low ash 2 stroke oil additive?

[Falcoron]

Anyone dose their diesel with low ash 2 stroke oil?
I remember reading in a car forum that a small dose is really good for diesel engines, is that true or of no value at all?

 

[The Q]

It came originally from the USA where the first edition of low Sulphur fuel in California was a cockup, as it removed some of the lubrication from diesel fuel.. Causing some fuel pump failures...

The redesigned fuels in modern cars don't actually need it but...
Side effects were noticed in that adding 2SO reduces smoke from older engines and less noise.. Certainly on my old landrover (38 years old) it does just that..

So yes I put in around 200ml for a 45ltr half tank refill..

Maybe an idea for old engines but I don't think I would do it on anything modern, particularly common rail.

Why add 2 stroke oil when you can buy fuel additives that are designed and marketed specifically to be put into diesel ?

 

[Falcoron]

I'm not saying you should, it was mentioned in other forums and was touted as being good for diesel engines.
Same reasons as post 2.
Maybe good for the old smokers!

Guy at work used to put cooking oil in his old Citroen van as it was cheaper than diesel, ran it for years although it was an old smoker.
I don’t think it’s worth risking anything in an expensive engine that was not meant to be there

Early diesels should run on any sort of oil really, not the modern ones though! Was the original diesel not intended to run on coal dust?

Interesting, thanks.

I ran a MG-ZT ( BMW 2.0 engine) on heating oil with a ltr of gear oil per 25lts as a lubricant for years. no issues whatsoever.
Wouldn't risk on a boat engine though as the costs would be horrific if it went pete tong!

Mmm. I added a litre of engine oil to 50 litres diesel in my Disco 3 to lubricate the pump after draining my tank because I had mistakenly put petrol in. 50 miles later the crank broke and the resultant catastrophe on the motorway can only be described as a tin of old bolts been shaken violently. It is possible the injectors had been damaged but I don't think that would cause the crank to break. I suspect the addition of oil may have had an affect on combustion timing causing pre detonation that destroyed the crank. I would be very hesitant adding anything to a modern engine.

Because the additives are vastly more expensive than 2SO.
In the summer I also use cooking oil if I can get it cheap enough, only a 50/ 50 mix to diesel though... when it's cold weather, Cooking oil is too thick for most engines / fuel pumps. So soon as the weather cools that's it till next April



1 Litre 2SO to 50 litres diesel yep way to much around 5 X to much..

Are fuel additives really that expensive ?
eg £12 to treat 1000 litres

I wouldn't use cooking oil as fuel for the diesel engine on a boat .

Mmm. Maybe it was on its way out anyway, i ran this engine like this for 4 years and i sold to a mate who tows a caravan with it now and with 220k miles its running like a watch.
The reason i did it in the first place was a friend had been running his Defender on it for years previously. Only thing he ever replaced in over 150k miles was a fuel pump. Think he still has it but haven't seen him in a long time.

but no way would i do this on a boat.

I use Millers diesel treatment/injection cleaner now on my wife's Honda CRV only because it came with it when i bought it so why not?

Tcw3 2 stroke occasionally dosed in the tank can be good for older engines that have fuel pumps purely lubricated by the diesel running through them. Modern diesel can sometimes lack the lubricarion qualities it once had. Tcw3 also has many other great properties in it too.
