Hi everyone.

You may be aware of one of the hottest topics on auto and rv Internet forums at the moment; the concept of adding 2 stroke oil to diesel fuel at the ratio of 1:200. Apparently this improves lubrication of fuel pumps and injectors, makes motors run quieter, helps remove water from the fuel and (the holy grail) improves fuel economy by up to 3%.

Personally, I'm sceptical about these sort of claims. Reminds me of the time when we used to add metho to petrol to remove water from the tank and improve performance. I remember testing this one day by putting some water in a jar, then some petrol and then added the metho and....you guessed it.....nothing mixed together.

However I won't dismiss this idea just yet as I believe there may be some real science behind this. I met a bloke a few years ago who swore by PM Oils fuel additive saying it saved him 2 to 3 l/100k and helped his engine run smoother and quieter. He let me try some to prove the point. First thing I noticed was how thick this stuff was. Not unlike 2 stroke oil. When I started the engine, it did run noticeably quieter and smoother. What amazed me was the dramatic improvement in fuel economy. I definitely saw a 3l/100 improvement in what was previously a totally consistent rate of consumption.

So I suppose anything is possible. But if it came to a choice between putting 2 stroke in the tank or a well regarded fuel additive, I think I know where I'd spend my money. But lets open the discussion and see what we find. Hopefully members on this forum are better informed than others and can sift the truth from the crap.

Seems to be some action and playing here - http://www.patrol4x4.com/forum/showthread.php?t=37562

As a Fitter and working with engines of all sorts it all makes some sense but as to the actual outcomes... That would depend on the state of the motor to start with...

Then again.. A few drops of 2 stroke oil Vs some over the top additive... Go the 2Stroke oil...

Re: 2 Stroke oil as an additive to Diesel fuel

Sounds to good to be true - so it probably isn't. I must admit to being a sceptic on most things. Logic being that if it were true then governments , green groups, 2 stroke oil manufacturers, trucking companies, etc ....etc ... would be pushing it officially. I'm sure it will get mileage on ACA , just after the new cure for the common cold.

I have in fact used 2 stroke oil in my old commodore for years. When I had a boat which used 50:1 mix, any left over fuel was put in the crummydore, rather than use old fuel in the outboard when out in the deep blue yonder. Any problems, - none at all. Didn't even smoke. Any benefit - none that I noticed. Youngest son ran out of fuel recently, (at 2am) so he got a full 50:1 10 litres of mower fuel in a nissan pulsar. Started beautifully and runs like a dream - just like it always does (touch wood).

That said , I hope that it is proven true :mrgreen:

I'd be giving more credence to the trucking companies than the rest of that group. The trucking companies would be doing it if the added costs of the 2-stroke sufficiently reduced the maintenance costs in their fleet. The rest have vested interests or wouldn't basically have a clue.*

* Disclaimer: I don't work for a Green group, 2-Stroke Oil manufacturer or trucking company, so I really don't know if they have a clue or not, I have my suspicions about the green groups and sadly I do know about government ... :cry:

Re: 2 Stroke oil as an additive to Diesel fuel

I have been thinking about trying this two stroke thing but the UK Freel2.com post mention that only a Jaso fc oil should be used with a diesel that has a DPF or diesel particle filter. I have an '05 with 3.0 TD. Does it have a DPF?

Re: 2 Stroke oil as an additive to Diesel fuel

So that we can see how far this idea has progressed, I have found the follwoing sites for those who are interested.
One comment that I would make about the comments of those using 2 stroke is that the Site given on previous posts from UK have detailed and intelligent comments particularly by Yamaha-fan who gives tech details and has foowed and used the idea for many years. Unfortunately, the comments on some of the Oz forums are gungho and ignore cautions given regarding the need for certain standards of oil in modern engines, but each to their own. Even if those following this post don't go down this road, it is interesting from a modification point of view. I really have never thought of modifying the fuel in a diesel! There is also mention that Bio diesel is better is added at 50:1.

