Used motor oil for fuel

[Ram Rod]

Read a post on power stroke nation and they are using 50/50 mix diesel and waste oil what do you guys think?

Waste Oil

I would not run 50/50

If you clean up the waste oil a little ie let it set and only tap the clean oil out of the top of each jug of oil.

I have a cless 8 truck Cummins N-14 with 2 - 125 gallon tanks and after I change the oil 11 gallons I add 1 gallon per tank in order to get rid of the used oil.

I keep extra fuel filters with me JUST in case.



Start off with a little and keep adding and see how you like it.



Good Luck

How about this?

HI All,



With the high price of diesel and the fact that I use so much of it I have been looking for ways to save $$... . Everything from making Bio or using WMO, To Running Red... . BUT something that caught my eve was this eBay ad from Australia... .

(item # 270235383014)... . Has anybody tried this?... I asked my father about if it seems reasonable (he is a chemist) and he said if you heat used motor oil and condense it in a fractional distillation tower it is possible..... Has anybody here actually tried? I am curious but really hate to spend so much on plans that may or may not work...





This was recently posted in this forum. I am highly interested in this but cannot get a reply from the guy. A little skeptical about buying something from another country off e-bay. What do yall think?

Go to e-bay australia, then cut and paste the item number into the search box. It looks interesting and I have a great continuous supply of used engine oil. What do yall think?

 

[jcarey]

I looked at ebay au, and the add seem a little on the snake oil side.



I also noticed that the item is no longer being offered.



I found what I think is their web site: HOME



Here's one of their items for sale:



Wood Burning Gas Producer

Is petrol becoming too expensive? Is petrol hard to get? Why not run your car on wood? These plans will show you how.

 

[Dieselnut59]

That is them. I am highly skeptical. There is a e-mail comment on there from 2005 and every comment talks about the "plans" but nothing mentions the end results? All the comments are about the "plans" but no one has built the thing and had any results?

I sent them an e-mail last week and never heard back from them.

Seems like a GREAT idea. Can someone please come up with a way to do this HERE in USA?

Can you do this with used synthetic oil too? (I use synthetic in my motorcycle).

 

[jcarey]

It seems to me there was a problem with using synthetic oil, but I can't remember what it was.



If you do a search on the 3rd gen forum, you might find the thread.



Just remembered: it seems someone who tried to mix synthetic with their diesel had a liquidy exhaust, which they deemed to be from the synthetic oil.



I tried to do a search, but couldn't find the thread.

When I had my truck, a buddy of mine used to put the whole oilchange in his tank. He had a 100 gal tank, and it was a Mack ESI+ whic is 56 quarts. :{

I never did this.

Hey Guys,

I did buy the plans for making the diesel from waste engine oil and I hate to say it but it was not entirely what I had hoped for... . I will wait for the CD to arrive to see if it helps any... .

Hello Andrew



Do they want you to filter thru some sort of beads ? or mix in some chemicals that only they sell?

Guys,



This has been beat around before. However to get to my contribution to this thread, Go to Oil to Diesel Forums - Powered by vBulletin



I didn't go to ebay and check out the item, however I'm guessing it's the re-refinery offered a couple of years ago out of Australia.



Heat used motor oil to around 750 degs. f, condense the gases just right and you have diesel (among other things). It does work, but as is often the case, the devil is in the details.



Good luck,

[AndrewKing]

HI,

Yes "the devil is in the details" and the plans don't even tell you sizes etc on how to make the refining plant... . I am hoping that the CD i get in a week or so will have more details..... Moparguy you did hit the nail on the head... . I wished it had specifics on how to build the thing... . the general idea is sound (but one could just google fractional distillation of crude oil or similar and get pics of how to make the basic distillation tower... of course the details are key why isn't really provided in the plans..... I'm waiting for the CD but until then I am setting up a filtration station (diesel Craft centrifuge) to run WMO... .

Well, Ive been touting how Ive been running on a lot of used motor oil lately. When I just pulled the injectors to do an upgrade I found a lot of carbon deposits on this set as compared to other sets that have been in the truck longer. I "think" most of it is due to running almost rediculous amounts of used oil (gear oil, transmission lube, etc) It always ran fine, but i think it does leave deposits in the chamber and exhaust track that cant be good. . Next time, itll be a lot more diluted. just something to think about.

 

[Bob4x4]

Phil, how's the smoke level? I find my old 12 v even hazes at idle w high percentage of wmo,but not as much using used atf.

Andrew, if you have time go to the site I linked, click the top forums button and read all the post under "Oil to Diesel Systems", or at least scan the majority and you'll pick up a ton of info.



At one time I was all hot to trot to build a distillery, however the burner issue, as well as questions on how to build a effective tower have tempered my enthusiasm.



I just don't have time to do the grunt work of experimenting trial and error at this time. I'll add when I can as others work out the details, and will gratefully pay for a set of plans when a safe, semi-auto plant is worked out.



OilGuy could pull it off, if he'd just stay focused. He has however bought a 08 Dodge Cummins and is reluctant to run anything other than store bought fuel. Can't say I blame him, just wish he'd buy a old 12V and get back to tinkering.



Good luck,



RJR

Phil how much did you put in at a time? I don't do more than 10% o my tank on the '98 12v. No haze at all idling and no more smoke than with straight diesel (light haze at WOT)

 

[BigPapa]

I'm with Vaughn, I'm adding between 2-3 gallons on a fill up, motor oil ONLY. No transmission fluid, gear oil, or synthetics. No smoke, no more than normal, and no other problems I've seen.

As to this deal Dieselnut59 is talking about, with guys out there talking about getting fined for stuff as stupid as picking-up and transporting WVO, imagine how they'll look at a refinery in the back yard.

Mercedes Benz produced some cars that ran on the gases from burning wood in the '30s, I think.

 

[AndrewKing]

Thanks Moparguy... I'll check out the link.

Bob, almost same here, not sure how much haze , but it was to the point to where you could smell the burning oil.

Vaughn, The most run at a time was about 6 gallons mixed into the 66 gallon aux tank. It was a mix of engine oil, gear oil from front & rear diffs, (ha), gearbox oil (penzoil syncromesh), ATF from the txfr case, and the rest was the old type #2 diesel. The system is plumbed to use the OEM carter pump (still mounted on the motor) to circulate it through a strainer before the pump and frantz filter afterwards then back to the aux tank, or turn the valve and it goes into the main. This stuff was circulated while driving for about 2 weeks, then slowly started transferring it to the main. Towards the end it was almost exclusively running on the blend from the aux tank (6/60 or almost 10% used cruddy oil). Ran perfect. . But you sure could smell it. Might be due to the gear oils. Doubt it is from running a lot of biodiesel, but not sure. Will probably set a rule of thumb to be 1/50 max wmo from now on.

I had spoken with a well-known VP rebuilder in this forum, and his opinion was it would not hurt the VP, just stain the insides black. (added: He was referring to "well filtered" oil)

After seeing the increased carbon deposits on those "mild" 275's, I'm pretty sure that was overdoing it a bit. .
