Who puts 2 stroke oil in their Diesel?

[bigfellascott]

Anyone doing it? I read quite a bit about it being used in diesel powered vehicles to help compensate for the loss of lubricity with the new low sulfur diesel fuel.

[North East]

I've heard of been done without any dramas. Probably want to make sure your diesel if pretty full.

I filled my diesel up with unleaded once. Didn't try and start it, when I realised what I had done and just pushed it straight in the garage and had it drained.....quite embarrassing.

Ah the dreaded petrol in the diesel trick, I reckon I'll get caught out doing it one day!

Lucky you realised. Petrol in a diesel = dead motor

Yep...it one sure way to stuff up a diesel engine it you try and start it.

Sounds like BS to me. Diesel is a light oil & they rely on the engine oil not the fuel to lubricate.

It's for the Injectors and Injector Pump, this new diesel is low sulfate and as such seems to be causing a lot of issues with pumps etc (low lube diesel basically) hence the addition of 2 stroke to the diesel to increase the lube side of it.

Do a google re 2 stroke in diesel fuel and see what ya reckon.

I do in my Nissan td42 and swear by it.. The injector pump makes almost no noise when added at about 200:1

I beleve the extra lubricity the oil gives the fuel will add hundreds of thounds of kms to the injector pumps life, possibly even to the engines life.

There are also claims of a more complete burn therefore cleaner emissions and better economy.

This is one of many articles i found on the net when researching the topic.

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.

There is a lot of old diesel engine injector pumps now showing unusual wear. I have only seen this in large industrial or mid sized marine. Parts of the pump that don't normally wear or wear much have worn out.
A lot of this has been blamed on the Sulfur being removed from diesel fuel.
I try to put 50ml of two stroke oil in before I fuel up. I doesn't happen often though.
Remember though these engines I'm talking about do massive hours. A lot more than your hilux engine. On the flip size the injection pressure keeps getting higher and higher in these newer small diesels.

Just make sure you use a purely mineral based oil NOT synthetic 2 stroke oil.

[bigfellascott]

Yep seen some of that info before, certainly sounds like a good idea to do it hey.

Be warned, i found it to be highly adictive... I just cant get off the stuf.

I buy 5 ltrs when i spot it on special and keep a one litre container that has a clear window and 100 mm marks up the side in the 4x4 with a long pourer from a diff oil container attached for easy pouring.

Yep apparently the synthetic stuff doesn't mix with the diesel very well (tends to separate apparently), hence the mineral based oil requirements - from memory Castrol Activ 2T (Grey Bottle) sounds like it gets a good rap for use in the diesels but I'd imagine any of the 2 stroke mineral based ones would suit.

I've got a Holden Colorado turbo diesel about 3 years old. I always owned diesels. Quite frankly I can't be bothered make up special fuel mixes. I have to use alpine diesel mix in winter because of the cold...had issues with that once too.

My cars have a hard life in the bush.

Yeah I reckon I will try and find a 20l drum of it and decant that into a smaller bottle with a measure setup.

There's nothing to make up really mate, just pour in .5ml per 1 and jobs done, I've been doing it for a while now (Fuel Doctor) and its a simple process, a quick squirt in at each fuel up and done.

[Oldbloke]

Yep l get the injector thing, tney need some lube. Just not convinced. But as I have 2 diesels I will ask someone who should have some info from mercedes.
I recall the fad of pouring upper cylinder lube (oil) into tne tank of cars yrs ago. Per liter it was incredibly expensive and some companies made a fortune. Problem is petrol engines are designed to burn a little oil, just for the purpose of lubricating the upper conpression rings.. So im sceptical. My guess, great marketing. PS . Will report back on what I find out

Yeah .... im using upper cylinder lube in my high performance petrol toy ( highly worked 355 ci Holden ) but dont worry about it with any of my other petrol cars. The idea was to replace the lead that lubricated the valves and upper clynder, also making the fuel more stable to avoid pinging. Propperly reconditioned heads should have ulp friendly valve seats fitted wich means on a standard engine there is no longer a need for additives.

I use Morries upper clynder lube for a few extra resons like coating the carburetor internals, fuel tank with oil to prevent corrosion during its 9 month long sleeps in the shed, lubricate the throttle components as well as its other designed benefits particularly helping to controll pinging,
I felt that a high compression engine with extra stroke, larger valves, shorter piston skirts and thinner rings needed all the help it could get.

Just spoke to my cousin whose a 40 year experience mechanic about the 2 stroke question. He fully agrees with the 200:1 comments.

Also spoke to a mate who farms about 3,000 acres of crop each year, using harvesters etc. He asked me "aren't you city blokes aware of this. Crikey, you need to spend more time out here learning a few things......."

Also, don't buy a new Colorado if your in the market (his advice). Go for the Pajero if your a city 4x4 person.

I just use a small bottle and a large syringe without the needle and squirt it straight in before I fuel up.

Excellent tip Timbo, I will have to get down to the chemist and buy a syringe, that would make the whole process a lot easier I reckon. So how long have you been using 2 stroke in your diesel and what brand do you use?

Well there ya go, there seems to be a lot of good info out there on the 2 stroke in Diesel Fuel (you must use Mineral Based Oil apparently as the Synthetic stuff doesn't mix well with the diesel) so make sure its the correct type.

What's the complaint with the Colorados mate?

People who have access to waste AVTUR (jet fuel) run it in their diesels and add cheapo mineral car engine oil for the added lubricity. AVTUR is also less lubricating than diesel. One guy I knew had a diesel Holden Gemini and added 1lt oil / 20lt AVTUR. Depends on how much lubricity is needed to be added.

"She goes good mate"

Same principle.

Sounds fiddly... just for a 30 ltr top up im adding 150mm of oil to get 200:1, that would be a few syringes full.

Apart from the current recall, rumour (yes, I know.....) has it that this vehicle has a few more issues that because of trying different suppliers, some bits are lasting as long.

Allegedly (great word when you don't really know, but, my source is pretty good), small irritating stuff like bushes wearing out quicker than they should be because a different supplier was used and the published fuel figures aren't that accurate. That's probably not a big deal, but other irritating stuff where, "you might have to drop in before the next service" which doesn't really inspire me. Again, rumours I guess, as they've had decent write ups.

I went Pajero recently as I found they gave a softer ride compared to the Colorado (I've got steel holding me together, so, the height and ride ability means more than anything else - the passenger seat turning into a single bed was cool on the Pajero and funnily enough, with lambs wool covers and some neck rolls works ok).

I think the recall is on 2013 models and onwards. Some fuel systems issues I think.

Mine is a 2012 model and so far no dramas. They are just a renamed D Max. I got the base model ute...single cab. All I've done to it was lift the suspension 2", new Old Man Emu shockers and everything that goes with that. Changed the tyre size as well and put a cabin on it.

So far no problems. Really handy having a double bed in back for comfortable camping.
