2 Stroke in Diesel. Test car - BMW 320d.
Discussion
I was used to the silky smooth petrol six in my Z4 before swapping it for a BMW 320d. This was a 'sensible' (eco) choice, but to keep a bit of a grin on my face the car is mapped, has a straight through exhaust, and filters.
As 4-pot diesels go it's pretty good, but I obviously found it to be rough and lumpy in comparison to the straight 6. How I miss it!
Anyway, I've been reading in a few forums about the benefits of adding 2-stroke mineral oil (low ash) to your fuel tank before filling the car with diesel. I couldn't find any negatives or dangers in doing so, only positive feedback and some pretty convincing evidence.
It's important that the oil is Jaso FB spec compliant, low ash, and not fully synthetic - because this does not burn well.
This 2-stroke/diesel blend apparently brings the following benefits.
1. 2-stoke burns better and more cleanly than diesel. This means more complete combustion of your diesel fuel.
2. Helps to initially clean out the engine internals, and keeps them clean.
3. Restores missing lubricants (and more) from low sulphur diesel.
4. The engine runs much more smoothly and is much quieter.
5. Significant reduction in smoke from exhaust (due to better combustion). Applicable for cars with no DPF
6. Keeps the DPF cleaner.
7. Increases the life of the engine, including injectors, fuel pump, etc.
So, I thought I'd give this a go!
Last night, I put 300ml of 2-stroke oil, into my car, before filling up with Shell Fuelsaver Diesel. I then set of on a 125 mile journey home, not expecting much...
However, after a short while I found that the engine was quieter and running much more smoothly! Much less clatter on the outside and definitely quieter in the cabin.
The car seemed to be a little more responsive and pulled better in higher gears, especially at low rpms. I found that I didn't have to change down nearly as much when cruising at low speeds and whilst accelerating.
My car used to let out a little black smoke when I put my foot down, slightly embarrassing! However, now there seems to be none at all! At worst there is a little haze, but nothing more than that.
Based on what I've found so far, I'd definitely recommend giving this a go. I was really sceptical about noticeable results, but it seems to be working a treat!
It's still early days yet, but I'll report back after a couple more tanks with this stuff and update my findings.
You may want to Google compatibility with your specific car. I take no responsibility in people trying this trick for themselves.
I'd be interested to know if anyone else tried this?? With good or bad results?
PS. No derv-head jokes please! I am not one... I'd go back to a petrol 6 anyday!

I suggest you add a disclaimer.
fk. Forget that. (twice in 10 minutes i reply without properly reading what im replying to) Dam
Maybe i could insert soomething about a 335d and all will be forgotten?
Imagine what it would do in a 335d! (better)
(..Shut up ben, just shut up.)

what year is the "test car" ?
Who told you this? And why not out of interest?what year is the "test car" ?
I've only heard good things, on new and old cars. Including Audi's, VW's, BMW's, Landies, etc.
My car is 2006.

Funnily enough you'll probably find the TDCI Landie is more sensitive than the beemer! the Ford TDCI system is notoriously complicated and sensitive.
Oh darn. Surely a Transit engine (which it basically is!) can't be complex?! It sounds about as sophisticated as a Millwall fan.80sboy said:

my advice was from a intendant Mechanic..he said it was ok with the older basic stuff (like the ancient 1.9 VAG units and the old French Diesels etc..etc.) but a big NO on any newer cars.

Also an indi mechanic, or any mechanic for that matter is unlikely to be an expert on the subject, unless they have some specific reason to be an expert that is. But general mechanics certainly won't cover such things.

But without reason that advice is pretty pointless. You need to know why it can or can't be used.

do you have a standing argument with everyone you ask a question of in real life?Also an indi mechanic, or any mechanic for that matter is unlikely to be an expert on the subject, unless they have some specific reason to be an expert that is. But general mechanics certainly won't cover such things.
I asked the mechanic if it was a good idea or not...his reply is pretty much word for word how I typed it.
should I have pestered him some more you think?
his reply was good enough for me...I had no reason to call him a Liar!

good luck then...my volvo D5 is 2002 and I was advised strongly against it.

I'd be interested to know his reasoning behind that. This is the first negative I've heard about doing this. my advice was from a intendant Mechanic..he said it was ok with the older basic stuff (like the ancient 1.9 VAG units and the old French Diesels etc..etc.) but a big NO on any newer cars.
In fact, I read that behind closed doors many manufacturers have tested this themselves with very positive results. I'll see if I can dig it out on Google sometime.

Tbh 300 is right , since when a mechanics word is gospel ? I find some mechanics incompetent at best especially Indy ones I asked the mechanic if it was a good idea or not...his reply is pretty much word for word how I typed it.onethebond@googlemail.com
