Adding 2 stroke oil to fuel - Interesting reading!!

[GoLfMan]

in that case, I'll hit up my mate at Peter Stevens motorcycles to get me some of the nicer 2stroke

Guy's I posted the original link to a biofuel site I use and this was one of the
reply posts below.


"Before I switched my boat and tractor to BD, we always put 2 stroke in the Dino after they removed the sulphur. This was recommended by a GM marine mechanic and it certainly made a difference to the engine operation, it was much quieter and smoother running. Our local long haul trucking company uses 2 stroke in their fuel as recommended by their Volvo mechanic.

The marine mechanic said even though they had hardened the valves etc in new engines, it still doesn't stop the extreme wear that comes with what he called the "sandpaper fuels of today". He reckons fuels of today are extremely harsh and designed like the average consumer goods, creating short life times in fuel systems and engine components which adds to company profitability, that's why parts for today's vehicles are so very expensive and dodgy.

A pretty reasonable observation when you consider the life of a car today is about 1/3rd of what it was 50 years ago. Fuel economy is not much different to 40 years ago, in fact in lots of cases it's worse as engines of today are lucky to make 100000klms before needing a major costly service or repair.

I reckon when you deal with profit manipulated commodities, you take no notice of the propaganda nor rely upon so called sales or company experts and look at the situation realistically. After all, we all know what an expert is, X is an unknown quantity and spurt is a big drip."

That's believable???????

[Preen59]

That's believable???????

I think he probably means value for money. What you pay versus the life span of the engine..

That's not 100% correct however.. For instance, my old man services an early 90's BMW 525i with over 400,000kms on the clock. Original engine. Uses bugger all oil between services and only has a bit of gudgeon noise at idle..

While I was waiting for my car to be serviced the other day, I noticed an approved VW diesel additive (Wurth?) and thought I'd might try it.

I don't think I would contemplate dumping 2 Stroke oil in the tank, though.

I agree with Transporter. Interesting find, but a big risk for little gain.

Hi, i would try millers diesel power sport 4.
Diesel is a lubricant, unlike petrol.

Adding 2 stroke oil to fuel - Interesting reading!!

Now here is one to think about folks and BTW I got this from another forum but have a read please.

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%.


and more :-
You may all know that Mercedes Benz have conducted in 2007 a long distance reliability test with a number of Mercedes E-Class 320 cdi from Paris to Beijing. Due to the fact that the diesel quality in East European Countries, Russia and China does not meet the DIN requirements, and Mercedes did not want to take the risk of their engines to flopp due to lousy fuel, the total tour has been accompanied by diesel tanks to re-fuel the E-Class cdi's. Selected members of the Mercedes clientele could apply to participate in selected parts of this test-tour, and advocats and notaries had to certify the correctness of this long term reliability test.
Although Mercedes does not like it published or made public, it is a fact that the diesel-fuel used for this test did contain 2-stroke oil to grease the high pressure pump components and to keep the engines clean during this marathon.
Why our car manufacturers do not officially allow the homoeophatic addition of 2-stroke oil to the diesel fuel has many reasons, mostly of legal nature. Besides this, which car manufacturer has any interest in excessive reliability of their engines? Their repair shops will have great problems.
Meanwhile the "2-stroke-oil to diesel" issue has attracted the interest of a number of Universities in Germany, as this 2-stroke oil has shown to have amazing poperties if added in a small dosis to diesel fuel (1:200), especially the positive impact on air pollution, reduced fuel consumption and improved long term reliability of the diesel engine. The pro and con discussions will go on for a while. But as soon as an accademic report has been published by one of our Universities, this will change very fast.
By the way: all car manufacturers reject the addition of any fuel "additive" in their cars, and warn that guarantee MAY be affected. Nobody says, that guarantee WILL be rejected. 2-stroke oil in its properties is not an additive, as you add oil to oil if you "dope" you fuel with a dosis of 2-stroke oil. The dosis of 2-stroke oil in your diesel-fuel is very difficult to analyse, as every (chemical) analysis has the main function to identify substances which are harmful. But 2-stroke oil has proven not to be harmful at all, on the contrary!
Personally, I use 2-stroke oil now for many years in all of my diesel cars (my present business car is a Mercedes 320 cdi DPF Automatic). And I never had any problems whatsoever.

