Cycling the waste motor oil into the fuel tank of a diesel is nothing new. In the mid 80's I tried to talk the terminal manager into a portable system that was little more than a suction pump and filters to draw oil out of the engine, super filter it and dump it right into the fuel tank. With waste oil disposal fees of $3/gallon it made perfect sense. The old Detroits had a peculiar fault that caused runaway engine failures when sump oil was drawn in through the blower seals. The engine would run as fast as the oil flowed in to allow it and eventually would disintegrate from running out of oil or over revving.

Is there a problem if there is synthetic motor oil in your waste oil?

Not for when waste oil (synthetic) is used for heating anyway..........

In retrospect adding motor oil to diesel fuel isn't a bad idea. I've been a mechanic fore over 46 years and I use to start diesel engines with trans. fluid instead of either as it was easer to get and if I had a tired engine it would light off easier. Mixing oil and diesel and trans fluid together makes sense, because diesel is much drier than it use to be with all the sulphur missing and the lubricity of the fuel isn't good for older diesel enjector pumps that weren't designed for them. Drier fuel means less power for the buck and more wear on the enjector pump in my book. More oil to a degree gives better mileage and more energy as in B T U's. Diesel engines are more efficient than gas engines and are built better as they have to be stronger in design. Clean up that oil with a couple of filters, preferably a hydraulic filter and then a fuel filter. Never take oil from the bottom of the barrel where you store your drained oil, and never dump anti-freeze or coolant of any kind or brake fluid, or gasoline or any solvent into it. Or It will destroy the injector pump. Leave the pickup tube two or three inches from the bottom and use a suction screen, the finer the better. If you're in a colder climate it would be a good idea to use a pre-heater for the fuel before it enters the injector pumpafter you have put it in the fuel tank. Let the old engine oil stand for a week or so to let the contaminants drop out, like heavy metals and the like.  Oil is safe to store in the garauge if you keep it away from anything that would start it to burn like a gas hot water heater or any kind of heater that would bring it to 150 degrees or so. Oil doesn't have the fumes like solvents and gasoline at room temp.  Also keep away from moisture as barrels will expand with heat and if there is water standing on top of the barrel as it cools it could draw it in through the threads of the bung if there is no seal and besides you want it to breathe some so pressure can escape slowley. 
Just as diesel mechanic stated, the source of your used oil is the big thing to worry about. If you get it from a shop that dumps everything under the sun(anti freeze,etc..) into the same tank then I would spend more time settling,heating and filtering your oil. Just settling and pouring off the top (Leaving the sludge on the bottom 5-10% of the barrel). Water & antifreeze I would say is the biggest worry.Gasoline and other solvents will have a "washing" effect (No lubrication) and are not good although they will evaporate under heat and time (While stored in vented contaner). Brake fluids come in glycol and silicone based. Most are glycol based (Polyalkylene Glycol ether or Polyethylene glycol monomethyl borate ester). Glycol based are hydroscopic which means they absorb water. Typically there is not a large amount of brake fluid in waste oil drums but there could be (brake shop?). I would have to do more studying on this to give a accurate answer as to if the brake fluid itself (W/O absorbed water) is actually damaging to the IP (Doesn't hurt brakes), but neverless I would avoid it due to the fact it is very hydroscopic. ATF is a great source of fuel however. Many transmission shops will do a "flush" on tranny's. When they do this they stick a hose down the fill tube then pump out all the trans fluid. Then add so many quarts, then pump out,then add again,pump out,until clear. This process uses a lot of ATF. And for how much dirty ATF is pumped out 2-4 times that amount in clean ATF is wasted. As a result the waste ATF is typically very clean. Now if they dump that into its own barrel (You can talk them into this, I have!) and not will the motor oil,then you have a good source of fuel that does not take a lot of pre-filtering,heating,or settling to use.
Any way you get the stuff if you can somewhat control what is being dumped in the container by either working some deal with the auto shop or however, the better of you are. It gives you more peace of mind knowing whats in the mix!

