2SO isn't the fluid to add to any diesel engine
...its not formulated or made to dilute with diesel
...negligible advantages
...significant risks
so why risk you D3/4 engine ?[/i]BREXIT - done properly.

2SO In Diesel
Ok fellow Discovery enthusiasts I have heard the good and the bad about adding two stroke oil to the diesel. I have just added 500Mlts to my full tank of fuel. I have no thoughts either way to weather it’s a good idea or not. I will run the car for a month and see if I have any advantages that have been stated on the forum.
I will only add 400mlts to the next full tank and will let you know my personal unbiased opinion at the end of April.

Quick update from me;
Cold starts definitely continue to improve, for the sake of accuracy I always make sure to test cold starts early in the morning when the temperature is roughly the same or not far off from the day before. Before 2SO engine really seemed to struggle (likely needs glow plugs) but with 2SO the engine seems to turn over much more smoothly, all the awful sounding spluttering to life noises have almost disappeared.
Engine noise overall has definitely improved significantly. Over the past few months I've been thinking how loud and tractor like my Disco sounded (especially when sat in traffic with the windows down). Disco has been running with 2SO mixed in for 4/5 days now (though admittedly has covered a lot of miles in this short time) and I'm really surprised with how quickly I'm seeing results. Awful tractor like noise has gone and engine seems very smooth, especially when ticking over in traffic. I was driving home yesterday when the CD changer changed CD's and music stopped playing, I had to do a double take as there was barely any engine noise - I thought I was drifting along!
I've also noticed that the Disco seems to have found its legs again, I am definitely seeing an improvement with acceleration/pull.
Sounds really weird but exhaust smell has also improved seems a lot cleaner and less likely to make you cough or whatever if you're walking behind the car with the engine running.
Really can't comment on MPG as it's not something I often keep an eye on. Though I used to go on the Motorway, set cruise to 70 and reset the MPG counter on the computer and would roughly see around 30-32 MPG sat cruising down the motorway at 70. I did this yesterday with 2SO in the tank and it returned 36 MPG - therefore could be an improvement with MPG also.
My main reason for using 2SO was to improve cold starts and engine noise, I can safely say it has definitely worked and I suspect after a couple more tanks will continue to improve.
Overall I'm very happy and impressed.
I appreciate everyone is entitle to their own opinion and adding 2SO definitely attracts controversy, I must admit I added it to the tank for the first time and thought it would make absolutely no difference, but the results I've seen speak for themselves - it's definitely doing something and so far I've not had any sort of signs from the engine that it's adversely effecting it, all the results I've personally seen have been positive.
Until someone can prove with absolute certainty that it adversely effects the engine I'll continue using it religiously - So far I've not seen any comprehensive arguments against 2SO that can 100% confirm it will cause problems, they're all "potentially" this and that - meh, I could "potentially" drive into a wall tomorrow and damage the engine that way....

For all this, isn't it better to spend an extra 5p per litre for the Super level of Diesel?Dave
D3 2006 HSE, Cairns Blue - gone
D4 2016 SE, White
I have covered c. 78k miles since taking delivery of my D3., and have used Shell V-Power diesel since day 1.
MPG, accurately recorded, for the first 35.5 k miles was 24.1 MPG.
Thereafter I have continued to use Shell V-Power and have added Castrol Actevo 2 T - MPG overall, ab initio, has risen to 24.7 MPG - so an improvement of c. 1.2 MPG
I shall continue to use both Shell V-Power and Castrol Actevo 2 T.
Car is manual with BAS re-map & is driven hard.

Makes no difference, I run the car on BP Ultimate most of the time anyway. Only saw the above benefits after adding 2SO.

Hi guys, I have this 2 stroke oil for my petrol generator, would this be OK to use, I'm going to Wales for the BH weekend and would be a good run to test this out?

Hmm, here's an interesting argument against using 2SO, could lead to increased injector nozzle deposits and DPF damage, have a read and make your own mind up
MANY thanks for this informative paper, Dave T.
Not only does it confirm my scepticism expressed in the early days of this thread.
* At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel cetane number.
* No measurable effect on all other regulated diesel properties was measured at a 200:1 dose of 2-stroke oil in diesel
But worse than that, as the experimental data seems to demonstrate:
* 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.
It would seem that not only does the addition of 2-stroke oil have no benefit despite its cost, but it will lead to otherwise unnecessary / premature, expenditure.

For All Series LR and Disco1 and 2 a Jaso-FB rated oil is fine; however for Disco 3 and 4 a JASO-FC rated oil has to be used
I think this came from "HonestJohn".

I used 2SO on our previous A3 2.0 TDi (PD engine), and it made a *big* difference - less tractor-like, less black smoke on heavy acceleration, etc.
I started using it in our Puma 90, and it made less of a difference, easier starts on cold winter mornings, but that was about it. However, I always carried a spare bottle when driving in Namibia and in rural areas as you never knew if they were spiking the diesel with paraffin. So in this case, the main use was to prevent damage/provide added lubrication should the diesel be dodgy.
We bought a new A3 in 2014 (CRD engine), and a D4 in Oct 2015, and I have not put 2SO in either - IME, it has very little benefits on such high-tech engines.
However, if you think you put in some dodgy diesel, by all means, add a bottle as this could mean saving a pump/injectors.--

I don't really understand the people posting data saying there's no evidence it does anything, this thread and the several others elsewhere are scattered full of people saying they've seen benefits, okay these benefits may not be scientifically backed but surely all these people haven't had some sort of giant brain fart leading them to believe it's working?
It must do something, else why would so many people (including myself) see positive results?

Each to their own, but what hidden effects is it having - that could be good or bad. To make an informed decision on whether to use it or not you first need to hear both sides.
For me, I choose not to use it in my car, anyone else can do whatever they want, just have the information.

I stopped using it about a year ago as I couldn't get Actevo - started using Millers Diesel Ecomax instead at suggestion of Opie Oils - use 80 mls a tank full - feels better than 2TSO and mpg up by about 2.5 on a constant run.
Smoother starts, no smoke (better than 2TSO) and 2 Mot passes
And it's cheaper and more convenient to use
