two stroke oil in the diesel ?

[redeemer]

I used acetone, and two stroke but I put very few two stroke by mistake ! (I have read 30ml instead of 300 ml )
I calculated the mpg some time ago , before acetone and 2stoke, it was something over 30's ,because I didnt filled up to the brim, but relied on the gauge
Now I made a fairly acurate reading, filing up to the brim and at the next fillup take out the liters and milage.
With acetone and 2 stroke : 32mpg
using the conversion of 1 gallon (uk)= 4.54 Litres.
Also now I added the dose of acetone , and instead of two stoke I (because I didn't have) I put 300ml engine oil, and it works quite good, giving smooth ideling and less injection pump noise!
Now I used the dose of 1.56ml acetone per 1 litre of diesel, and it will be better that the acetone will have some % xylene.
adding more the dose will not improve things, but it would be worse! I have read this in an other site.
Now im trying to guess if this is all a fuss or not!

Going to give the 2 stroke a try have a MK6 (53) Tourneo 2.0ltr (125) worked out the ratio for the mix is 4.5ml per litre of fuel will post any results on noise reduction or MPG when I have them, is anyone also using it in a MK6

hi there, just been reading all of these posts,, i run my lwb 1995 transit,, oh diesel and rapeseed oil,, 1/3 diesel to 2/3 rapeseed, i find it has more power than just diesel,,, would two stoke oil work for this too??. ....

I run my Di similar but tother way round, 2 parts diesel 1 part new rapeseed oil, quieter and more MPG (5ish), deffo idles smother as well and cold starting is better as well.
In fact it runs how the Di used to run back in the day, before low sulpher diesel
I've tried 2 stroke cos i had a few bottles laying about with same result, used the acetone but TBH after the first use even without it the results were very very similar, my reconing was it simply cleaned the fuel system out.
I got the exact same results in my TDi disco (and still do)

Tried 300ml twice in tank before filling tank up full. This is in my AutoSleeper Motorhome ( 2.5TD, Automatic, Epic System) was pretty quiet before, but now the engine is even smoother and more

quiet. Tried the third tank with 300ml when going down to Peebles for 'Slippy's Scottish 09 Forum Meet', smooth as silk, 3.5T loaded and doing 70mph in places. Now completely convinced and will

continue using every third tankfull.

Have some mpg values for my mk2 2.5di turboed with Lucas Cav pump (until conversion ).
183 miles ==> 25.26 L diesel
after the last fillup I put 300ml engine oil 15W40(didn't had 2stroke oil) and 110ml Acetone. using 1.56ml per 1 Litre diesel.
result 40mpg
Never achieved that before, and these last two weeks he was driven with a hard foot heavy accellertion in morning traffic.
If you reduce some errors in reading say it come 36mpg, SO Acetone does work with the right quantities. I proved it for myself.

I'm using stroker oil and have notioced around a 2.5mpg increase in economy.


I've always been wary of acetone though as it will eventually rot gaskets

Just a thought how much does a plastic bottle of normal 2 stroke oil cost 2 or 3 pounds that would buy half gallon of extra diesel so that would give 15 plus mpg more as i say just a thought why bother ?

[GBBiker]

A valid point marauder but for me, it's more about the fact that I can now have a conversation with a passenger and hear the ICE at motorway speeds. The noise levels of the engine have dropped by, in my estimation, around 30% since I started using 2 stroke.

[Marauder]

As you say valid pint,especially since taking the arm off that goes from pump to EGR and cable tied the inlet butterfly open the induction roar is realy loud over 50 mph is every body else induction roar loud when disconnected egr ?

It's suggested that the reason for using it is to combat the lack of sulpher in modern diesels, sulpher acts as a lubericant, but is almost gone from diesel now, fine if you own an ultra modern couple or 3 year old diesel (they are able to cope, I suppose it's a bit like when the leaded, went unleaded!), but older stuff doesn't have the hardened parts to cope with low lube.... extra MPG is just a bonus.... quiter smoother running and protection being the first
Still using it in mine, sometimes every fill, sometimes not (because noticed at every fill after a while I was getting a poof of smoke on start up, like a two stroke starting).

[redeemer]

in the last fill up I used engine oil, and the difference is the same as using the 2stroke oil. Its usage is because as said by darkbluevanman , low sulphur diesel because of emissions when the sulphur is burnt. Acetone then just loosen the surface tension of diesel, therfore it will burn completly.
just a small comment, apart from the bad stuff is accosiated with the Cav pump, I think when economy is a priority, it is the only option. I had touched the pump auto advance device, and the diesel specialist said that it would consume a lot of diesel. So when in good nick what will be the mpg? better

Well, after doing a couple of hundred miles in my new van (2000 banana) I had been very pleased with the noise level and the power of engine. Even though I havent done the EGR mod yet, I thought it was very sound and at 137700 miles had clearly been very well looked after.

Today with the reserve light on again, I invested another 20 litres in the tank and threw in 100cc of synthetic two stroke for good measure - I wasnt expecting much really, but 3 miles down the road I was gob smacked. It suddenly became a different engine. No change in power at all, but it was as if someone had just filled the bonnet with sound absorbing foam.

Got to admit I got a bit excited - talked in a normal level voice with the window down at fifty. Wound the window up and tried whispering. decelerated for a thirty zone and wondered if it wasn't the 2 stroke oil after all but that my engine had gone catastrophically wrong - there was almost nothing to hear!

I love this site. Gonna try the EGR mod on Monday - having had a look, it looks trivial to do.

G'day I have just run half a tank with 110 mls of motul synthetic 2 stroke oil, yep I would agree it makes a very noticable difference in alround performance.

Sorry just found this thread Interesting read this. But is it worth me trying 2 stroke mix in the mk7, as there engines r designed to run on low sulphur diesel

I wouldn't, could knack the cat?
