Very interesting subject and will follow this with interest. I have very little technical knowledge of this subject myself and was just wondering if adding 2 stroke oil would ever effect your warranty. My car is under warranty until June 2013.

Nearly all the advocates of adding two-stroke to diesel say that if your car has a DPF then you should not do it. If your car is still in warranty I'd guess it does have a DPF, a diesel particulate filter to remove part-burned fuel particles ("soot", although most of it is microparticles and not visible as smoke).

The warranty question is difficult, as I doubt it would be possible for the supplier to tell if you'd been using two-stroke oil or not. Unless it was Castrol R which has a very characteristic smell

I'm with Muttley on this one, I think your car is far to new to be doing this, me and the other guy have much older type tdi engines.

I agree with muttly also I'd stay away with ur engine having the much problem matic dpf engine my pd engine is a lot older in design and was designed back in the days when our diesel was a lot better than it is today.

Right the last couple of times I've put fuel in I haven't put any 2 stroke in. So far I've noticed the engine is that little bit noisier again but I can't decide if the car has a little bit more of an edge to the power or not. Need to keep testing.

Well I have only done the one tank full with oil and just filled up yesterday with no oil so not really tested again with normal fuel only yet will keep u posted
