Diesel Engines 2 Stroke Oil in Diesel

I did run 2 stroke in my 200tdi. Cant really remember if I noticed any difference or not should probably get some more really.

In my diesel astra cdti I use millers diesel ecomax. My starters abit lazy and it starts better with this. It's also quieter. You notice when you don't put it in. If you cant use 2 stroke in the td5 maybe this will do. £12 a bottle on ebay and last 5-6 thousand miles adding 50 ml to each tank tho you'd use more in the landy as the astra does 46-50 mpg.

Just read through this thread with interest.
l was told by my local LR Specialist not to put two stroke oil in the fuel with a TD5, as it could damage the high pressure fuel system. Anybody have any experience running a TD5 with added two stroke oil?

Not had any experience with TD5s and don't want any either... not telling you to do it but at 200 to 1, I doubt it would do any harm. I wouldn't expect a Land Rover dealer to say anything other than what yours said to you. They are generally against anything not sanctioned by the manufacturer whether it would be of benefit or not. The decision is down to you. I hope somebody on here has done what you are asking and can help you.
 
It won't harm Td5 injectors. I have tried it in tdci puma as well with no negligible effect, those ford injectors don't last anyway so I wouldn't bother long term plus they do run much higher pressures.....more than the Td5 unit injectors. They might foul up with 2stoke added but I can't really say as I haven't carried out long term testing
 
td5 injectors are weird though right? whilst the dwell is controlled electronically, the fuel is delivered and pressurised by direct action of the camshaft. only theory crafting mind you, but if you altered the viscosity of pump deisel it could directly effect the injector performance ?..

at 200/1 dosing ratio your not radically altering the fuel viscosity. Fuel viscosity will vary with temperature too remember.
 
Another "two stroke oil in diesel" thread that's died without any real conclusion.....

Still have conflicting opinions as to whether to use it will have any benefits in my 126,000 mile TD5

My best advice is to try it and see. I ran 5 litres through my 200tdi. It makes a difference. Whether it will prolong the life of the car or not is a different matter.

I haven't used any for years now. I just stick a decent cleaner through it once a year. Which makes it run smoother. I put some in the wife's golf tdi without telling her. A couple of days later she asked if I had done anything to it as it was running well.
 
Thank you.

The main thing is, l was told by a Land Rover specialist that two stroke oil will "damage the high pressure fuel system" in the TD5

Prior to that l had been using it at a ratio of around 200:1 and the engine did seem smoother/quieter in operation.

I doubt it. It's such a small amount in the tank. Can understand why they wouldn't recommend it tho as its not diesel fuel. Some people put atf in the diesel tank aswell. Some even use it to prime new fuel filters. It has lots of cleaning properties in it.
 
I think its documented elsewhere but I add the old EP from my gearbox and diffs to the tank (never old sump oil). I do notice a difference but ran out a few weeks ago (must check when my boxes need a change!) and Im sure the engine is running rougher now since I ran out.
I use a cleaner additive too ( https://amzn.to/2YPLcsC ) as I reckon its cheap insurance.
 
Never did this with my LR as I run a two tank veg oil/derv system; when I switch from veg to derv, the veg oil remaining in the system is diverted back to the derv tank and veg oil and mineral oil don't mix and form a varnish like stuff which would gum up its works.
My Fiesta diesel however definitely ran better with some two stroke oil in the fuel, I stopped running it though because of the cost of 5 litres of the stuff. If I could find some cheap or come up with a viable alternative I would start doing it again.
Edit: Correction: Not done this with my LR since fitting the two tank system...
 
Morning Folks. I began thinking about two stroke in the diesel tank again this week. It has been a while, but it raised its head because my injectors sounded louder than I remember. Could have just been all the windows were open ;)

Anyway, it led me to look around for any new information and I found that this thread had been re-invigorated earlier this year. These articles from Unsealed 4x4 (Oz), makes interesting reading...

Part 1

Part 2

And this is referenced in the above:

A technical study

It also includes references you might be interested in. All of the above are in relation to "modern Diesels", non-common rail diesels so might not apply to pre-TD5 engines. In my view the murky waters of diesel additives just got a little bit murkier...

A good read whilst sat on the bog. Although I can’t guarantee that my 200tdi has ever been ran on a diesel/2stroke mix, I assume it’s been ran with regular diesel during its 205,000 mile life. I think I’ll stick with regular diesel and a regular cleaning additive poured in now and then.

Thanks geobloke 👍

Ham.
