Hi all, Does anyone know If it is possable to convert used motor oil in to a useable diesel type fuel. there is a web site that is selling the plans to do this? Thanks

Hmm, interesting site. I've heard of ways of doing something like this. Hear about people getting used cooking oils from mcdonalds and Chinese restaurants then filtering out the left over food, and running the vehicle on this oil.

Also did you notice their diesal price is per liter, at $2.00 a liter is quiet step.

I am leaning towards a modified hybrid. Heard a scientist has been building them since the 70's and one of which gets a staggering 250 mpg's..... Also another electrical engineer modified his Toyota pris. To get over 80 mpgs by adding more battery power. Looks like the hydrogen future is a decade or so away, but the hybrid plugins could be right around the corner.

Where I live used motor oil is burned to heat greenhouses! Some must go elsewhere but most of it gets used as heating fuel. It's mid August and only 56F outside right now!!!!! Come visit in January! With a smile from Tom

I do not know about the motor oil 1. it is dirty, i would not want that in my car, probably will clog the injectos and fuel fiters, plus little chips of metal and steel, plus impuritys like brake fluid, engine coolant that can kill expensive engine controls. I think the cooking oil is a better idea, by the way I heard you have to add a small amount of lime to the cooking oil. I also read an article about , was it Scotland or someplace that the government gets a lot of it's fundings from the diesel it sells, so the people started using cooking oil from the hamburger places ans diesel fuel sells dropped, so the gov forbid using cooking oil, strict fines , they have police going around smellining tail pipes to see if they smell lile McDonalds. Actually I think thats the way it will be in the future, the electric cars are just a stop gap. I predict that in the future all cars will be diesel and running on vegatable oil, and who has farm lands that can produce all that veggie oil...the USA, we will be the new MIDDLE EAST, all the refinnery towers will say WESTON on the side.

I have ran used motor oil, transmission fluid, hydraulic fluid, dielectric fluid,mineral oil and etc.. in my 1995 chevy diesel. A diesel motor will run fine on any lightweight oil. When running used motor oil it would be a good idea to either mix it with diesel or run it in a heated separate tank (Same as WVO) the reason why is th viscosity is thicker than diesel and is harder for your lift pump and IP to pump (Potentail wear) at 160f all oils flow the same as diesel. as far as filtering, make sure no water or big chunks of anything is in it and pour it in. Anything that passes thru your main fuel filter is small enough to pass thru the injectors and burn up in the cylinder, blow out tailpipe. It will NOT plug your injectors! After a year of running this stuff (Mostly used ATF) my injectors look clean as new. I cannot run used motor oil straight as in the later model chevy's they have a optic sensor that is for timing. Unfortunately they put this device in the fuel itself and it cannot read correctly in black oil. Ford and Dodge should be fine.(Or early GM's)Everytime you do a search on this subject people will tell you how bad this is on your motor.Plugged injectors, ATF is corrosive (Don't want it in my tranny then either) are some of the things said. Once you de-bunk all that then the issue of the enviroment comes up even though if you look up waste oil burners (Which burn at a lower temp than a diesel combustion chamber) they all tout their product as "enviromently friendly" and they are EPA approved! I could go on all day but I think i'll just go fill up with some more used ATF and be on my way

Hello,
I am not too familar with sites like this one however I have been researching alternative fuels for diesel engines and your posting caught my eye. I have an F250 2000 yr and have considered all the alternatives you listed however have not had the nerve because of all the talk of conversion of the fuel systems etc. I would love to talk to you about your experiences. Please contact me at the e mail address yltnarb@hotmail.com. I appreciate any time you can spare.

just wondering if you had to do anything special to the system and if you use the veg. oil do you have to add anything to it or can you just filter it and run it

Lye, not lime. :)

One CAN use straight veg oil if it's heated. Main problem there is the glycerin will clog filters, injectors and gummy oil. It's best to just refine veg oils as biodiesel.

Hello.New here...I have a 1981 datsun w/sd22 nissan motor.Wondering if I could run atf in it?It won't eat hoses?I looked into vegi-fuels-seems like alot of schlepping glop around-I'd appreciate any a
and all advice.Thanx brew
new to the net,so you send info to my Edress it would help...

Did you just add them undiluted? Please explain further.

