will synthetic motor oil or ATF burn in our diesels?

i have older 5 cyl dsl and ford 6.9
will syn burn in them?
I talked to one tranny shop, asked them for used atf they told me as they have more newer cars with syn atf.
has anyone tried?
one shop I am getting atf i am sure it has a mix of every kind of atf in it too, i dont see her fail to proceed, touch wood and thank you Lord.
Wish the good Lord will bless all of us driving with sticky side down and shiny side up.

YES

There is debate about how well..

You need to become educated as to the risk, before you do this.
The injection pump and injectors are the prime danger zone, if there is metal particulate, abrasive, or the big killer WATER...............

I carry gallons of virgin oil, and have used it as emergency fuel many times in 35+ years, WITH NO ISSUE...
My favored oil is Mobile1, never had any issue running as fuel even at 100% (at most a tiny increase of smoke).

Personally:
Here is a brief list of what I filter at one or two micron, run through a water separator, and run with no difficulty.
* USED ATF.
* Kerosene.
* 100+ year old lamp oil.
* 100 year old engine oil.
* 70 year old diesel.
* Castor oil.
* Virgin (food grade) vegetable oil (regardless of age) of more plant verities than I can recall or list.
* USED electrical transformer oil.
* USED mineral oil.
* USED Elevator hydraulic oil.
* USED Heavy equipment (crane, pan, bull dozer, etc) hydraulic oil.
* USED Industrial (manufacturing) hydraulic conveyor/handling oil.

Alternative fuel links (Diesel)

I have ran WMO from a variety of sources in my 300SD. It is unknown to me if it is synthetic or not. It did come from some sort of Diesel engine, though. I blend with 15-20% RUG and let it settle for a few days before filtering it down to 1 micron and adding it straight into the fuel tank. It runs well with a slight increase in smoke and coking. The adverse effects of running petro fuels seems to be much less than with running vegetable or animal fat based fuels. I have a 300SD that was run on WVO and I am very close to suspecting IP failure. If replacing the delivery valves does not solve my idle problem, I am going to swap the IP after re-checking the motor mounts.

I know people who have run fully synthetic oil in an OM617. I have not done it consciously, so I can't give first hand experience with it.

thanks
one shop I get used ATF every so often i am sure there would be syn atf in it.
My 300sd still run like a swiss watch.

curious will some amount of Kerosene run in a gas engine?

just wonder would small % of kerosene will run in a gas engine?
I have a 87 190e 2.6

gas engine has a much power compression ratio.

kero is a lot thinner than diesel or used veg oil.

TIA

There is less energy in kerosene = you burn more for equal power.

Yes, antique cars (before ww2) where built to run on lamp oil = kerosene / white gasoline.
Post ww2 vehicles where OK, but ping / spark knock could drive you nuts, and usually required changing the timing and Carburetor Ventura or jets.

In theory, a modern car could run kerosene BUT there would be performance issues and possible fuel system / engine / emission damage.......

With the higher cost of kerosene in most areas, this has no economic logic.

I was about to filter and burn off a bunch of used motor and clear tractor hydraulic oil that was going to go to the recyclers here and someone chided me saying how it was more or less against the law as it releases so many heavy metals into the atmosphere.

I argued that this is basically what they do when you take it to the recycling depot, it will probably get burned in some airport hangar or industrial shop heater, but he said it was always at a temperature high enough to completely burn off any of the harmful metals.(mercury etc...)

Is there anyone better informed than me on the subject?

I can't think of any heater that would burn hot enough to "decompose" metal into another element. If we could magically get rid of lead/mercury/etc. via heating then the world would be a cleaner place, and I'd eat much more tuna.

They're probably talking about incomplete combustion (aka lighting a puddle of it in your driveway) which tends to be nastier. Burning it hot and completely usually produces "cleaner" exhaust.

If you're worried about emissions on your car vs their heater, don't.

If you're worried about emissions on your car vs canning a burying it, eh maybe.

The used motor oil with high SAPs will eventually clog the dpf or cat (if you have one). ATF and other presurized fluid have some inhibitors that prevent them from burning or exploding under pressure, but they will still burn. Only issue is some will form some gum on the lines.

As said before they need to be filtered to remove the particulates and water. I used to get free used solvents. Those solvents were reagent grade and just the left-over in the bottle and not really used, so I didn't filter.

I am a bmw tech and change oil everyday. We use 5w-30 full synthetic in all our cars. I have unlimited access to this oil as I can easily catch it in my own used oil drum and filter it and so forth but I am wondering if this will be safe for my 300d.

It's full syn oil and wouldn't have any of the lubricating factors that my merc needs for thr IP??

I just bought my 300d and do not want to wear anything out like the IP??

What would you guys think about this using this oil as a fuel mixed with 20% gas??

That should be fine. Just make sure you blend with gasoline.

I worry more about how well you filter it to get out metal particles more than the lubrication from the oil. The 5W-30 full syn would have more lubricity than #2 ULSD.

I run my car on used motor oil / atf / gear oil all the time! I find that it just needs to be thinned down by either %10 gasoline or diesel. There is also a very noticeable increase of hp when using oil as it has a higher btu then diesel. also used motor oil has a lot of unburned hydrocarbons in it thus raising the btu even further.

I will do oil changes on customers cars and just pour it right in my fuel tank. 7.3L diesel ford has about 3 gallons of oil in it!

Don't even worry about the filtering oil if it comes out of well running equipment!
I usually filter it through a fine filter if the quality of the oil is unknown.

If there's water in it you will notice its milky, avoid it.

Thats all there is to it! excellent fuel source! easier to come by then veg oil

Mercedes used to allow a 10% mix of gasoline (up to m95 ROZ octane) in its fuel, in the days before winter-blend fuel, i/e/ 1955-1963, it's even in the early operator's manuals, which is where I first read it.

The issue of too great a level of gasoline is the lack of lubricity of the fuel, and the possibility of additive contaminants. For example, Mercedes strongly cautioned against mixing diesel fuel with premium fuel because at that time ROZ 98 gas contained vanadium as an additive. Apparently the vanadium reacted badly with the injectors and pump components. Regular gas didn't have the luxury gas additive, so it was ok.

If you can find out what the additives are in the oil you get, once filtered, you can confirm that the mix will not hurt your diesel.

Lab analysis these days is super cheap, it's all done by robots and computers, especially if you order a spectro-photometric analysis with all the pretty colors!
