Run used oil - Page 4 - Diesel Forum

I came on this thread a little late but Cummins has been offering this system even recently even on their fancy electronic engines that meters a little bit of the sump oil into the fuel supply to be burned all the time. That way you have no oil changes. Basically they turn the engine into an oil burner. Selling point is it saves fuel and oil changes.

im running 60% used trans oil in mine get it a work free saved 120 in the past 3 weeks it runs good off of it starts good too i filter it 3 times before it goes in to the tank and no oil from killed units only trans flushes it runs bettter off of dex3 but the sp is really stinky going to do it for a while

I've got 50 gals of clean used oil waiting for me, just need time to get it and put together a filter system. We'll see how it works. Having a hard time getting waste veg. oil around here, everyone is getting paid for it.

ok up date.. its been a while. I have stopped making BIO , just because I don't have the time, but I had about 30 gal of left over WVO and I started dumping my waste motor oil in the drum and when it got full, I filtered it through a toilet paper oil filter into the next drum, then filtered it through a screw on fuel filter rated @ 5-8 microns , then put it in my back tank mixed with diesel at about 30-40 % mix....ever time my main tank got low the trucks tank computer would just refill the main tank till it was all gone. I ran about 50 gal through the truck in February and march ( not that cold I am in south AZ ) , my truck ran fine , no smoking , no hard starts. matter of fact the truck ran great.

There have been thousands of diesels burnind millions of gallons of waste motor oil for many, many years. If filtered right, no problems,I run 25% to 35% mixture in my 94 IDI , not a problem. Maybe in newer engines more reserch is needed, I dont know. Also, as far as the people claiming the bad efects on the environment, you can buy waste oil burners for your home and shop that are EPA approved. Many buisneses burn waste oil, at open nozzel pressure, in oil burners. The internal combustion diesel engine also adds compression to the mix. I for one dont see an issue with it. Tim

smitty--and the pressure at the nozzle in the waste oil furnaces is a whole lot less than in our idi's!!!!!!!!!--so i wonder which will burn cleaner??????? [img]/ubbthreads/images/graemlins/biggrin.gif[/img] [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

I have a clean burn brand waste oil furnace in my shop.
I got it used, I think it's a late '80's unit.
It was a bit finicky to get running at first, but once I learned a bit about it's operation and changed a few parts, it's been a great heat source.
I use an old basement fuel oil tank which I fill with used oil atf etc, (no gasoline or paint thinner /etc)

The ignition source is literally an arcing spark across two electrodes about a 1/4" apart, the injector nozzle sprays the pre heated oil into that spark and you get your "torch" flame. The flame is contained inside a basic steel drum heat exchanger which has a big fan next to it.

This unit is old an I'm sure could use a minor overhaul - I can still tune it by adjusting oil and compressed air pressure so that the exhaust coming out my chimney is totally clear and has only the faintest smell of combustion - much cleaner than a wood burner - no smoke and no ash at all.

I can heat my 1500 square foot 12ft tall walled partially insulated pole building from 20F to 70F in about 20 minutes with this 185k btu (max) unit.

I would recomend one of these to anyone that spends time in their shop in the winter. Start telling friends and neighbors you'll take their old oil, they'll be happy to drop it off to you - right now I have more than I need and I'm still collecting for winter!

Here is my experience with used motor oil. 1st time I ever used any I mixed 1 oil change in 25 gal of my 50/50 WVO/diesel mix. About 1/2 of it then went thru a 5 micron water filter into the truck, and the tank was topped off with dino diesel. 1/2 tank later I have 2 junk injectors. Truck has 85,000 on it and I had been running WVO and diesel mixed for quite some time with NO troubles. 1ST time I threw motor oil into the mix I am buying new injectors.

USED MOTOR OIL = EXTREAMLY BAD INDEA IN MY OPENION AFTER THIS EXPERIENCE

VD350 · 07-26-2007, 10:31 AM

mark what is your truck?

I ran probably 30 gal through my tanks this summer with no problems

Hi. Been a while since I have been on this board.

I will give you my experience (2001 F350).

I have only run UMO (and ATF) with bio. I mixed ~10-15%. (Well settled UMO - I think settling helps a lot). When mixed (straight) it made the bio very dark and dirty. Ran great though, no problems, maybe a little better mileage. Could smell it some.

I also added the oil to the WVO before brewing bio a couple times. The resultant bio much MUCH clearer (although still somewhat darker, you could easily see through a fair amount of it). So (for whatever reason) i think that brewing it with the bio cleaned the UMO up quite a bit. In any case, I did think the bio was a little tougher to wash.

So one time I am driving down the road, and I notice some smoke (a little more than normal), then it got worse, etc. I topped off with diesel, and put some BK 44 (whatever that good stuff for the diesels is anyway). No improvement, and the truck keeps smokeing, gets noisier (almost like it was "nailing" or something. I think (%$^&*), and start "shopping" for new injectors, etc. I keep driving it (a couple/few tanks of diesel. Then the truck starts to "clear up" (smoke/noise, etc.) Then it runs as good as before.

Then I came to the conclusion that that I had used synthetic oil (Rotella from my last oil change etc.). The other stuff I had been builing up for (years...LOL) of non-synth stuff. I used that first because it was well settled.

Well, I used up all my (no snthetic), and I like to run synthtic in the truck and certainly in a VW TDI I pickedup /put together also).

So I have had to further experience except a year and a couple months (about 20K) later, my truck still runs great (bio when temperate, otherwise diesel).

Me personally,, if I used non-synthetic, I would use it up as fuel in my truck). But I would not "seek out UMO". Although I have heard the UMO can lower the gell point of bio significantly.

One lesson for sure: If you do get "ballsy" and try some UMO, DO NOT use synthetic.

A funny postscrip. I friend of mine who had a shop for a while had a UMO heater laughed when he heard this. He said, "I thought everyone knew synthetic motor oil does not burn". (He apparelty got some in his heater and had a time of it....LOL

Sounds like mine, except the fact that the oil I ran was NOT synthetic. It is starting to clear up a bit. I am not driveing it any more than I absolutly have to. Have some of Beans split shot stage 2 injectors ordered. Hope to get them this week, and install them Sat.

In blends of 5 to 15% synthetic Oils and Trans fluid burn just as well as petroleum based oils in my experience

skunk · 08-11-2007, 05:44 PM

my sig says about my truck. it burns a bit of oil. i may need a ring job or something. burns like a quart a week or so. i drive about 50 miles a day. so if he wants to put some UMO in his tank who cares? i put UMO in my heated WVO tank all the time...

marksuttonjr · 08-11-2007, 09:18 PM

I'm not trying to dis anybody for running UMO. I just stated my experience with it. I guess that I should also meantion the fact that I am seeing this girl with an extreamlt jealous EX. 1 night when I was at her house my truck went from 1/2 tank to full while I was inside. It had a gasoline smell when I drained the tank the next day, but who knows what else was added. That was the tank of fuel before the UMO went in, so maybe my BAD experience had nothing to do with my actual usage of UMO.