Used Motor Oil
Transmission Fluid
Hydraulic Fluid
Dielectric Fluid
Mineral Oil

My brother and I both run used motor oil in are Ford trucks. I have a 91 f350 with a plain 7.3, He has a 97 powerstroke. We mix it 50% old oil with 50% fuel in a barrow , let sit for a day or two and pump though a filter and mix that with more clean fuel in the tank to make a mix no greater then a 4 to 1 finel mix. When you settle out the dirt your filters last. You can also use the most dirtest oil you can fine. We both get more power and better mpg on this mix. No troubles at all. No smoke. No bad smell.

I am sure it is possible to turn used engine oil into a fuel, but the process would be rather complex. Similar to refining crude oil, distilling, cracking, etc. This would only work on conventional oils though as synthetics are desingned from the ground up to be lubricants and nothing else.
As using unrefined oil for fuel, I wouldn't do it. I would think the process of burning oil would create a lot more soot than normal fuel due to the heavier residuals in the oil not burning completely. Not to mention making sure you get ALL the particulates out of the oil before putting it in the system. You will be changing your fuel filter a lot more often. Some people also have emmissions test to worry about, if you are burning oil then you will most likely fail. Emmissions systems are desinged to handle burning fuel not burning oil.
If you want a good alternitave fuel, look into used cooking oil. It is very simple to refine and cost effective to produce. Plus it it tried and tested and works well, some say it works better than regular fuel. I have helped a couple of people design and build cooking oil refining units in their garages and they can produce upwards of 50 gallons of bio-diesel in one batch. If you can get the cooking oil for free you can produce bio-diesel for about 50 cents a gallon!

Is not diesel fuel a type of oil? Burning oil at 600f+ burns all residue. Read this from clean burns site on their waste oil burners. They do not even burn at the temp of a diesel combustion chamber and they are EPA friendly.http://www.cleanburn.com/...tage/environment.htm As far as passing emissions don't run it at the test if your worried(most diesel fuel doesn't pass).And as far as fuel filters I don't dump any kind of fuel in my tank without filtering it first. That is just common sense (duh)!
Most "tree huggers" freak out on this subject. And of course the big oil companies don't want you to do this either so they will tell you anything (without facts)to stop you from doing this. I am giving you facts. So while everybody keeps blowing smoke up everyone else's @ss, I'll be blowing my EPA friendly smoke out my tailpipe!

The way to go guys,
About 30 years ago trucks were converted to very slowly add the hot engine oil to the fuel. A clean oil tank would keep the oil pan level constant, just change filters. No oil change.

I am now burning veggie oil in my 99 F350 works great
i mix used engine oil ,diesel and injector cleaner .
Can i do the same with used engine oil?

last msg was a typo i burn veggie oil can i do used engine oil the same as veggie oil??

While I have never tried any used motor oil in my Jetta TDI, I have always used it in my tractors. In fact every type of oil used on a tractor goes in the tank when it gets changed. Well actually it goes in the pup tank with the ag diesel and filtered as it is pumped into our various tractors.

I have an 97 f250. I burn a 50/50 mix of transmission fluid and diesel. No power loss with a little smoke. I had to replace the fuel pump after about 10,000 miles of burning this mix. Has anyone else experienced any fuel pump problems?

You get better mileage out of it, but it's not good for the environment.

I am very curious as to what caused your IP failure. I can guarantee that it was not the ATF. I have many vehicles that I personally know now that have a lot more miles than that running almost straight ATF with no problems. ATF has nothing in it that will damage a IP (in fact it is the opposite ) if it did it would also ruin your transmission!

I have a 7.3 diesel ford and My run just fine on use motor oil.What I did is heat the use motor oil into a 30 gallon container.let it boil until it get to the point that you notice the seperation of the oil and You have to use your judgement.let get really hot.then filter it using the cloth and then filter it with feul filter the big filter can be purchase at tractor supply.Make sure you scoop out or seperat the dirt and the carbon first before filter it.After you have done filter the oil. Now you get a nice clean oil.Now mix your clean oil with diesel about say 35 to 40 percent oil and the rest is diesel.Then I would filter it again before put it to use.That save me lot of money buying a fuel at the pump.Do at your own risk!!I have done it more then 5 year now and never have problem with my truck.

for gods sake dont put lime in any part of your vehicle... its like dirt only far more abrasive and corrosive

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.

removing the cat converter would fix that problem. Compression is high enough to light it off well and with no smoke under normal conditions. Lugging the engine isn't a good idea as this is hard on the lower end section the engine. Keeping it reved up to the torque limit rpm wise is the way you run a diesel engine anyways. There made to work and heat within reason doesen't hurt them either, as a matter of fact they run better and cleaner. Trans fluid mixed in at the approiate ammount keeps the enjectors cleaner too.
