It's easily possible.
Taken straight from the Lister CS instruction manual: Kerosene may be used
but only if an admixture of 1/2 pint of lubricating oil per two gallons of
kerosene is used.
Use about 1 pint of cheap 20/50 lub oil with about 5 gallons of 28 second
kero and the old Peugeot Diesel engines will do 200,000 miles without any
problem. (so a friend tells me :-) )
Lister must have done their research and experimentation and I would trust
them 100%. How do you get 1/2 pint to two gallons seriously wrong unless
you're a nincompoop! There is obviously a fair tolerance in their suggested
ratio, if it was critical then Lister would have brought it to the user's
Quite easily actually, remember that the resultant 'mix' is reliant on
how well the two elements are combined - a bit like 2 stroke fuel,
always best to add the larger quantity to the smaller that has been
dispensed into a suitable tank/can.
There is obviously a fair tolerance in their suggested
With all due respects to Lister, they will have designed their engines
to run on 'crap', unfortunately some other engines will not and this
being Usenet and all that one really shouldn't just assume that the OP
is talking about portable/stationary engines just because the groups
name is uk.rec.engines.stationary...
Actually quite a compliment to Lister I think! I'm sure that no one (even on
usenet) would be daft enough to assume that
the instruction book for a vintage slow speed engine hewn from solid iron
'would do' for a modern whizzy HDi lump or similar ;-)
Yup, and I've never had trouble mixing 2-stroke either, even at the age of
16 when 2-stroke oil dispensers lived on garage forecourts. I re-affirm that
anyone who can't mix up a bit of oil and kero at roughly the right ratio and
stick it in a fuel tank is a nincompoop - and most likely wouldn't be asking
the question in the first place.
Nonsense, Lister provide a list of specifications for fuel oil for their
engine, their specs meet BS 209 (1937, high speed Diesel fuel) It
specifically mentions that 'crap' (as you put it) like residual oils must
not be used.
The question was 'can a diesel engine run on kero and what would you add to
it.' the answer is yes, and lubricating oil. The OP didn't want a thesis on
differing fuel injection technology and the universal suitability for types
to handle kero.
Being Usenet it would be less condescending to assume that the OP was
referring to SEs on a SE group unless he specifically mentioned that he was
Err, no, these people are the ones most likely to ask such a question.
Also, lets just remind ourselves as to what you actually said shall we
"Taken straight from the Lister CS instruction manual: Kerosene may be
used but only if an admixture of 1/2 pint of lubricating oil per two
gallons of kerosene is used.", so if someone does as you suggests and
fills a two gallon tank all but full of Kerosene, then adds 1/2 pint
of 20/50 on top and then starts the engine are you seriously
suggesting that the injector pump will receive the correct
lubrication - if so you are IMO, and to use your phrase, a nincompoop
I was talking about diesel fuel oils, which as you should know can be
inconsistent around the world, but if you want to purposely
miss-understand my point to carry on arguing so be...
Then the ONLY answer should have been "NO!". Unless we know exactly
what engine the OP wants to use this Kerosene/oil mix on the question
can't be answered unless the basics of the differing fuel injection
technology are mentioned.
Sorry but you seem to understand even less about Usenet that you do
fuel injection technology, I also post to a group that was set up to
deal with (home) video content creation - you would be surprised to
know that about half the posts are now about digital TV (simply due to
the fact that the word "digital" is used in the groups name), how do
we know that the OP hasn't simply asked this question here because of
the word "engine" in the groups name?...
The original question was "Is it possible to run a diesel engine on
kerosene?" which is equivalent to a 'would it be OK' question, so
indeed the answer does need qualifying, which is what was (originally)
done. My comment (above) was in reply to the suggestion that there was
no need to go into such details, a simple - "Yes" - answer being all
that was required. May I suggest that you put your dictionary down and
try following the discussion before jumping in with both feet...
Not in my book it isn't. 'Possible' and 'sensible' are two totally
The OP's first version of the question was exactly
"Can you run a diesel engine on kerosene? If so what would need to be
Are you seriously suggesting that you would answer 'Yes' to the
following, "Is it possible to run a diesel engine on petrol?", after
all it's quite possible for a diesel engine to run on petrol  and
as the 'OP' had not said why they might want to do so (or indeed if
the question is just hypothetical) - should we just assume that they
want to 'kill' their engine?!
 for a very short period of time before something breaks big-time
No, I wouldn't because petrol has never been regarded as a suitable
fuel for diesel engines (apart from a few multifuel engines).
In fact I think you might have trouble starting a diesel on pure
A quote from a Gardner engine instruction manual (4LK)
"Paraffin, as used in lamps and heating appliances, is an excellent
fuel, having a high ignition quality, and, therefore, particularly
suitable under conditions of extreme cold, but , if blended for use in
spark ignition engines, is unsuitable for compression ignition
engines, since it has a low ignition quality"
Not sure which one.
Don't answer that <G>
BTW my VW diesel car ran perfectly well, albeit driven gently, on 50%
petrol/diesel mix for a little while, after some (ahem!) careless
refuelling. Starting was noticeably poorer, though. I filled it often
(with diesel!) to dilute the petrol for a couple of weeks, as well as
adding a bit of 2-stroke oil to the tank, then ran the tank right down
to get rid of as much residual petrol as possible.
That was about 60,000 miles ago, it now has about 160,000 on the
I suspect that modern computer-controlled diesels might cope better
with that sort of insult than would the older, purely mechanical,
models. Just guessing there.
Good point. I was given ten gallons of Diesel/petrol mix & disposed of it by
adding about three gallons per tankfull to my 20 year old BMW 535iSE with a
3.5 litre straight six petrol engine. The difference - if there was one -
was minimal & the only thing I noticed was a faint Diesel smell for a week
