WMO Info

I get nice used WVO from a local store. Its clean and bright with a slight white haze. Best way I found for preparing it is to First let the WVO sit still for a week- heavy contaminants sink. Than Transfer the top cleaner stuff to another container. Next I add anywhere from 20-40% Kero and allow to sit for a week or so. This does 2 things: one it thins the oil significantly and prevents thick sludgyy WVO even in cold weather and 2 Kero seems to make all the non oil contaminants sink to the bottand forming a layer of whitish brown sludge leaving only clean and clear WVO on top. Also adding Kero creates some kind of an emulsifing effect that prevents the formation of fatty solids. In my tests diesel mix did not do as well for cleaning up the WVO, not sure why.

There are provisions under RECRA Managing Used Oil | Wastes | US EPA for what is know as a "conditionally exempt small quantity generator" or CESQG that appears on documentation for the products recovered from these generators. The regulations are very clear about chain of custody for the recovered products regardless of generator however the CESQG regs are pretty loose compared to large generators such as Jiffy Lube.
What does this all mean as far as using RMO (recovered motor oil, never "waste")? You probably can find some supply from CESQG sources but be aware, federal and state regulations are very real and if someone from an agency conected to the recovered product monitoring starts poking around it could get ugly. The main problem is the end use, you would not be a recognized end user registered with the EPA and the supply source is not a registered fuel generator, then you may run in to the road tax problem. For those of you making process rigs to clean up you oil to use it for fuel, be aware the sludge and water are very real "waste streams", choose your proper disposal methods and stick to the regulations, they don't joke around about this stuff.
Bottom line, quietly find some small generators, make a deal with them and keep it to yourself.

Gotta agree good advice.

I'm collecting wmo for use in my 6.9. Can I use this in my Mack truck as well? E7-427 engine.

Ugly question, but what exactly is the proper disposal method for the sludge and water?

Maybe I just take it back to the tank at Autozone ... but that doesn't seem right.

I'm not very concerned with running afoul of the law -- I just really want to do the right thing and taking it to the local liquid/hazmat facility doesn't really give me the best feeling that it would be disposed of properly. Even if it was, you have to label it and declare what it is ... and those questions might better be avoided.
