For those that add 2-stroke oil..

[Rock Trol]

2 stroke is good. There is even an injector company who has done testing with injectors. Even showing the results to denso showing the effect.

Nothing wrong with it at 200:1.

Guess you shouldnt run engine oil either due to trace metals in it that might clog up your engine galleries.....

Do you know if they where Di or CR injectors tested by the injector company? Sasol's article is specifically about CR injectors and pumps. They may have extrapolated results to the non CR injectors but that does not mean that it is harmful in their case.

Common rail. The injector used was one from a d4d hilux. 3 tests were done. 1 with nothing, 1 with 2 stroke, and one with a low friction hardened coating.

I've been using it for a while in my crd I don't see any fuel improvement but it runs quieter and smoother and IMO can be felt while accelerating, I'll keep using it

[Rock Trol]

So at least it's not harmful to use which is the important thing.

Interesting. I use it on long trips and i find it quitens the motor straight away, it's a little more responsive and on the highway i can save as much as 1ltr per 100km and this is proven over many a times. I disagree that it doesn't help lubricity.
As mentioned this is test has been conducted by a fuel company which lets face it they're not going to tell you to keep adding it if it's taking money out of their pockets. Hopefully as time goes by there will be some more tests conducted.

Cheers for the share

Rather interesting. I tried the 2 stroke in my 4.2TDi and found no difference in performance, economy or noise so have about 7 litres of oil for my wiper snippers.
I used Chemtech additive on last fill and performance has improved but that might also be a result of a good hard run over on Fraser's loose sand for long weekend which has cleaned out a bit of crap built up over recent months of short trips.
Don't think any of these products are VALUE for money if you have good diesel to start with and good filters.

would you run 2 stroke in a 8V92TTOB

It is indeed interesting. With my identical motor I noticed the difference (quieter & smoother) within the first kilometre or two after putting it in. Motor was stock & had around 160,000 on it then. Since then the exhaust, dyno & EGT has smoothed things a little more. I wonder if I would have noticed as much difference if I had tried the the 2t for the first time after the exhaust & tune?

Yep me too cuppa, I noticed it was quieter almost immediately too but no improvement in fuel economy like a lot report. I think us with the 4.2 with mechanical fuel pumps will notice the noise reduction but not the later ones.

Humm, think me have a go at this and see what diff it makes.
I was thinking injectors were starting to get a little suss, report back soon.
