I wonder if any one can tell me the correct mix of diesel and petrol I could
use in my 2 1/4 petrol engine?

A friend has very kindly given me 40 litres of 1/3 diesel 2/3 petrol
mixture. Colour blindness at the petrol station I'm told.

As I have an old car that 'will run on anything' I have to have the mixture.

Does anyone know if I can actually use this mixture?

It will probably run but the experience is likely to be less than
exhilarating.

I'd suggest diluting it 1:1 with pure petrol which will give you 1:5
diesel:petrol mix. That should be better.

Try a small volume test first in case you decide that a greater
proportion of petrol is needed.

Whatever ratio you end up with expect quite a bit of white smoke
especially when the engine is cold.

You're right though, it's too good an offer to ignore.

Keep an eye on the oil level as un burnt diesel will tend to run past the
rings and dilute the oil raising the level on the dip stick. Oil diesel mix
has a viscosity like water and is not a great lubricant. steve the grease


 
Thanks for the replies.

After doing a bit of googling it would appear that the best idea is not to
try.
So it looks like I have lots of cleaning and fire lighting mixture.

Assuming your proportions are accurate I think it would be better to
add this lot to 230 litres derv and use it in a diesel. The reason
being the mix will not burn well in the petrol, giving carboning up
problems and you risk pinking/knocking damaging the rings and lands.

OTOH diluted to below 10% the petrol will not harm diesel performance
or cause the injector pump problems.

Treat the mix as dangerous as neat petrol, so don't do this all at
once, add 5 litres of the mix into a diesel with at least 30 litres in
the tank already.

You're being over-cautious.

If your engine was one of these new-fangled things with catalysts,
injection and all the electronic wizardry, I might understand.

The Land Rover 2.25 is not in that category and will 'run' on almost
anything that has some petrol content.

If you keep the proportion of petrol high you will not have a problem.
Provided that you are not planning to indulge in a lot of cold running,
even the oil dilution potential that Steve mentions will not be an issue.

Now, where are the usual doom-mongers warning you about storing more
than a thimble-full of petrol?

I agree so I tried it :)

I have twin tanks so thought it would be OK
Mixed it down to 15% diesel and 85% petrol.

There is a bit of smoke and a bit of pinging when you pull but not too bad.
I will mix it again to get the diesel % even lower.

I have a long run to do next weekend so will burn it all off then.

Sister's BF ran a series III around the farm on TVO for quite a while, in
order to use up some which was lying around in a tank from when they had TVO
tractors, some considerable while ago.

Tractor Vapourising Oil, IIRC. slightly more potent than paraffin - we used
to reckon on mixing paraffin:petrol 5:1 to run in the old TVO tractors, when
we had some.

I think you have to time it to something like 6 degrees after TDC...

Yes, I think esso were the last to market it, since then the old
engine enthusiasts have dreamt up loads of recipes as replacements.
The thing is it was a one of those fractions that were condensed out
in the refinery so, like petrol or gas oil, it had a range of
hydrocarbons in it somewhere between kerosene and gasoline. Thus if
you make it by mixing lighter fractions, like gasoline, with heavier
fractions like kerosene, the mixture is different yet the vapour
pressure of the gasoline is still there, making it flammable like
petrol.

Which sort of points to how it derates an engine.

Thanks old man ;-)

It's the first time I've seen an acknowledgement that the mixture is
more hazardous than the individual components, I found out a different
way ;-)

I'd agree about the extra dilution. If you have an ex-military vehicle,
take advantage of the two fuel tanks, and keep pure petrol in one.
Start on that, get the engine warmed up, and switch over.

Ignition timing might need slight adjustment. Lower octane rating.

[waves hand]

It's likely illegal, but "illegal" doesn't correspond entirely to
"unsafe". I wouldn't classify as 20l jerrycan as unsafe, even though
the law sets a 10l limit on container size, and requires a screw cap.

10l for metal 5l for plastic but the cap just needs to be liquid and
vapour proof, so a jerry can with a proper rubber seal is fine. The
storage regulations are not simple, you can store up to 275l in one
place, without a licence, provided you meet certain conditions:
