I give my waste oil to a friend who is an over-the-road trucker. He has no qualms about dumping a couple of gallons in that BIG fuel tank and running it in his big truck.

I'd rather give it to him than risk my VP44... At least until I move to Colorado and get my garage outfitted with an oil-burning heater.

If I remember , one of the average smallest fuel filters is about 7 micron [ I mean stock , what the builder feels is the max allowable ] .
So that as to particles , should not be a problem , but we seem to be a bunch that likes to make things better , so some after market filters going around 2-5 micron , then by pass & centrifuge going sub micron , the particles being out ?
Then other issues are PH balancing , water ect. , this is just one more reason I went looking for the 12 P-pump .
I know I have the link for fuel recommendations , but have so many , that I can not find , there are about 4-6 things that were allowed in the P-pump engines , oil being one of them , but filtering , water & PH should be addressed .

Burn 1200 gal/year in my Reznor heater, shop 8000 sq. Get 3 loads of ash out of it during the season.

if diluted properly I think the pH would be of little concern, but there is probably a lot of junk in there that would need to be filtered out.

There are several centrifuges on the market that will filter to 1/10 of a micron for under $300. One unit will filter 55 gal of oil in 2hrs. We can fight the oil companies by recycling smartly. It will take some time,money and effort but if we keep paying their prices they'll keep charging more. Centrifuge co. Spinclean also dieselfuge

I use a centrifuge for WMO and WVO and it is interesting the amount of crap that is removed.
I would highly recommend this type of filtering. No filters to change only bowl to clean out. Will remove water from diesel.

I have done a lot of reading and searching on this topic. I am convinced that centrifuging is the way to go. I am getting set up to do wmo/atf/etc. I plan to gravity filter thru a series of filter socks and then centrifuge thru an ACME Juicemaster juicer modified to become a centrifuge.
I saw/read about it somewhere recently. Sorry I don't have a link to it right now. Will post it when I find it.
Anyway, this juicer appears to centrifuge efficiently from the pics, but I wonder if it will just take longer since it only turns @ 3600 RPM. The "REAL" centrifuges turn at 7200-8000+ RPM. They are probably quicker and more efficient.

Do you heat your oil before you spin it in the centrifuge?

What kind do you have?

Thanks for your input.

Can be made out of everyday shop materials and hardware store parts.

I would be interested in those plans! I'll try it.
