Redex in diesel?

[badfelafel]

I have a 3.0tdi and wonder if anyone has any experience of adding redex. Its supposed to clean deposits off injectors etc.

Sounds good... but is it completely safe to do ir worthwhile?

Thx

If you eat enough hard boiled eggs you can live without breathing

I have a petrol, but I've used Redex and Wynns petrol/injector treatments and the wynns always gives me the results for what you can get in a drop in 'cleaner', never had any great joy with Redex.

Might differ with diesel though - no experience with that in particular. But for general carbon removing wynns always does well when soaking things for me.

Is your car showing symptoms of anything or just as a maintenance type of thing?

I also use V-power pretty much exclusively these days, so it all helps.

[badfelafel]

Its just for maintenance, it runs well just now and has been well looked after. Nothing to do with boiled eggs!

[Doctle Odd]

If Redex works so do the eggs!

[badfelafel]

Ah I get you now!

[lynalldiscovery]

Lots of people are using 2 stroke oil in their diesels to make up for the lack of lube in low sulphur diesel try a search.
Ive been using it in my disco and wifes 3.0tdi, does it make a difference? cant say Ive noticed in the disco but have noticed the A4 seems smoother.
But at just over a quid fifty for each full tank of derv Im going to keep trying it for a while.

[OVI82]

Millers is another good one which I have been using for a while now.I only run my car on Shell V power and add a dose of millers only if I'm going for a long journey such as next week in Utrecht(Holland) for ASOT 700.Did the same with the previous A4 and never had any problems and I do believe it helps.As for the eggs will leave them for after the gym....and as many as possibille.

i wouldnt use 2 stroke oil in a diesel engine, it contaminates the engine oil.
if there was no negatives in doing it the 2 stroke manufacturing marketing team would be jumping all over it and make their company millions extra a year. the fact they are not is evident for me that they know it either makes no difference or has negative effects. these marketing people arent idiots.

[lynalldiscovery]

I assume you have evidence to back up the oil contamination claims? As its mixed in such small quantities with the derv how come the derv does not contaminate the engine oil?
If so would love a link to see/read it myself.
Changed wifes 3.0 oil and filter the other day never noticed any weird smells or texture to the engine oil.

[badfelafel]

Did the redex. Seems slightly more sluggish and econ worse! But will see once I've refilled and it gets diluted out if there will be any improvement

So are you saying the hair growth lotions work as I would love some hair:D

Ive been having a no1 hair cut for so long Ive forgotten what its like with hair, still a doddle to dry after shower
Annoyingly a wooly hat is compulsory when temperature drops.

its obvious that with any combustion process that engine oil will be contaminated. if you need to learn the exact science behind it it would be advisable to read up on it.
2 stroke oil is not designed to be used along side engine oils.
if there were no draw backs from the manufacturers point of view they would be advertising the facts, simple.

Im a truck mech and have been working on vehicles for over 25 years so have a little idea how they work, this does not make me an expert, but it tells you I am not a barstool mechanic!
Bear in mind some of the trucks don't get an oil change until 100 plus k and even the slightest bit of diesel in the oil would be bad.
But when I asked for evidence I meant just that direct evidence that what you said is true, i.e. 2 stroke oil is bad news for the engine oil, in fact I would love to see how enough of it could get into the engine oil in the first place, but I think Ive already said that before.
What I would say is google 2 stroke oil in diesel fuel and have a read always worth some extra knowledge.

[white.akita]

Yep I have read quite a bit about placebo effect and how easily people can be fooled.
I have also tried it myself and noticed no difference like alot of people.
If you believe it has benefits and no draw backs don't you think that the marketing departments would be all over it ? Or maybe they should get joe public to do their testing in their passat as it would seem the millions the research and development team spend every year is wasted.
the fact they have all the data of their products and they do not condone the use of it along side engine oil is all I need but hey maybe you know better.

So still no evidence to back up your claims?
Come on Im sure google and wiki won't fail you!

[lynalldiscovery]

Right Ive actually googled 2 stroke oil in diesel fuel and there is page after page of positive results, even quite a good one from a guy in Germany with a Freelander 2 and emissions test.
So to anyone reading this you can believe with your own eyes what your fingers can find on the internet or one non mechs word against it!
Im not disputing some people are going to find fault with it that after all is the way of the world, what I am disputing is your claims that it can mess up the engine oil.