No, and I'm reasonably sure the D4D doesn't have one either... maybe someone with a workshop manual handy could confirm this?

Hi Guys,
The 1KDFTV (D4D) is fitted with an Oxidising Catalytic Convertor (2 stage) which is used to reduce exhaust particulates, oxidise CO and convert HC's to CO2 and H2O the unit is fitted after the Turbocharger dump pipe, the units internals are off honeycomb cell construction but not sure if the internals are ceramic or stainless steel, I don't think the unit would take kindly to an over oil/ Carbon rich exhaust gas vapour but stand corrected.

Re: 2 Stroke oil as an additive to Diesel fuel

Thanks Mick and Clifton,
The European posts seem to indicate that if there is a partical filter in place then the JASO FC standard 2t needs to be used as it will be low or no ash and therefore will not clog up things. I would read all the post carefully and try to determine the authoritative ones if possible if I owned a D4D. However, I have the 3.0 TD and i have just got back from a run to Melbourne and so I feel I can comment on this as a trial run.

I filled the tanks with fuel and two stroke with a ration of 200/1. 400ml in the first tank 400mols in the second. The second was added as i got up to 120 total to make sure it was going in the right place. Castol Active 2T, semi synthetic. When returning I did the same but I was alittle more generous with the 2t but not much. It is possible to add double the ratio for a motor with 100,000kms like mine for the first few tank to clean it out, so the Euro site states. Mobil 2t organic. All the oil was JASO FC but I could use JASO FB if I can find a cheap source.

Results:
First fill and trip to Melb.
A slight reduction in noise, no idea if it improved fuel efficiency.

Second fill back from Melb.
A large reduction in noise, no idea if it improved fuel efficiency.

COnclusion. It seems the information regarding noise is correct. I think that the info re improved fuel efficiency could be true but it could also be because of changed driving habits.
One other aspect was increase in reported power. Very subjective.....maybe but certainly no decrease.

Re: 2 Stroke oil as an additive to Diesel fuel

So what's your car manual suggest, to use a 2st. oil or not?

Spend your money on something really useful.

Re: 2 Stroke oil as an additive to Diesel fuel

Interesting response Hornet!

I have used it now for two full tanks and I have found a reduction in engine noise and I am led to believe it is due to the lubrication of the fuel pump and injectors. It makes sense to do that. I am happy and will continue to use it.

I am surprised and interested by the lack of discussion on this forum compared to many others throughout the world which is extensive, detailed and informative. I don't care if people use it or not, each to his/her own. Maybe people are reading the other forums and don't need to comment here.

Re: 2 Stroke oil as an additive to Diesel fuel

I tried it in the 2003 1kzj 3 ltr, did not mention anything to the wife, and after I had done 600k's over a week or so I asked the wife if she noticed anything different in the vehicle. Immediate answer was " the rattles seem to have gone", which I noticed after approx. 20 k's as the oil got mixed through the tanks.
Have used the air cooled 2 stroke oil as stated in one of the forums and use what ever was available at the servo at the refill times for the last 6000klms and no side affects, just a quieter fuel injector pump. Have 145,000 up now and cam belt done next service. Was going to trade up, but have decided to keep the old bugger as it has towed a 2.5 tonne van for just over 100,000k so far and has been the most reliable vehicle I have ever had.

Re: 2 Stroke oil as an additive to Diesel fuel

What's best to use, the normal two stroke oil used in bikes and power tools or the marine two stroke oil?

I believe the marine oil is designed for lower temperature use in water cooled engines and leaves less ash behind when burnt.

Any thoughts?

Re: 2 Stroke oil as an additive to Diesel fuel

With regard to adding 2T to your tank, how do you make sure that you get the correct mix of 200:1 in BOTH tanks.
I've been waiting until the 90l light comes on and then adding 450ml. The engine certainly starts easier and runs smoother and is more quiet.

Hi Foxo,
Fill both tanks to 180ltrs the fuel system will circulate the fuel throughout both tanks, this happens continously.
