2 stroke

Post by xantiagreen »

Brother ended up buying a 2006 V70 D5 185bhp with DPF 7 seater, with 160k but 1 owner with full main dealer volvo history, its a cracker on motorway but round town it's a curse. I ended up shoving some Lucas 2 stroke low ash semi synthetic 100ml to 30 litres of diesel after reading a few articles and a week on its quietened the engine on tick over and it fires up quicker and hardly any smoke on full throttle.

Do the xantia 110's have the stomach for a mineral 2 stroke low ash mixed with diesel and has anyone had any good results.

Cheers

In small doses it should be OK... After all, diesel fuel has a lubricant added to it at the refinery to ensure injection pumps are properly lubricated in service...

Years back the natural sulphur in diesel acted as a lubricant but with the advent of low sulphur fuels a problem with failing injection pumps emerged and this was corrected by adding lubricity to the fuel.

On that basis, in small amounts, a high-quality 2-stroke oil should be OK. It'll be interesting to see how it goes...

I note a lot of modern diesels now sound like bags of spanners when ambling round town and on idle... Nothing like the sweet sound of an HDi :)

I recently fitted a new pump to my Rayburn cooker/boiler, it had a note posted on it to the effect that it could seize up if you didn't put some oil in the fuel, this apparently applied to certain parts of the country but they don't tell you which parts! I haven't, so if it seizes up I will let you know. :?

Many people say that mineral 2 stroke low ash mixes perfect with diesel and doesn't separate and settle, semi and fully synthetic does not mix well and will settle at the bottom of tank and if that gets sucked in then you're getting a higher dose of 2 stroke which can cause possibly cause issues. Is that true? I know it's only been a week on the semi synthetic but I'm dreading anything going wrong with the V70 as I use it now and again :) I've noticed some drivers brake as soon as they see the V70 and I have been known to talk into my left shoulder when I see a brake happy driver...

As a frost/thickening protector I would think. Nothing wrong with the lubrication of fuel oil

It should always stay mixed as most fuel pumped to the engine gets returned to the tank so it keeps getting mixed.

For what it's worth some always goes in my xm, 100ml to be exact and some in the rangey I drive.

It does help make the engines that little bit quieter I have found, not as quiet as good bio did but still worth it and mpg doesn't suffer from it and as I have a 20litre tub of fully synth two stroke I can spare the odd 100ml per tank :D
If you search freel2.co.uk and 2SO then you'll find a nice big thread about it.
A lot of landy owners are using it so it can't be that bad and in low amounts doesn't seem to affect dpf's and with the Citroen system it shouldn't be an issue.

Must admit this was new to me (& I thought I kept up the Landy scene) until a month ago, when someone mentioned adding (if I remember rightly) 500ml every 70 l of fuel (didn't occur to me there was synthetic 2-stroke, so didn't ask). Thought I might try it come the cold weather, when I'd be reluctant to run on 10 - 30% veg oil, which I thought had had a similarly beneficial effect. Certainly the old tub seems to run better now, whether there's any oil in the diesel or not.

I run 250ml oil to 50 ltrs of diesel in both my Xantia and Jag S Type. They seem to run smoother as to improved mpg I couldn't say. But then again I used to put spotlights and go faster stripes on my cars in the 70's and they used to add at least 20 mph to the top speed of an 1100cc mk2 Escort :-D

Got some in the Barge after reading this. So far not noticed anything really! Maybe when the tanks done it might be obvious!

I first heard of this years ago on the UKSaabs forums, and have been running 200ish ml per tank of it in my Xantia pretty much since I bought it.

While I can't quite figure out the chemistry behind it, there's a definite reduction in full throttle smoke when it's in the tank and it definitely reduces idle clatter when warm (doesn't seem to make much difference from a cold start). Performance wise I'm not sure whether it's the placebo effect or not, but it seems as though the engine feels a little more willing with the 2-stroke in there...definitely not a really noticeable difference though.

That's on a 1.9TD though - imagine keeping the dosing lower may be more important on later cars with DPFs etc.

definitely an essential additive if you fall victim of the "old VW" advert of a few years back................Ie topping up with petrol, instead of diesel......
I did that,17 litres into a Ducatto Van.........
