years. It runs fine on it, and the fuel should run on any diesel engine with no issues down to 0F (-18c).
