Black deisel

Right that link did not work to well so click the link and put black deisel in the box at the bottom and it comes up, sorry I'm a bit of a dimwit when it comes to the black art of computers.

Anyone tried black deisel, seems like it might be a good way of re-using old engine oil

Sorry chaps but running the M51 diesel engine on this will eventually kill it, take it from me as a marine diesel engineer that possibly anything upto 12 month later if used regulary it will cause problems... ive seen engines throw the towl in after a day on this sort of mixture (the fuel pump just cant take it and the electronic injector has difficulty registering it) if how ever you had a 200 or 300 tdi (disco or 90) it would be happy to run on the stuff, :eek::D
 
It's no good full stop

Carbon will form on injector tips causing white smoking and ruff running until cleaned off.

Burning lubricating oils causes excessive deposits in the cylinders causing piston ring and bore wear.

The burnt additives in the lub oil are abrasive.

And if PC Plod dips the tank and find it you'll loose your car to the nice people a Customs and Excise who will then fine you.

At my boat yard ive got a 200tdi stans alone engine with a 4kva geny alternator bolted to the back, it keeps cool by pumping water out of the canal threw a rad then a calorifier then out, (geny for elec at yard and calorifrier for hot water in workshop) its been running for nearly 2,700 hrs (fitted hour meter to it) at a steady 3,100 rpm (to spin the geny alty fast enuf to phase in the 240v with out spikes or surges) and its running on the **** oil from services we do to boat engines, all i do is filter it, add 20 percent red diesel then fire it in the engine... fair enuf its a tad smokey but dont forget its under a massive load from the alty generator... still running fine, il post a pic of it in action on monday.:D:D:D
 
That poor engine, it will be dying a slow grinding death :doh:


When it starts breathing real bad and is using lots of oil pull it apart and post pictures of the damage. :D

personally i wouldnt chance it. i removed a fuel injector pump from a M51 lump last week and christ i wouldnt fancy replacing one if i mine broke. i sold it on ebay for £255 USED!! mechanics bills on top of that would be mental..
 
Ok just wondered as some of the Pajero guys have been using it with no side effects and they claim smoother running, surely if filtered correctly it should not cause excessive wear and can't see what its got to do with customs and excise as its not red deisel. Tbh I'm not going to try it, just my curiosity, I,ve been in Engineering all my working life and used to be on the boats servicing and maintaining cats, callesen, gardner and volvo's and had never heard of black deisel before. Sheltered upbringing ha ha.

I think the customs and excise thing is that you can't run any fuel on the road that hasn't had the duty paid.
Red Diesel is just one example of duty-not-paid fuel.

Not sure if homebrew biodiesel has some explicit legal exception to this?
 
How much black oil have you all got I wonder? If like Mike you`ve lots and don`t want bills for disposal and can burn it in a static engine, ok I can see sense in it , but saving a coupla quid by messing about filtering some solids out, (But leaving liquid acids & contaminants in), and risking damage to expensive FIPs is not wise.

Think i read somewhere you can use 2,500 litres of biodiesel a year without paying tax.
 
black oil is bad full stop..kills the engine and evades tax AND really pollutes..

thats not to say the engine wont run on it..crude diesels will run on just about anything..

if you after saving cash,then as you seem not to care about evading tax then you might as well run red,atleast its good for engine...bio up to 2500l (if you make it) is tax free..but be warned must be well made or that too will rot your engine..(injection pump seals fall to bits etc..)

how do i know?? i am diesel mechanic on everything from transits to 12l v8 scania's plus all plant machinery...seen alot,tried alot... (of different fuels)..and **** fuel is the main killer of injectors pumps etc...not economically viable in the end..ie costs more to fix than savings made...

Wise man.
Just to address the main problem with using large amounts of lube oil in your fuel tank apart from carbon deposits building up on the injector tip coursing poor running is that the additives in the oil when burnt produce lots of ash.
This white ash is abrasive and will slowly grind the rings and bores away causing loss of compression.

Well personally I have never heard of black diesel! All very educational. However sound like a really bad idea. Parts of oils job is to remove acids and other corrosive elements that form during the combustion process and thats half the reason we have to change it once in a while! So to go and put that corrosive and abrasive stuff BACK IN to the engine defies all common sense. Sure, you might be able to filter out the abbrasive particles down to a certain size but you will still have all the harmfull chemicals present. Stoopid idea and if you do it then you deserve all the engine damage you will probably get!!!!:)
 
At a garage where I used to do a lot of software support, they had a pressure jet heating boiler that was "specifically designed" to run on waste engine oil of which they had plenty. It rarely managed to run for more than a week or two without failing and produced more smoke than the liner Canberra on full chat.