Thinking of buying a diesel truck and burning uned oil. How many miles have you run your truck on used oils? What % used oil do you run? How does it work in the winter? Any problems w/ injectors, pumps, filters etc? Any feedback would be appreciated

Used motor oil can be blended in to diesel fuel

Amazing how someone who can't even spell wants to try to tell us that used motor oil is a scam. What a fine display of intelligence. Oil is a liquid hydrocarbon product that can be used for motor fuels, lubricants, hydraulics and burned for heat. Synthetic oils are nothing more than chemically altered liquid hydrocarbons. Burning any hydrocarbon requires understanding of the feedstock and the combustion byproducts. Hydraulic oils like ATF are laden with additives, just like motor oils. Many trucking companies blend waste crankcase oil into the fuel as part of the oil change process. It gets rid of the oil, which burns in the engine just fine, as well as the liability of handling it as hazardous waste. Running an engine on straight oil is questionable. Mixing it into known suitable fuels has been established practice for 50 years. And for the 2nd grade dropout who wants to make us believe this is a scam, a scam is a fraud perpetuated by someone who wants to trade something of value and offer something of misrepresented value in return. Since nothing more than academic knowledge has been offered here, somebody better stop playing around in areas they are not prepared to discuss intelligently.

Hey, Arbogast, I just read this entire thread b/c I was thinking about buying that $1,000 kit to make diesel fuel out of waste motor oil. (You guys may have just saved me a lot of money!) It's at http://myfastfuel.com
One of my customers bought it and said he got his payback from fuel savings in about 6 months.
I think the poster who has no command of English was referring to plans for a kit that he bought online to make a "diesel fuel convertor". I didn't understand him to mean that "using oil as diesel fuel" was a scam. I think it was the plans he purchased.
From what you guys are saying about settling and pre-filtering before use, that kit isn't necessary at all. Water is heavier than oil and WILL settle to the bottom of the barrel or container, as will pieces of metal.
Oh, one other thing: Don't go 'round TELLING everyone you're doing this. The State will come after you for Road Use Taxes. According to my customer (above), one guy who bought that kit was sued by his state for $2,200, the amount they figured he owed for Road Use Tax.
Best regards to all! and thanks for the advice!

I recently bought an 83 Benz with the intention of converting it to run on grease. I have the kit 80% installed but the idea of also running the car on a diesel/oil mixture is attractive as I have access to that as well. Someone suggested using a 10 micron filter for straining the oil. Any thoughts on that? I also have access to #2 fuel oil. My understanding is that a diesel can run on this but since it is dyed it would give off a tell tale exhaust plume. Any thoughts on how to minimize or reduce that?

I thought the dye trick was to indicate "untaxed" fuel but didn't think it made any changes in exhaust evidence - dunno....

Very interesting reading. I have a mobile oil change business that i do part time, and am the only one who has changed the oil in a fleet of 100 vehicle's. Therefore, I can control what is in my used oil. I think that I am going to give this a shot. I will let you all know.

Well guys, heres the facts.. I have been making bio diesel from used cooking oil and mixing it 40 to 50% used and filtered motor oil and tranny fluid in my 2004 Silverado since brand new with no ill effects. The truck now has near 200,000 miles on it. The oil that I change from the crank case is very much cleaner then using straight diesel, which in comparason to my neighbors 2004 Silverado. He refuses to burn any alternative fuel. (his loss). My suggestion would be to get some tranny fluid, filter it with a guaility filter and add 25% to your diesel, you will see it will burn very well, So add more till you can tell a difference in performance, I find about 60% the truck starts showing poorer power. I use straight Bio when I can get the used cooking oil, when oil gets hard to get I start cutting with tranny and used motor oil. Here used motor oil and tranny fluids are harder for me to get. Good luck. Feel free to email me if you need any help with your formula. bluesdaddy@hotmail.com

Well, I am very intrigued, and a little disapointed that I didn't know about this sooner!
To think of all the oil changes that I've done in the last year on our vehicles that could have offset my fuel costs makes me sad!
Right now, where I live diesel costs around $1.40/LITER (a little over $5 a gallon).
Could I go to Walmart and buy there cheapest oil which is probably less $4 a gallon? It would theoretically be perfectly clean oil. If I mixed this at say, 25% it could be a considerable savings in the long term.
The savings of course would be even greater if I settled, filtered and then used all my used oil from our vehicles.
What do you think?
Thanks!

