Waste oil as Fuel

[Fred Mc]

I just read an article where waste oil is mixed with diesel and used as as fuel.

Is this a bonafide procedure or??

go to this site has good info http://www.frybrid.com/.im going to start using a centifuge from diesel craft to clean oil before i burn it

[tekebird]

waste oil has been used for furnaces for a long time...need special equipment though.

as far as cetrifuging waste oil to clean it....I doubt that all the bad stuff other than particlates would be removed.

For use in a furnace the only thing needed is an oil filter in the feed line. Oil is then run thru a high pressure pump and then thru an orifice to create a spray. Works great. I saved at least $1,000 a month on my fuel bill when I installed one.

I have read that the metallic particles in the waste oil would harm a diesel engine.

I've known farmers to filter waste oil and run it through their tractors mixed with agri-diesel, but I have no idea what longterm effects one might expect,

I was leased to trucking company that put waste oil in the diesel. Every week or so they would pump 55 gallons through a filter system, the filter was approx.
18 inches by 3 foot. They would pump this into approximately 10,000 gallons of
diesel. It came out of the pump a cloudy gray. I ran this in a Big Cam IV Cummings, and had no problems with filters or injectors.

To see some of the many lengthy discussions that have taken place here before on the Waste Vegetable Oil topic, do a forum search on WVO.

[tekebird]

are we taling WVO or waste engine oil WEO

[HighTechRedneck]

are we taling WVO or waste engine oil WEO

My mistake, rereading the OP and definitely BUR's post, the topic refers to WEO not WVO.

[Paso One]

The more common is WMO  which is (waste motor oil)  The other  common term WVO which was stated correctly at Waste vegtable oil.  Have been following the yahoo groups etc for alternate fuel for building heating.  My 5000 sq ft shop will be heated with a boiler that also includes a WMO attachment. DML 's figures are accurate. Filter or centefuge cleans up nicely for burning. I'm not ready for use in engine but many are doing it.

Guys this is a no brainier DD tells you in black and white in sec 13.3 page 7 of the book DO NOT use  waste engine oil as a fuel additive in the engine   fwiw

[josephgranzier]

I liked that "almost biblical reference" black and white in sec 13.3 page 7- I would be afraid of any harm to the injectors , clogged filters ect ect 
Even the post before - adding 55 gallons to 10,000  - Did they really save that much ?
I know that the $4.00 plus is a lot and we would all like to save money- it seams to be the definition of a false economy .
I'm tempted from  time to time to fill our one truck w/ heating oil....... but haven't ...yet.

They say "not to use" which does not mean you can't use. It does mean that if you do use WEO/WMO as an additive in the fuel that DD can deny any warranty claims connected to the use of WEO/WMO. DD will sell you replacement parts all day long, but won't replace them under warranty.

I'm not an expert, but unless you put "a lot" of miles on the engine you will probably be fine as long as you filter out most of the nasty little bits (maybe down to 5 microns?). If you want to see what happens, take apart enough of your current engine to and inspect it and determine current condition. Put it back together and try out the WEO/WMO for a while (1,000 - 5,000 miles?). Take apart your engine and re-inspect to see what's happening. My educated guess is that the injectors would take some abuse and the cylinder liners and rings may score or wear a bit faster. Electrically controlled/operated engines/injectors may fare worse than MUI engines.

If the engine is "old" and needs a rebuild anyway who cares? Experiment, your going to rebuild it anyway. If the engine has been recently rebuilt and it's a 500,000 mile engine (post rebuild) who cares? Experiment some, and see what happens. So maybe you "lose" 10,000 - 20,000 miles of life. Are you going to rack up 500,000 miles on the engine in your lifetime? I'm pretty sure I wouldn't. I know my (mostly) daily driver '96 Dodge RAM with the Cummins B-series just ticked over 268k miles, with 213k put on by me in the last 10 years. It'll take me at least another 10 years to get close to 500K, although I need to start thinking about a rebuild...

I'm seriously considering making my own Biodiesel, but I already have too many projects going right now, and I'm tired of not finishing any of them. That's my excuse and I'm sticking to it! Until next week when I'll have another one.

Seems that many, many people, sadly including me, too, have lost the spirit that has made, and will continue to make, this nation great. We are too easily told (and willing to accept) what we can not do, rather than find out what we CAN do. We are also very quick to shout down people who are willing to try new things, and in fact enact laws to actually try to stop them! Why is that? Does it scare us that someone is willing to challenge the status quo? Does it threaten our perception of the "proper" order of things? Are we afraid/scared/threatened to find out that what we may know may be "wrong?" Change for the sake of change isn't always good. Change because a better way is (re-)discovered is good.

Just adding my fuel to the conversation.

That is a great thread Richard. Lots of good info.

As far as a centrifuge goes, if you are going to use any sort of waste oil , WVO or WMO, as a fuel, and you plan on using a decent amount of it, get a CF (centrifuge). You will get about 300.00 - 400.00 max wrapped up in it, but it takes everything out, down to .5 micron. That is "point five" micron, not five micron that people typically shoot for. It does an excellent job of cleaning. And it de-waters it also.

  I may be buying a WMO furnace for my newest shop (Hopefully a Hot Rod shop) and from what I hear is that they are really good  - not all created equal - but they can tend to go thru filters. Altho I built my centrifuge for WVO to be run in my bus and for the fuel oil furnace in my studio, I am going to be running it to clean WMO for the furnace in my new shop.

  Definitely give it serious thought!!!!!!!!!! By the way, here is all the info you could possibly ever want on a CF:  http://biodiesel.infopop.cc/eve/forums/a/tpc/f/159605551/m/2001011761
  This is a great site for WVO, SVO, and Bio.
