I have read a few threads that putting 2stroke oil in diesel cars is good for them anyone tried it ?

New one to me can't say I would want to do that!

Here we go again, try it.

I'm wanting to know if it actually is good and does help I'm quite skeptic as well

I've done it quite a bit. Presently running without it. 

 

Cant make my mind up if it helps - but It's said to make the engine lees smokey and sound 'smoother' when cold.

 

It's a bit too much of a hassle when fueling up too.

Hasn't done any harm though has it an what two stroke did you use an is. Your vrs belt or asz an what mileage thanks ash

This has been covered many times, so I'll summarise for those incapable of using google / search facilities:

 

Modern diesel has no sulphur in it, unlike old diesel.  Sulphur acts as a lubricant, especially useful for the fuel pumps.

 

The theory is, that by adding 2 stroke oil, this helps lube the fuel pump, acting as a replacement of the sulphur.

 

Yes, I've tried it, no, I'm not still using it.  I figure a fuel pump replacement is probably cheaper & easier than faffing with 2 stroke at every fill up.

This 'lubrication' refers to old tech diesel pumps, modern common rail and PD engines don't have old tech diesel pumps.

 

It's a myth based on old information which is no longer relevant. I doubt it would do any harm although synthetic two-stroke oil is expensive and the molecules are a lot larger so it might affect the atomisation pattern or possibly even partially clog the injector head over time so on balance, since there are no benefits I wouldn't bother.

 Put Acetone in as well to counteract the larger molecules - and you are back were you started - with possibly no gains.

I've tried it on my PD100,  tried different brands and recommended ones from what I read on forums -

 

 

Result - NOTHING WHATSOEVER.

 

total 100% waste of time.

 

 

NO percievable gains at all,    same MPG,  same noise,  same rough ass diesel feeling.

 

 

Another one of those bull**** things,   another bull**** one is the 'cage mod'.   

and to think I thought I was mental for thinking door colours dont match...

If you want to mix fuel with two stroke oil, get a 50cc bike mate... dont go putting it in a car. just my two penneth worth.

Don't do it!!!

 

Re-read your question. You are not thinking of doing it, just asking if its a good idea. In my opinion, its a terrible idea.

I thought I noticed reduce engine braking in higher gears when I tried using it but I suppose it could have just been a placebo

Used it for years. Just sploshed some in now and again. Doesn't make any difference I can tell, but now have 184K and no problems (touches wooden head !). Originally started using it when read report of Mercedes using it in Russia - but this was years ago and rural Russian fuel was very suspect so doubt they would do it now. Tried checking fuel consumption very carefully for a while; came to conclusion that there were more mpg per diesel fill up - but the extra was exactly the same as if the quantity of 2 stroke had been diesel! Clean fuel and air filter much more important.

 

BTW the cage mod did make a noticeable difference to me; it solved a stumbling problem with a cold engine.  It will only "work" if there is a problem with the connectors, so no problem= no improvement. Several manufacturers use it in connectors to MAFs and computers, although I think it is more about preventing corrosion.. Again, it can't do any harm.
