The two stroke oil i am using in my 12ht motor

I personally wouldnt. Not with any common rail i was told. could be wrong though.

"Adding 200:1 is only about a 2% mix well within the toyota specs. "

I believe 200:1 is a one half percent mix.
May I ask where you got these Toyota specs from.

Quite correct. My neck top calculations are not that quick anymore.

I was down at toyota and picked up a pamphlet detailing this toyota spec while I was waiting to pick up my car.

Are you positive about that. I was told never to add any additives to the new common rails fuel system. A 5% bio diesel mix is ok, but not too sur about oil. Was strongly warned to stay away from adding anything to the system.

Hi Serendipity,

How long have you been using the oil mix in your V8 diesel?
When you say its more responsive - can you quantify that in any way?
Also do you put it in every tank full - or for example every second fill?
Thanks for info,
Cheers

This is what was in the pamphlet by toyota. Drop in a have a browse in their show room and look at the new cars. This pamphlet was around the waiting area that people sit when waiting to pick up their cars. It was in one of those pamphlet racks along with sets of other toyota advertising.

As for adding just anything to the fuel on the new common rail diesels - Yes I would be very careful. Some additives are just high octane mixes and will only run your engine hotter until it burns a piston or melts an injector. They will make your car go faster for a while.

The information about 2 stroke oil is on many 4x4 forums throughout the world. It started in the forum on this post

http://www.freel2.com/forum/topic878.html?highlight=oil

After that many other forums have picked it up and many others have contributed their opinions. I only read one person in all the threads who reported a negative comment and he said his fuel lines started to leak at the joints - not sure if this was the oil though. That was from reading scores of forum comments. To a standard the rest said they could not tell any differences to most felt there was improvement.

Best thing is to do a google search on "two stroke oil in diesel" and spend a couple of days reading it.

It is your car, and your car has cost you money, and by no means feel compelled to go along with just any fad that is happening. Certainly your motor will not fly to bits if you do not do this.

Try these forum reads on two stroke oil.

Just my findings.

Is sulphated ash the same as the sulphur people talk of in diesel, ie. Low sulphur Diesel and stuff?

I put the two stroke water cooled outboard oil from penrite, same price for the litre and within 5 fims of putting in the oil About 300mls hilus was running quieter, will be puttting in some more next tank just to make sure.

Sulphated Ash and Sulphur are two very different things.

Sulphur is present in mineral oil and its derived products (eg Distillate) as both organically derived material bound up in mainly ring structured molecules, also as inorganically derived Sulphur both as free Sulphur and sulphides of metallic contaminants. About 0.5% of Crude Oil is Sulphur and its derivates.

Sulphated Ash is a measure of the ash depositing tendency of an oil and indicates the residue on ignition of the oil/fuel mixture.
The higher the Sulphated Ash, the higher the residue left in the combustion chamber and exhaust train.

Barry I think you will find it was MB that was doing research into using 2 stroke as they consider our diesel to not be up to scratch.
All dealers will say this to cover their backsides, but at .5% would be totally undetatable

Barry,
The idea of using 2-Stroke oil in a diesel engine is to replace the fuel system lubrication the move to Ultra Low Sulphur diesel removed.

Very late model diesels, say in the last two years of world production have been designed to handle the loss of lubrication from the Ultra Low Sulphur fuel. Engines built for Low Sulphur or shall we say "Standard" Sulphur aren't designed for the loss of Sulphur as a fuel system lubricant.

It's really the old unleaded versus leaded petrol argument revisited. The lead lubricated the valves, valve guides and valve seats. The loss of lead meant older engines needed for their normal expected life an upper cylinder lubricant such as FlashLube.

The end user expectations of any motor vehicle are somewhat opposed to the expectations of the modern manufacturer. We expect to pay a low price for a vehicle with infinite life whilst the manufacturer expects to pay the lowest price for a vehicle ideally (for the manufacturer) requiring replacement at the end of the warranty period.

For us the end user anything that prolongs the life and maintenance period of expensive fuel pumps has to be a good thing.

I doubt that even the very late model diesels in Australia would be designed to handle ultra low sulphur diesel. ULSD was only introduced in Europe in 2006 and Australia only lowered their sulphur to 10ppm in 2009.

The development of the V8 engine I have would have been up to 10 years ago with prototype production at a guess probably in 2005. The first models were released about March 2007.

Could the designers really have catered for this change in diesel fuel. And if they have how well will it work.

The whole thread from the Freelander site started from someone who had inside knowledge into what Mercedes Benz was doing in their research into designing engines to cope with ULSD. Their most appropriate solution they came up with was to add 2 stroke oil. This was only 3 years ago.

From what I read on the Freelander forum.
