Can I Burn Crude Oil

I have a source for it but if I filtered crude oil and mixed it with some gas or diesel , could it harm my Ldt-465-1d?

I think the short answer to your question is "yes".
I'm not sure it would even light in a small compression ignition engine. It is after all pretty... well, crude.
The SP's early steam engines ran on bunker C oil and it had to be steam-heated just to get it to flow; that stuff was at least a few steps up the refining process ladder from crude
Might mix up a batch and send it out to a lab to see what the cetane rating works out to, as well as having a flash test done to see if it's flammable. A few crudes have the flow characteristics of cold peanut butter so getting it through injector pump, lines and injectors might be close to impossible.

Only Grandpappy Amos of the real McCoy's could burn bubbling crude... ACE

Is it true crude oil or is it "drip gas"? Growing up in WV a lot of the good ol' boys would get free drip gas from the separator tanks on the natural gas wells. Drip is kind of a natural gasoline and has a distinctive odor to it due to the impurities. You could always tell who was running it in their old truck or tractor because of that - don't think I would try it in a modern fuel injected engine

Your multifuel might burn drip ok but like the other posters I am not sure about crude. We had a boiler at my work that burned #6 oil and without steam heat it handled about like crude...think molasses.

You can boil a pot of crude and let it cool. The clear film left on top will be kerosene. This is how they got lamp oil/kerosene a hundred years ago. This crap is pretty dirty though. I'd burn it in a emergency but not for everyday use. I've mixed drip gas with used motor oil with good results. I read in a TM or some where they could handle up to 71%crude?
But i can't rember where. I wouldn't try it, there is just too much trash in it waiting to kill a IP. But the engine would have to be preheated to start. Heavy fuel oil is mostly used motor oil. The ships go out to use it for fuel. That's where your used oil goes when you "recycle" it. Free fuel for some body else! It's mixed in with other byproducts from refinerys and goes up in smoke. I burn UMO alot. It has really cut the fuel costs!

The crude I can get is thiner than motor oil. I know about drip but i rather use crude. I the tulsa area the crude is pretty thin . This flows Easy.

If you can find out the API viscosity you want it fairly thin, and filter it. It should be ok but I would worry mostly about clogging the filters or lines and negating any savings. You can probably find an oil analysis for a nearby field. If it is actually condensate be aware that is more volatile than gas. They used it in cars till about 1910 but kept blowing up the tank cars hauling it.

One source for Cheap fuels is at Marinas, Gas left in boats is not good to GO!! I used old gas from a truck I bought from GL, it runs good in the Deuce!! I remember a Phrase from a Driver Inst. in the USMC when I went through Motor Trans School."If you went out and drank alot of Booz the night BEFORE,You can PEE in the tank of a Multifuel and it would RUN!!So that covers a lot of STUFF!! Instead of Off Road diesel at the pumps, I have Heating oil delivered to my home.Store it in 55gals if U must! How legal , or not legal, is Offroad Diesel in a Deuce? It IS an Offroad vehicle,it calls for Multifuels,so how would that holtd up in COURT?I don't even know what color the fuel is in my Deuce? It must be pretty Black!! I just put Drain oil from Farm Tracter in it today!Happy Fueling!!

Using off road diesel in any vehicle that is driven on road at all is extremely illegal and carries big fines.

There are not many questions about the Multifuel that you can ask that Uncle Sugar (or Continental) hasn't already asked. And this is one that has already been asked, back in 1978.
