There's a thread somewhere about about adding 2T to diesel to reduce smoke, but iirc less that a litre that's needed, I think it's 500ml per full tank.
I used to put in 250ml per half tank, it does work in reducing smoke.

Also almost all diesel is reduced sulphur, when doing that it reduces lubrication, now they've added replacement lubrication but it's still less than original.
In the states when this first happened they had engine failures as they hadn't replaced the lubricant, hence the first time people were adding 2T.

Does anyone add 2-Stroke oil in with their diesel.
Me and a mate were reminen reminas remembering back to when race tracks smelled of Castrol R. I then remembered a mate suggesting i add a litre of oil in with a tankfull of diesel, for some reason, and i wondered if tossing in some Castrol R would bring about THAT smell? Or kill the engine?

Also....

2 stroke oil is not cheap. Would it not be better to buy the better diesel....the supreme stuff...you know the stuff....the other pump no body uses.

I cant be bother to do the sums but an extra £10 of 2 stroke per tank doesn't seem like a good plan to me
 
In my view it is only of benefit to older engines, but I do think the TDI 200/300 engine runs better and is quieter with some TSO in the tank.
 
I've seen a kit to inject/dose LPG into a TD5... heard of it before, supposed to reduce engine temps - so ideal for tuned TD5's that are prone to overheating.

Tried 2 stroke in the TD5... didn't seem to do much... Millers additive seems to boost it a bit - first used this after a bad batch of Bio-diesel/diesel bug gummed my in tank fuel pump with black snot!

IMO, the "better" diesel is not "better" in the right way for the older mechanical FIP's - so I use TSO at 1%. I pay £2 per litre for it, so to treat a full tank, ( 80 l ) costs me £1.60 .... It isn't really an extra cost either, as the TSO gets burnt - the only "extra" is the 40p increase per single litre of TSO, which pro-rata is pretty much minimal.

That is the article I alluded to earlier on, thanks for posting it again, copied and saved hopefully not to get lost this time!

I found this bit interesting, parts in red even more interesting,

7. CONCLUSIONS
Based on the results of this study, the following conclusions are drawn:
• At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel lubricity.
• All diesel fuel sold in South Africa has to meet the SANS 342:2014 lubricity specification to ensure the proper protection of diesel fuel pumps and injector systems.
• The low sulfur diesel products sold by Sasol contain lubricity improver additives which are far more effective than 2-stroke oil.
• At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel cetane number.
• No measureable effect on all other regulated diesel properties was measured at a 200:1 dose of 2-stroke oil in diesel.
• 2-stroke oil can contain around 16ppm zinc, or higher depending on the formulation and batch.
• Trace amounts of zinc in diesel are known to rapidly accelerate injector nozzle deposits.
• Engine test results show that a 200:1 blend of 2-stroke oil in diesel results in a 2% loss of engine power in a 16 hour test due to injector fouling, a risk that would apply to any common rail diesel engine, but could also worsen fouling in older engines.
• Vehicles fitted with a diesel particulate filter (DPF) in the exhaust system could experience reduced DPF life due to the collection of ash and metal based contaminants in the filter over time with the continued use of 2-stroke oil.

So if you run a ****box and swear its okay then fine, but anything remotely modern avoid the two stroke oil.
 
Huh, i only wanted it to smell nice...
Like Castrol AaaaaaaaaaahhhhhhhhhR :D

Interesting article!
I have my doubts regarding the headline though. "Your 4X4 is not a lawnmower…" Given the amount of grass mine has come home with post 'playtime' sometimes, i'd have to suggest it could be, part time maybe..?

It used to be a substitute tractor for rolling and dragging chain harrows around a 3 acre paddock.

Another good article! Personally i doubt that current diesel is lacking in lubrication. Given the much higher tolerances in modern injection pumps and injectors plus the stupid fuel pressures involved, i'd suggest that if everything wasn't sufficiently 'slippery' inside, we'd see diesels seizing up left, right and centre!