2-stroke oil and diesel



To all interested:
due to the pollution control measures of the EC diesel-oil is nearly sulphur free and contains up to 5% of bio-diesel. Sulphur has the property to grease the high pressure injection pump and the injectors. Without sulphur, the reduced greasing property of the new diesel has already shown negativ impacts on the long-term stability of the injectors and the high pressure pump. The pump manufacturers have tried to react by lining the moving parts of the pumps with teflon or other suitable material. However, the long term stability is still not achieved as with the old (sulphor contained) diesel.
The engine-research centre of a well known German car manufacurer has conducted some long term tests of diesel additives to find out whether any one of them will have an impact on the long term reliability of the diesel engine components. This introduction to explain were my information comes from.
The results of this research: any diesel additive of any manufacturer presently on the market is not worth the money!
BUT: 2-stroke oil, which we use in our motor saws, lawn mower or in 2-stroke motor engines has shown to have an extreme positive impact on diesel engines, if such 2-stroke oil is added to the diesel in a homoeophatic dosis of 1:200. In practical terms: 0,300 litre of 2-stroke oil into the 70l diesel tank. The 2-stroke oil will be absorbed by the diesel (emulsion) and grease every moving part of the high pressure pump and the injectors.
Besides this, the 2-stroke oil will keep the diesel engine clean, as it burnes cleaner as the diesel itself.
In other words, the 2-stroke oil has a much lower ash-content as diesel, when burned. This proven fact delays the DPF (diesel particulate (soot) filter) to clogg, and the "burn free" process of the DPF will be much less.
One more information: in Germany we have to present our cars every 2 years to the TUV -Technical Supervision Organisation - who will check, amongs others, the pollution of petrol and diesel engines.
The measured cloud-factor of a diesel engine without use of 2-stroke oil has been 0,95.
The same factor with the use of 2-stroke oil has been 0,47 - reduction of nearly half of the soot particles.
Besides this, the use of 2-stroke oil in the diesel will increase the milage by 3-5%.

I cant disagree about the 2-stroke oil however I read somewhere that common rail engines don't like it. I still use petrol as a cleaner. 2 stroke oil in Ireland is red and it dyes diesel. This could have serious repercussions as revenue are out "dipping" cars for agri diesel which is green in Ireland and red in the UK. It looks bad when you're dipped and the clear pipe they use turns red.

This topic splits opinion like no other. Now I'm no barstool mechanic, merely a retired Aeronautical Engineer with many years of maintaining civvie aircraft on the clock. Only a few of 'my' birds crashed! So I think I might have been decent at doing my job most of the time. But I still know bugger all about adding two stroke oil to diesel fuel in any quantities!

What I will say is that someone goes on a forum and states that this product/item/additive is the best thing ever. There will always be someone else popping up to state the opposite and then the battle lines are drawn. I take the view that there is probably more water present in a tankful of diesel than the proposed amount of 2 stroke, that would be added. I doubt that this 2 stroke product would kill off an engine. I also doubt that it would do much good, bearing in mind the tiny quantities that are been added. It's one of those topics a bit like Seafoam or Slick Fifty ect. Everyone has an opnion, but very few everyday folk (including me) REALLY know if the products have any benefit to their car's engine.

I suppose if you want to improve your diesel engine the only way would be to life the injectors and the pumps, fittings, seals, pipes ect, to say 60,000 miles or six years between overhauls or renewal. I wonder if that would make any difference to MPG figures and emission outputs? How quickly do injectors block or wear? What effect is this having on performance/ emission output?

As for Google, well let's just say that there are some very odd stories written by some very strange people. I'll be kind and say that some are genuine, whilst others have very fertile imaginations.

Hang on a minute though

How many on this forum are using this 'break through technology? After all there are thousands of these HHO powered cars in Japan alone, there must be millions in Europe. Anyone ever run their car on HHO? And saved all that petrol/diesel

I saw a similar product on a well used Irish website. I'm impressed so impressed I'm going to look for one today. 100's of satisfied customers here!

[white.akita]

there may be some benefits of using 2 stroke oil in diesel, but you can guarantee that by the manufacturers quiet standpoint that even if they did do some good that the negatives outweigh the positives other wise obviously from a buisness point of view they would be all over it, its laughable that people think they just haven't bothered ha.
if anyone does need links posting for obvious things like how 2 stroke oil once burnt contaminates engine oil then maybe they should do their own reading.
just to reiterate , it may do some good but that doesn't mean there are no negatives i.e contamination for one ha.

[Doctle Odd]

Apart from the none that I know of do any of the additive manufacturers offer a guarantee or refund?

I think they look for more than the colour Im sure there is a chemical dye in the red so even when its been through fullers earth to get rid of the red dye they can still tell its red derv.

As an aside Ive just come Back from Norfolk and best mpg yet in my disco since using the 2 stroke oil, I have to admit not by much 2mpg extra and we all know that could just be the temp or the wind, but still makes me feel good!

There is a whole thread on 2 stroke oil with hundreds of replies (not all positive) over on the disco3 forum and they are all common rail engines.

Shell V-Power?

:biglaugh: :biglaugh: :biglaugh:

I tried a tank full of that in my A4, it was a bag of *****! I lost power and MPG, I also had to rev the guts out my car to get it moving. Cold starts took at least 2 turns of the key.

Best petrol, (in my experience), is Asda; I get more power and a much better MPG plus cold starting is a lot keener.

With regard to redex, forget it or any other additive. If you want to clean a diesel engine put a gallon of unleaded into the tank and run it. I did with my van, (well, it was 16.61 liters actually by the time I'd spotted what I was doing), and it ran like a bag of spanners.

Before the unleaded mistake I was getting on average 30 to 32 to the gallon, since the unleaded mistake I'm getting 42 when full loaded, 38 unloaded.
