Your most sensible post so far, nothing like copy and paste is there? All completely irrelevant to the op of course but don't let that stop you...

WHAT????? still reading my posts's ??? You really are a glutton for punishment...I'm beginning to think that you are becoming fixated with me..you can get help for that you know. My most sensible post so far? Really?? have you taken the time to read all of my post's? Thanks for the compliment, but then you go and spoil it all with the derogatory ...copy / paste criticism.
For your info ( in case that you are still reading this ) I bought a 2003 A6-C5, and did a bit of research on the engines...the above result is what you see,,,actually that same research came up with the 2T Oil as a possible solution for my limp home problem, ( it worked ) and the Injector Loom / harness problem being the cause of the mis-firing, which also worked

The thing with 2t oil is that unlike 4t engines the exhaust has to exit via a hole in the side of the cylinder, funnily enough known as the exhaust port.
Over time the hot gases and carbon build up in the port causing it to change shape which has the effect in a two stroke of changing the engine timing due to the pistons ability to open and close the port at various different heights.
To combat this phenomenon a lot of 2t oils are designed have an anti coking/fouling property to stop this occurence, using a little 2t oil in a diesel with an overboost problem due to fouled turbo vanes not being able to move can help with the lubing and decoking of the vanes.
Calling someone out for using 2t oil because you don't understand the properties of 2t oil is not the answer.
In short many 2t oils are very good at removing oil deposits from diesel engines because they are designed to do that exact job in a different type of engine.

Thank you, CJ, thats as good an explanation as I have heard for describing the beneficial effects of using 2T oil in a diesel engine..It has certainly worked for me, and I'm not the only one.:D:D:D

CJhaughey · 23-09-2019 02:38PM

I used to use it in a Honda Accord 2.2 ICTDI and a Landcruiser 1KZ-TE before that no issues and the Landcruiser is still working fine at 350k miles so I doubt it is harmful, the only thing that is stopping me using it in my IDTEC is the DPF. but that might not be an issue for much longer.

Yes the DPF is what is stopping me from using it in my present car, MB W212 2.1, but I know some one who is,,and has been for a long time, with high mileage. But I'll wait a bit..car is running fine now in any case. If you find out that it works in DPF engines, please let me know, Ok? Thank's.
The Landcruiser 1KZ-TE was / is some car....was my introduction to LC'c back in 1993.. I remember pulling an Artic, with a full loaded 40' trailer to get it started..only took a few metres of a pull to get it going. I drove them through rivers too, when the breather was needed to supply air to the engine.... Best all round 4 x 4 in the world INMO. Would trust my Life in one.

Not the cheapo 2T oil recommended by Tommy Cooper the comedian it'll coke her up worse than a steam locos boiler..

The Op doesn't have a misfiring problem, cheap strimmer oil won't fix hardened cables under the rocker cover.

A landcruiser? Why bother on one of the crudest diesels going, not that there's anything wrong with them but 2T oil won't make a blind bit of difference to it's longevity.

Lads my diesel has started making a loud wumming noise after reading this thread in the car.

Just goes

Wum

Over and over again.
Should I ignore it?

It's all very mysterious.

I don't know really understand it myself TBH...just amazing the reaction the mere mention of 2T oil can trigger in some people,,,guess we will have to wait for Boco55 to finish unloading his angst( or whatever is bugging him...) :cool::cool::cool:

Mighty stuff !!! The effect's are just unbelievable. Which one do you prefer? The chape stuff, or Husqvarna? or maybe Stihl 2T?

I hope it doesn't block up the exhaust port!!

No I guess it wont fix the harness problem.....especially since it goes in the fuel tank.....not in the engine oil.:rolleyes::rolleyes::rolleyes:

I dont think he was suggesting that it did.

Not true...been using it for years, same as CJ Haughey...no problem. All 2T oil has to do the same job. I buy mine in the local Farmers co-op.:D:D:D

Yeah, but he didn't say it assuming it went into the engine oil. It was just stating it's unrelated and wont fix it.

Question of interpretation so, and my interpretation of "cheap strimmer oil won't fix hardened cables under the rocker cover" is exactly what he said...I have already explained how I fixed the mis-firing in my 1.9.cheap.

Could be a very easy fix, and without any 2-stroke or Mr. Muscle... :pac:

Yes, sound's good. RossTec is very good for any VAG problem's. Worth checking out at any rate.

Well, the boost sensor has been replaced and it's only on a short length of cable which if it was damaged would be easily spotted. Could be a dodgy earth but I don't think so as there would be other symptoms too.
