Bought some 2SO from Wilko Tuesday. Put 300 ml in tankful and consumption
has gone from 29.1 to 36.7. Pleased with that!

If you believe 2SO was solely responsible for that then book an appointment with the men in white coats

I'm interested in 'maybe' its other benefits, sod the consumption

Well... reading this and other forums (fora?) I see plenty of admittedly anecdotal evidence in favour of 2SO as a modest additive, but no-one reporting any consequential problems, early component failures, wear, or degradation. On that basis, I'm giving it a punt.

On the other hand, no official endorsement has appeared anyplace. That's perhaps because (i) manufacturers know that it causes no problems / actually improves engine longevity / performance but can't say so for various (green / legal advice / legislative) reasons; OR (ii) manufacturers know that it can cause engine problems but can't say so for various (legal advice / legislative / marketing) reasons...

So, any (semi)-official responses from oil companies, engine or car manufs would be a real help but I don't think that's on the way.

So, I will finish the current 1L bottle of Castrol's finest JASO-FC and try & get a sense of engine performance, noise & mpg. After that, I'll stop using it and see what happens to the above measures.

Anyone done this already? Be intereted to hear if anyone's used 2SO then gone back to not using it and can report findings.
EDIT ... and I'm not inclined to accept a 29->36MPG improvement... Something else at play here, methinks ...

Be true to yourself. That way happiness lies...

My only input on it is when 1st got the car it was doing what i class as a poor 22mpg freelander or not.After reading this thread i was left undecided bout the whole thing but could only thing how can it do any harm,In my mine it cant!
I then decided to run 3 tanks thru the system just to clear things out a bit to try get the mpg up a bit(more or less 1ltr of oil)

After doin it the mpg is now up to around 29mpg(warmer weather could play a part in this aswell),After the 1st tank full i can say i didnt see it drop below 25mpg (still had the cold weather at this time).Also i can report the same as others and say no smoke to be seen on start up.Wouldnt like to comment on it been any quieter on start up from cold as this was done when the cold weather was here so unable to give a fair report on that at the mo.

Ive now prob put another couple of tanks of neat fuel thru the system,mpg has stayed the same but (29 ish) but over the last couple of days ive noticed a bit of smoke on start up so im goin run some more 2 stoke thru it just out of intrest but im 99% sure this will clear again with the 2 sroke back in the system.

As regards my higher mpg my feelings were the car was choked up with carbon and what ever else as eveything else had been checked over,If this is the case the 2 stoke has clearly helped no end.I will also say i drive the car a bit harder than i did,Not that i ever go over the speed limit

If some one asked me if i thought it was a good thing or bad i would say good hence i will be running some more thru the system.

Ok, I believe in the use of 2 stroke oil and have used it for many years. About to get a new LR, should I use oil from the start or run-in first?

I have added 2so to my My2013 from 1500miles and is now at 4500 miles.Have not noticed any difference at all.
As it is a new clean engine that is prehaps why.It will prehaps have long term benefits in keeping the engine clean and possibly increasing the longevity of the fuel pump.Difficult to tell even in the longer term though.

One thing I have noticed since using 2SO in my non DPF car is that the tailpipe is not as sooted up as it used to be. I guess it must be running a bit cleaner which would also explain why the smoke test result at MOT was better than last year. John

Castrol ActEvo 2SO FC grade in ASDA for £4/litre.
OK for DPF, bought a couple of litres to try this out.

Bl dy hell!!! That's good. I've paid £8.99 from Amazon for the same stuff.

Having run a couple of tankfuls without the addition of 2SO, I have to say that subsequently there's a marginal increase in diesel clatter & acceleration feels slightly less smooth so will do another tank then go back to adding 2SO & see if I'm deceiving myself  ...

Be true to yourself. That way happiness lies...

Yeah I'd be interested in your feedback, I have been waiting for what I deem as a fair price to pay to try out this 2SO business. I went there as a favour to my wife and like most men I looked around the car bits, obviously a limited time offer so grab it if you can.

It doesn't say it in the description spec but it is FC as stated on the back label. http://direct.asda.com/Castrol-Motorcycle-...lt,pd.html

Nice one Eyorkshire! Just order a couple of litres to pick up from my local store. Was previously using their own brand at £5 a litre. John

EY, Looking forward to hearing what you think once you have added the 2SO. Have you put it in yet?

Yes, I glug glugged about 300ml in and filled up with diesel (I am now officially poor), not interested as such in any fuel saving although that would be a bonus but I won't know because I won't check.

More interested in an improved 'quietness' maybe of the normal diesel clatter, and of course any increase in 'smoothness' by a better detonation, so I'll give it a few tankfuls and report back.

The longevity of the engine and its bits and pieces I'll probably never know, but again it will be a bonus if it never goes wrong
