This replaces the lubricants (sulphor) that used to be in Diesel but is removed in modern diesel to reduce smoke/ pollution
Recently designed diesel- engined cars are tested to work with the modern low-sulphor diesel and are fine without additional lubricants (as above, the veg-oil acts as a lubricant)
Earlier common-rail diesel engines (roughly 1998-2007) may have problems with low - sulphor diesel, the (pre) added veg-oil may be enough to lubricate the pump/ injectors but these components were not designed for this fuel
A little low- ash 2-stroke oil may help to prevent wear on these components, and there have been reports of engines running smoother & quieter
You must be careful, though, 2-stroke oil was designed for 2- stroke petrol engines, not 4-stroke diesel engines, some 2- stoke oil may react with diesel or the veg-oil (bio-diesel) added to modern diesel there are
There are 3 basic types of 2 stroke oil -
Semi - synthetic
These cannot be mixed, if you are running a 2-stroke petol engine on Castor based 2- stroke oil and wish to switch to synthetic, you must strip the engine down, clean off all the old (castor based 2-stroke) oil/ wash it out with petrol, rebuild the engine using the new (2-stroke synthetic) oil, and run it with the synthetic oil - you cannot use Castor- based 2- stroke again without going through the same procedure - mixing 2 types of oil may cause a reaction, producing a "gloop" which can block oilways which may cause an engine siezure (on a 2-stroke petrol engine)
So if you are adding 2-stroke to your 4- stroke diesel engine, best to stick to 1 type of oil (Castor based / semi synthetic or synthetic) - or one make of oil to be on the safe side
Castor based is an old type of 2-stroke it tends to smoke more and cannot withstand high tempratures as well as the other 2, synthetic tends to be more expensive than semi- synthetic
Some oils are expensive and adding 2- stroke oil will add to the cost of running your diesel - for most people, the bio-diesel added to modern diesel should be sufficient to lubricate your pump, injectors etc - adding a little 2-stroke oil (and sticking to the same type/ make) is unlikely to do the engine any harm (as long as the oil does not react badly with the diesel) the oil has a zero cetane rating (no calorific value) but is being added in such small realative quantities that this will not significantly reduce the overall cetain rating
Try a little low-ash 2-stroke and see what happens - if the engine runs smoother, quieter and faster, without increasing the smoke output - its all good , let us know how you get on, anyway

Keep you updated.
If it is succesfull, I will follow.

In general he is satisfied.
There has anyone reported that he's doing the test for allmost 10.000 kms, now
his findings: from first addition indeed quieter stationary running , nailing cold engine almost completely disappeared,
fuel consumpsion: 0.5 L/100 kms less
I am convinced of the benefits of this addition.
I will follow

Positive results so far, but it is only the beginning.
The results so far: smoother running, not nailing(is it the right word?) at cold start....
consumption: less then before ( cc 120km/h 6th gear: current 4.0 - 4.4 L/100 km (unbelievable, but true) - before aprox 5.0 L/100 km. But, as i've said: this is only the beginning......
As I increased speed upto 180km/h, consumption rised smoothly upto 5L/100km .........
