"I see why you are using paper-based pre-filters but does that really help with the cost of not buying filters in the first place? The centrifuge should be able to clean up to .5 micron, so a filter should not be necessary. You might need to clean the centrifuge a few times, though. "
The pre filter is mainly to strain any large particle that may be in my source barrel ie. the oil I am getting from the dealer or my friends. I do get some oil with large nastiness in the bottom. This way is easier than screen filtering into my centrifuge tank. I spent like 5 bucks for those cheap oil filters and haven't changed them yet. I try to keep the oil thats in the centrifuge tank as clean as possible even before it goes through the centrifuge, because if not there will be some junk that will settle to the bottom. Although it shouldn't matter because my pickup is a couple inches above the bottom, but I like the piece of mind that all is clean.
It may seem like its a lot of extra steps but it isn't really and I smile every time I fill my truck tank.
I guess if they are cheap and don't need to be changed much, it still beats the pants off $4/gal! When I buy a place (again) and get out of apartments, I will be setting up a UMO/UVO processing unit. I guess I could use filters until then and do small amounts.
Is it true that I shouldn't burn oil from a diesel or is that hogwash? I tend not to believe just one person's opinion. I have 3 gallons of UMO that came out of my truck. I was thinking about filtering it and running it. $12 of free fuel, sure.
