RE-using motor oil - Steel Soldiers::Military Vehicles Supersite

I've got a centrifuge coming and will be running WMO eventually.

Also will 'fuge and blend in old tacky diesel fuel when I clean tanks. Figure on treating the salvaged fuel with preservative and fuel additives just for the principle of it.

But at the same time, the centrifuge is great technology for cleaning motor oil to treat it and then re-use it. It's more cost effective than burning it.

Anybody out there doing that, and know a good process?

Thanks.

Where did you get the centerfuge system from and how much it cost - if you don't mind me asking?

TexAndy · 10-11-2009, 14:03

ditto. I looked at the dieselcraft stuff, but they seem too expensive for my tastes.

Would you mind posting pics when you get your centrifuge? I've got a few ideas for making my own I'd like to try...

try looking at these guys. they are a ground up kind of group and have a build you won option. just something to think about if you want a centrifuge. i am thinking about getting one of the center units and building my own i am sure my unk Tim has all the rest of the parts i need. Simple Centrifuge ...putting a centrifuge in every garage!

Hope this helps

God Bless and thanks to all of you who openly share your knowledge and wizdom

Avengeusa is a member here and he sells centrifuges:
Wolverine Technologies LLC Wolverine Centrifuge for WVO, WMO, Biodiesel

I've ordered the Wolverine system. Just don't have the time to put one together myself.

Besides, I want somebody else to grouse about the first time I fling oil all over myself.

WMO as fuel makes sense, but I have a bunch of deuces that need their oil changed or cleaned, and I think cleaning and replacing additives makes a lot of sense.

This thread interests me. I have a pair of 18" Merco centrifuges here at work, that I use to get sub-micron sized products, but my interest is about the cost effectiveness of using centrifuges verses filtration. You would have to be processing an enormous amout of WMO to pay for this process while still needing to build a filter system on the feed side of the centrifuge. How much WMO are you processing? How does this clean additives? Are you setting this up as a continious process? You can pm me details. Thanks Mark

I was thinking about casting an aluminum bowl and machining it down to tolerance myself.

Cost effectiveness for an individual hobbyist for something like this would be around $300 for the entire setup, I think. At that price, assuming you get your oil for free and you don't count your time expenditure as anything, you're at the $1/gal once you've filtered 300 gallons. And that's a reasonable amount to filter over a year or so. With diesel at 2.50/gal, 1/gal CLEAN and RELIABLE used motor oil is a worthwhile deal, imo.

Of course, if you run fleets of commercial trucks for a living and you have a way to USE all the oil that the Wolverine or Dieselcraft centrifuges can put out in a day, and you have a source for that much free WMO, then by all means... $900 or $1500 on one of those systems is money well spent.

I have about 800 gallons saved up now, waiting for a way to filter it all. Mine is gonna be fuel though. I could have much more, but I've ran out of storage space. Need to find a source for some cheap 250-300 gallon totes.

Okay, I admit it, I'm a neophyte to this centrifuge thing. Just what exactly does a centrifuge do for you that a good pump hooked up to a series of filters in series won't do for you.