Signbloke here again:

I have been adding 100mm of Penrite 2stroke oil to our Golf 1.9tdi on every tank (50litre tank) for the past 6mths, no effect and does run quieter at idle but each to there own on this one and it cannot hurt as far as I am concerned, you just don't know what sort of fuel mixes we all are putting into our cars now days and any extra lubrication has to be a good thing....

BTW it also did make a big difference in my fathers 4.2litre Nissan Patrol, running very quiet and stopped the loud ticking at idle (130,000kms)....

Copied from the Nissan Patrol 4x4 forum and here is the whole thread link if you want to read it all 2 stroke oil in your diesel fuel - Patrol 4x4 - Nissan Patrol Forum

No problems Transporter!!

New to the forum and I tried to do a search first but was unsuccessful in finding anything but thought there would be something on here about 2-stroke oils....I'm out of warranty now but it runs lovely and we plan on keeping it for the next 10 yrs, not one to swap vehicles often, I've had my work Hilux 15 yrs now, sure its slow & reliable but looking soon to get a dualcab transporter....Nice!!

Love the site BTW - heaps of info.

Cheers

Now here is one to think about folks and BTW I got this from another forum but have a read please.

Fantastic post and a great thread revival for those of us who weren't around for the original thread.
I knew I kept that Amsoil around for some reason after I stopped racing

And here is the original source of Signbloke's info - the OP certainly seems well sourced for her information and a someone has posted that they will soon post some comparison pics of disassembled CR HPFPs that have been run with and without 2-stroke oil .

Pretty much everyone who tried good quality 2-stroke oil at 200:1 reports lower noise if nothing else (including those who have also used diesel additives) so it seems to be good for the injectors and pumps. Too bad I just filled up else my 1.9 PD would be a good test for noise reduction.

I bought a bottle of Castrol 2T yesterday and I intend using it. My Golf doesn't get used much, last fill up was a couple of weeks ago, time before was 4 months ago.

While it is best to put the oil in THEN fill up, I didn't see anything that said you can't add the 2T oil AFTER fill up.

Any comments/advice?

[twincab]

You add oil first so the fuel going into the tank mixers with the oil. If you add it after there is a good chance it won't mix properly.

cheers Pete

[kaanage]

Getting the 2-stroke oil to mix well would be my concern with adding AFTER filling. While non-vegetable (eg castor) 2-stroke oil is fully miscible with diesel, it could take a long time for the 2-stroke oil to mix well without agitation or stirring, especially if the 2-stroke oil has a higher specific gravity than the diesel (which I think is likely).

What I'm thinking of doing is syphoning out about 5l (or more if I can find a larger fuel container) from my freshly filled tank and mixing 225 ml of 2-stroke oil with that and then pouring the resulting mix back into my tank.

Best to add the 2T first, then fill up the tank.

In your case I would also be worried about algae in the tank, and I would be adding a treatment aimed at killing any growth.

Cleanpower or FTC decarboniser from Costeffective.com.au would be my choice for that.

[WEDEL.1]

Thanks for the quick replies.

Twincab - I'll be parient & wait until the next fill up in a few weeks when we head over to WA for the Bug-In.

Gerhand - I'll buy a bottle of something to make sure I don't have any unwanted passengers ASAP.

But the thread that linked to explicitly stated that using very low ash 2 stroke oil would not be detrimental to the DPF since these oils are specifically designed to burn very cleanly with lower ash content than most diesel stock.

I know that the 2 stroke oils we used, after we switched to using unleaded fuels, left the pistons and cylinder heads so clean that there was basically no way to read the burn patterns and you had to tune using EGTs and detonation counters.
