will synthetic motor oil or ATF burn in our diesels? - Page 2 - PeachParts Mercedes-Benz Forum

I have run a mix of syntheic Motorcycle oil.I keep 90 gals,in case of war,or the grid fails do to solar flare.

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)

.

Even though my OM606 is still a IDI diesel, I can't imagine that pushing the creativity of fuel this far in a remotely modern engine works? Is this only for the early cars (300 SDL, etc), or would my OM606 burn a mix of properly filtered oils, if cut with say, Kerosene?

Properly filtered, and properly heated/thinned/etc. it will burn just fine in a 606. The 606 still have mechanical plungers(just computer controlled), mechanical injectors, and good old fashioned pistons.

The pump *may* be more prone to jamming up with poor fuel-it's a bit more refined than say a 616 pump.

Interesting. I've run quite a bit of JET-A through my 606, and it's just fine burning that when mixed with regular #2 diesel.

This has got me started thinking where it'd leave you if you ran something like 50% centrifuged/ filtered/ water separated used motor oil/ ATF/ hydraulic oil/ etc with 50% JET (essentially #1 kerosene).....

I have an 82 300D and I run straight Jet-A in mine. Every so often I will throw some used turbine engine oil in it thinking it will help lubricate things a little bit. Had read that straight jet would be fine for 300D wouldn't be a problem. Any thoughts or was I misinformed. Sorry didn't mean to change subject from syn but thought good thread to ask on.

If you run jetA a.k.a. kerosene, you should include at least a few percent of lubricity additive for piston engines because the fuel feed pump, IP and valves need lubrication whereas a turbine fuel system doesn't. The very best lubricity additive is biodiesel.

The very best winterizing additive for biodiesel is 'stale' jetB or jetA plus about 10% petrol. My 88 Toyota diesel truck runs a mix of canola B20 plus jetB and pump grade ULSD through the winter to temperatures below zero without problems.

Is there anyone better informed than me on the subject?

It is possible to "burn off" complex compounds in an engine's combustion chamber and break them into smaller compounds, which are them burned as fuel. But you do this when the temperature is high enough to burn without massive amounts of smoke (i.e. the stuff that didn't get broken and burned).

If your diesel fuel mix is such that plumes of black smoke are following you everywhere you go, then your mix is not being burned (logical). Dilute it and add about a cup ful of turpentine per 10 gallons, which increases the cetane rating of the mix (a trick I learned from old truckers).

There is no way to separate any element into its subcomponents without creating a nuclear explosion.

Why do you think they called it "atomic" and "nuclear?" They were describing the rupture of the bonds that keep elements together.

Exactly. I try to keep about 5% biodiesel in my mix for this reason. Not enough to worry about the seals that I haven't replaced, but I like the added lubricity.

This has got me thinking about adding maybe 30%-50% WMO to my jet fuel as maybe being a decent mix to burn in this thing.....

when Safeway changes the oil on there highway tractors they just bump all the oil from the crankcase into the fuel tank, and go.

I have access to a 55 gallon drum of Varsol being disposed of. Anyone know its combustion properties? Is it mixable with diesel at least? I have a 2 tank vegetable oil system, so I can keep it separate if needed...