A friend of mine also bought the $1000 "Toby" kit from myfastfuel.com. It is a very rudimentary setup and can be made for less than $200 yourself. My friend has been running 80% used motor oil/20% red fuel in his 2000 Cummins and it loves it, more power, better gas mileage. He's also been putting it in his wife's Jetta TDI at a 5/95 ratio to start out and she noticed right away it had more power and better mileage, over 60mpg! He also runs it in all his heavy equipment which run better on it as well. Apparently Caterpillar makes a unit that pumps used motor oil directly from your equipment, filters it, and pumps it back in the gas tank, but it costs $15,000.
I ordered all the same stuff to make my own tank with pump and filters for a little over $200. I'm going to try it in my VW Touareg V10 TDI and start at a 95/5 ratio as well. Which isn't much of a savings since it's only 1 gallon per 20 gallons of diesel, but hopefully I can get it up to a 50/50 ratio without setting off too many sensors.. I'll post my results in a couple weeks. Feel free to email me if you are interested making this setup yourself.

WE HAVE BEEN DOING THIS SIMMALAR PROCESS BUT RAN INTO A PROBLEM. TRUCK WONT START AND HE THINKS IT IS THE COMPUTERS 300.00 FOR TWO, THE CRANK SENSOR AND THE ECM(?)250.00 FOR THAT ONE WOW. WE CLEAN THE OIL MANY TIMES DOWN TO 10 MICRONS AND IF ANY WATER WE HAVE HEATED IT TO 400 DEGREES TO EVAP ANY WATER IT WAS RUNNING REALLY WELL UNTILL HE PUT DIESEL IN IT. NORMALLY WE RUN STRAIGHT MOTOR OIL AND SOMETIME TRAN FLUID BUT I KNOW HE HEATS THAT UP EVERY TIME. please excuse my spelling

So i've been doin the veg oil thing and i'm a big fan. I would think that the waste motor oil would be fine just was getting confused reading the posts and wondered what the answer was about synthetic oils. ok or not?

try using the www.dieselsecret.com product.when building your filter build it to step down to one micron.also prefilter it in a clean 5gal with a mesh screen and one cotton tee shirt whole shirt two layers of cotton.before you run it through your filters and 20 percent diesel-2 which should thin it down.i live in a hot climate so the sun does alot for me. this final product can be used with any ratio of diesel or bio you like and as long as you filter it properly any used motor oil any atf any hydrolic can be used.be sure your oil is free of water

I have been running diesel ever since the first one rolled off the line at Dodge in 89 and have owned 3 since then
I am looking at buying a new 2009 for my last one ( was thinking of used the one I have now for my last one but was very interested in the new suspension and the larger engine
also I only buy the Laramie version the fist one did not have that option just the slt
I was in the service and they have trucks that run on anything that you could run down the line and that includes gas you just switched over to a spark plug setting it lowered the compression but even perfume could be run down the line
or any other oil you could get be it used oil from a used oil after someone changed there motor oil and ATF
also now you can use CNG with diesel or propane also oil from a fryers at restaurants being military you have to be able to use what you can get have to use
so what it comes down to is that the fuel not gas in a diesel can be used as long as it is not to thick to run down the fuel line and it is clean so you Eng will not get plugged up and if you have a dodge nd use cat injectors it is 10 holes not the 5 so you can really get it clogged up
and if you live in a cold area the use #1 fuel but I use to drive trucks and there is a trick 1 can use so you do not have to use #1 fuel for every 50 gallons add 1 gallon of gas and it keeps thing from jelling and you still keep the lube from #2 fuel
and the person who wrote that CNG is going to take awhile so ppl can have it...but I think seeing that there are adds and city's using this gas so I am thinking there will be Hybrids very soon using this fuel with diesel
So I see that more and more diesel will be used along with CNG 1 is you get water as exhaust so this is a green product and 2 you get more HP and Torque and the best thing is mileage at 55060 mph you will get at least 35-40 mpg ....but if you go faster you get more mpg there have been some that have gotten up to 125 mpg but they changed the exhaust the fuel feed like a fass system a new set of injectors and a lot of air the more the better
also ppl have said it is corrosive ....false.... your diesel will take care of that
but all in all you end up with better pricing and testing new ways to get better mileage and have clean air can not be a bad thing
