I burn waste oil in my truck. I filter it through 2 'sock' filters, a 15 micron filter followed by 5 micron one. They're easy to find online for a few bucks. Obviously that wont get water out of there, but if you know theres no water in there to begin with, that doesnt matter. Only use oil that you know exactly where it came from.Hello,
Thanks to everyone who replied to this post. First off I want to just restate the fact that the company I was referring to does make large quantities of B&C oil from used engine oil. With that being said I don't think that a clean filtered product made from used oil would be anymore damaging to the environment than any other. I do agree that veg oil may be overall better but that is not something that i'm looking for. I am just trying to figure out what the best process would be to clean out as many of the contaminants as possible. If I can figure out a process this would be used for a fairly large amount of oil so the savings would be spread across much more than just a few gallons.
Thanks Again
I wouldnt go spending wads on a centrifuge especially if its just going on your b&c. The tolerances there arent even in the same league as inside an engine so your oil doesnt need to be as good.
