@ron p, yes it does matter, fully synthetic does not mix with the fuel, stick to jc mineral or semi synth, either one, but not fully synthetic and if you have a dpf not jb,

Can anybody estimate the increased Sulphur content by adding the 2T in the ratios discussed?

Err, no sorry

I thought the problem with S'efrican fuel was too much sulphur, does 2sO add more?

I have no technical knowledge on this matter but I guess adding the 2T in the ratios recommended is surely not enough to raise the Sulphur content past the threshold of 0.3% if the original ULSD is <0.001% (This would equate to x300). It would be interesting to know what content it is tho when people have experienced such notable improvements in performance.

Hi Divlar

there are some misconceptions out there regarding sulphur's "lubricating" properties.

The problem with ULSD is that in the process of removing sulphur from the diesel, the lubricity of such diesel fuel is substantially reduced. This is also the main reason for the rise in HPFP and injector failures past 130'000-150'000km.

There seems to be a correlation between early failures and bad "stretched (with paraffine) diesel. These problems are endemic in Southern Africa north of its borders, and are also well documented in Eastern Europe.

The solution is the addition of Jaso-FC compliant 2sO in either mineral or semi-synthetic formulation.

To all:

Def: yes, fill in 0,3 litre of 2-stroke oil with every tank filling. You will notice a surprisingly big difference in the smoothness of your engine running, the noise level is reduced, particularely when the engine is cold, and the fuel ecconomy will increase besides the described other advantages.
The 2-stroke oil I can recommend from my own experience (value for price) is the Liqui Moly 2-stoke oil, semi-synthetic, Product no. 1052 (blue plastic bottle). The use of 2-stroke oil is recommended also for diesel engines without DPF. If you "forget" to fill in the little dosis of 2-stroke oil - no problem. Just fill it in the next time.
Everybody who has used the 2-stroke oil in his/her diesel engine has confirmed that they could not have done better.

Evanessen: see above. Do not use fully synthetic 2-stroke oil, as too expensive, and you do not really need this high quality for your purpose. Semi-synthetic will do.

npinks: the use of 2-stroke oil in the diesel will under normal circumstances not be evident, as the 2-stroke oil will be absorbed by the diesel by forming an emulsion, which will not seperate.
As I have said, we have to undergo every 2 years a pollution control inspection by our TUV, and the emission values as measured are by far better with use of 2-stroke oil than without. I have not come accross any case in which a car manufacturer has waived its guarantee obligo for cars which have used this 2-stroke oil (off course, not knowing this).
Dismantling the test diesel engines after the 2-stroke oil test has revealed that such engines have been in an extroardinary clean and top condition. So why should any car manufacturer have any reason to waive any guarantees (for whatever technical reasons) if the concerned engine is otherwise in a clean and top condition.

There you go, looks like ANY 2-stroke oil will be fine, as long as it is low ash

Semi Synth is ok
