Garages often do this as paraffin is cheaper than diesel, so they mix it together in the diesel tank. It buggers up the motor in the long run, you lose power big time and your fuel consumption goes for a loop. Should you feel that there is paraffin in your diesel then best is to add a bottle of marine two stroke oil to the mixture to add back viscosity and burn ability.

You will only feel the difference once the injectors wear out due to lack of lubrication, when in doubt add some lubricant to your tank.
I have seen a Isuzu that runs on parrafin and two stroke for a large part of its life without any problems.

search 2 stroke oil. But you need to be really bored to read it.

qualities, hence the need to add 2so. They, however, ignore the fact
that this phenomenon happened when the refineries first started
reducing the sulphur content of diesel, in the late nineties (and only
in overseas markets), and that by the time SA started doing it the
experts knew about the problem and added lubricant additives to combat
this problem.
There must be 100+ pages on this on the 4x4 community website - for
your own sanity don't go anywhere near it.

Cars are DESIGNED for 50PPM - and have been for quite some time!

>> a sample of the 50ppm diesel he took from his tank was found to be closer to 400ppm
How many people actually look at the pump to see if it is 50 or 500? Not many. They don’t even know the difference.
And adding 2stroke oil is not going to make it cleaner, nor fix the 400ppm problem!

distance's extra filter's, and so on. If your 4x4 is as old as mine,
don't worry too much. Most 4x4's prior 1999, as I have experience are
kick ass tough.
My 2c worth, sorry 5c nowadays :)

department from BP SA, after I complained about filling up my 4x4 with
diesel that was contaminated with paraffin.
Filled up at the BP garage on the Trans Kalahari Highway, as you enter
Namibia en route to Gobabis a few years ago.

I don’t think there will ever be consensus about the benefit (real or not) of adding 2 stroke oil to diesel.
What I would be more interested in is to know if there are any negative aspects to adding 2 stroke oil to every tank of diesel other than you might be wasting your money?

I’d like to see lubricity values from an actual testing centre.

There is a study floating on the Interwebs on the various additives and the improvement in lubricity, if I find it I'll post the link.
Nico Roets
Me too. Especially the diesel from the pumps.

Doubt if you will find a study like that in public domain. Unfortunately. Not sure if there is a lubricity standard for diesel yet.

I use approximately 500ml of 2-stroke oil in every tank of diesel (300tdi). I almost always fill up at my local Sasol filling station and usually put in at least 100l to 110l at a time.
Perhaps it’s only my imagination, but my perception is that the truck smokes less when using the 2-stroke.
Not very scientific, but I reckon it may help, and it very unlikely to cause any harm, so why not?

relates to older engines with a mechanical diesel pump. The argument,
as I understand it, goes along these lines:
1. The pump and injectors are lubricated by the fuel. This is not the
case with modern common rail engines.
2. The sulphur in diesel available at the time when these engines were
being built contained 500-3000ppm sulphur as an impurity which
improved the lubricity of the fuel. As a result, lubricity additives
weren't that important and no lubricity standard was legislated.
3. Modern common rail motors don't like lots of sulphur in the diesel
and are supposed to run on 50ppm diesel, as well as not needing as
much lubricity in the fuel as older engines.
As a result, a lubricity additive is a good idea if you run your older
design engine on modern low-sulphur diesel. 2so provides this extra
lubricity.
Have I understood the argument correctly?

>> the petrol jockies are not surprised when I get out the two stroke, so many have to be adding it!

light aircraft runs on pure jet fuel (JP1 / Avtur / glorified power
parafin). And they are reaching for the same life between major
rebuilds as the Avgas engines (about 2000 hours). Injection systems
are the same as modern car systems, main addition is the FADEC control
systems.
And further, in Botswana storage life expired JP1 are just blended
back into the normal diesel supply. Don't know about SA, but I suspect
it could happen here as well.

There is a turd ( water, dust) in the diesel :-)

That, I find surprising! ;-)

" I wish I could discuss this with a properly qualified scientist who has actually done some research on this issue. "
The properly qualified people are employed by the fuel companies. I think that says it all (for modern engines).
Older engines are designed for the type of fuel available when they were released (28000ppm up to ±2000, and 500ppm until a few years ago).
Also to build on (one of) Eric's comments, New Technology diesel engines could not be imported into SA for quite a few years until the Sulphur content in our fuels was decreased.
However, this drive is not in the interest of more efficiency, but to meet Euro pollution requirements.
Finally, re putting 500 into my Isuzu (they suggest 50ppm), a technical friend at VW, who I questioned stated that 500 might clog the oxygen-sensor (lambda) in the exhaust, but that would be about the limit of damage it would do (use that, don’t use that). I notice that Amaroks are not too fussy in this regard. He did not speculate on the need for more frequent oil changes, like used to be the norm when our Diesel had 28000ppm). FYI these were because the combusting Sulphur made H2SO4 which landed in the oil, and could only be neutralised for a safe 5000km or so.
Finally, this thread is re Paraffin. Using this will give lubricity problems, which can damage your engine, so if you get crooked with a tankful of mix, it makes sense to put that lubricity back. (I guess 2so would work??). I would not use other fuels in the long-term –in fact my Ranger 2500 handbook (horrible dealer support) said that biodiesel must NEVER be used.

Subject: Re: [Overland] Re: Parafin in a diesel engine
The problem with this discussion on the issue of fuel quality, lubricity values and the benefits of additives or not is that it is being discussed by a bunch of people (on this forum and others) who are not experts on the subject but who are convinced that they are right in what they say and say it with the utmost conviction.

When I was still in school my dad drove a 1981 Merc 300D. In the owners manual it stated that for winter use, to avoid gelling of the diesel, you can add up to 10% kerosene (which I think is the same as paraffin?) with the diesel. I'm assuming if its in the manual it could be done without detriment to the engine.
This always makes me wonder how much paraffin is necessary to start causing damage. Perhaps, with today's diesel, a smaller percentage paraffin can cause damage than the 10% in 1980's diesel, but surely the odd bit of paraffin in diesel won't kill the engine too quickly?
