Anyone adding

[joinerman]

Two stroke to their deisel on fill ups, read a lot about it on other forums & thinking of giving it a go.

 

[Gary Stockton]

What are the benefits supposed to be?

 

[joinerman]

Makes the engine run smoother quieter more lubrication for the pump, cleans the injectors.

Below is something iv'e nicked from another forum.





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 also dug this up from another forum, apologies for plagiarism to the original author.



I did a lot of reasearch on 2 stroke oil in diesel engines.

It seems our american cousins are already wise to the benefits of a drop of 2 stroke oil.

Anyway the science is well proven , it burns more completely than diesel , reduces engine smoke to virtually nothing , cleans the combustion chamber , it appears to lubricate the egr valves to close more evenly.
(I had a lazy egr valve one side but it's not lazy any more)

You can buy 2 stroke oil cheap enough on ebay , from wilkinsons or b+q.

I've used it for a few months now in my RRS and the wifes A4 tdi.
Much quieter when cold ,much better throttle response . no smoke unless I drive like a test pilot when I get a light haze from the pipes instead of the smoke I used to get.The throttle response is thebig difference.
It is more lively and the gearbox doesnt hunt up and down at all.

just 300mL of 2 stroke oil in a full tank really does give you wings.

I've got my dad using it in his Mitsi L200 navvy wagon , same story.
Neighbours ford focus , different motor!!
Mates escort diesel van 1.8 , much smoother +quieter.

Any questions ask away , I've had such success I thought it was my duty to report it.

I've done a fair bit of research for bulk buying , I wont post it as it might be construed as commercial posting.

It's such a small percentage of the full tank it can do no damage and dissolves completely.

I dont see how we can lose.

I haven't added 2-stroke oil to the fuel.

But I have noticed there is a big difference in the fuel you get from the pump.
I monitor mpg at every fill up and you tend to notice a trend when fuelling at certain pumps.

Different brands give different mpg, usually the more you pay the better mpg you get.

Same brand different stations, the station which delivers higher volumes gives better mpg.
Like those located on the highways catering for the trucks on a daily basis compared to the local village station catering for the locals.

2-stroke, full mineral, semi-synth, full synth???
If there is a brand out there that will turn my cruiser into a V-12 formula one engined elephant with the appetite of a squirel, please tell

Modern diesel fuel has almost zero lubrication..... that why I always add at least one 3 liter bottle of rapeseed oil to every tank full of fuel

 

[Andrew Prince]

I have been adding around 200ml per fill up (i guess around 75-80l derv per fill up) for the past year but have not done for the last 3 or 4 tanks as I ran out of 2stroke. Truck seems to be smoking a tiny bit more without it and mpg seems to be slightly down - couldn't say whether the 2 were related as its not a daily driver. I am not 100% convinced that 2stroke is necessary/important but I figure there's not much to lose on the off-chance there are benefits for the engine.

 

[Gary Stockton]

Would that be good on the D-4D engine as well then??

 

[Bat21]

I'm not sure if the D-4D is common rail?.... my understanding is it will only be of benefit to engines with the old rotary type pumps.

 

[Andrew Prince]

I'm with Paul I wouldn't put any in your D4d - it's designed for modern derv zero and seems rather finicky about the fuel going through it. Our older engines prefer the full fat version or a bit of 2stroke to up the calories

 

[silvercruiser]

yes i use it and it does run smoother.

 

[Towpack]

I usually use either Castrol Power1 or Actevo 2 stroke at @ 200:1. I personally wouldn't use unrefined veg oil due to the glycerine content which has been shown to gum up rings/injectors over time. IMO modern 2 stroke oils are perfect for the job, good lubrication and virtually deposit and smoke free.

 

[Rob80vx]

Sounds good, so is 300ml of 2stroke to a full tank about right?

 

[silvercruiser]

Thats what i use per tank and all seems good.

Just another urban myth? I don't know. There is a lot of really good info on this site and on the web in general. But it is all hearsay with no accountability. Trouble is people "at the top" who know the answers will not say. And that is true not just on this thread's subject but in all subjects. I'm not running anyone down.

Doesn't diesel fuel have to meet certain standards including lubrication qualities or not. Or have the goalposts been moved?

I'd love to know the truth, the whole truth and nothing but the truth.

[j555fjr]

a friend of mine uses a small amount of hydraulic oil in his diesels and has done for a while, he says he noticed the differance right away. mind you he also ran a golf on celly thinners for a while when he was skint!

 

[Andrew Prince]

Sounds good, so is 300ml of 2stroke to a full tank about right?

The general chatter seems to be adding at a ratio of around 200:1. Adding 300ml per 60l would be 200:1 Can't say I've been scientific in my approach - I've crudely tried to add 200ml per fill up but that generally ranges from 70-80l but thats more like 400:1 - maybe that's why I haven't noticed a life-changing difference using 2stroke!

Just another urban myth? I don't know. There is a lot of really good info on this site and on the web in general. But it is all hearsay with no accountability.

I think it's more than hearsay as many people are adding 2stroke but I agree with you that there isn't a lot of truly scientific measurement going on. The same could be said of injector refurbs - while I am sure some refurbs make a huge difference, lots of people have had injectors redone and said "wow the truck was so different afterwards" when there is no real measure so highly subjective not to mention the placebo effect

Doesn't diesel fuel have to meet certain standards including lubrication qualities or not. Or have the goalposts been moved?

Diesel does still have to meet certain specs, including "lubricity". The big "but" here is that diesel is a big mix of various hydrocarbons and lubricity in old diesel was provided by a combination of chemicals. Modern ULS diesel has a lubricity additive, which I imagine is simply one or 2 hydrocarbons and these are added to meet the lubricity spec, but NOT necessarily to match the actual lubrication performance of old diesel. Older diesel engines of course were designed around the standard diesel formulation of the time. Just like modern common rails etc are designed for modern diesel with its lubrication additive. The question in my mind is what is the consequence of long-term use of modern diesel in older generation engines. Obviously this is an incredibly difficult question to answer scientifically because any damage (increased wear) will occur extremely slowly, so hard to quantify. And how do you create a control where you run the equivalent engine on old style derv in order to have a proper comparison?
A quid's worth of 2stroke per fill up seems like relatively cheap peace of mind, even if in practice it doesn't do anything - plus there's the benefit of the placebo effect

I'd love to know the truth, the whole truth and nothing but the truth.

Wouldn't we all - I think this is one of those debates destined to rumble on and on.

 

[Chas]

I usually wait for the light to come on before I fill up and then add 500ml of two stroke, so that makes it er, er, something for all you [strike:3ohno2dq]mathimisms[/strike:3ohno2dq],[strike:3ohno2dq]mathmastics[/strike:3ohno2dq] number crunchers to work out

 

[Gary Stockton]

Hey Andrew - if you tell the DVLA you run your 80 with 2-stroke maybe they'll re-classify it as a motor-bike for you - no more LEZ worries then?

you say unrefined veg oil. do you mean waste veg oil?

ive been running on new veg oil from macro's, booker's, tesco, asda etc. for a few years without any problems.

my mate has done 35,000 miles on veg oil in the last 2 years in his hi-lux and he hasnt had a single problem.

i know Karl has done a lot of miles on waste veg, and the only issues hes had are having to replace the fuel pump occasionally.

because of my experiences running on veg oil, i dont believe the myth of it gumming rings up, or any of the other myths about veg oil which is on the net.

new veg= 90p litre. diesel= £1.40 litre.

 

[adrianr]

HI Ben

Where are you getting the new veg oil at 90p please?

THank you
