Basically he's saying that the decision to use fuel additives is a "religious" one; either you believe in them or you don't. Personally I'm an additive atheist so I won't use them.

For those of you who disbelieve the benefit of using a diesel additive. Read your owners-manual to find out the RECOMMENDED cetane for your engine.. .then read the pump where you get your fuel from. let us know what you discover.
I concur that using more cetane than recommend does not give you much in return.... but using LESS cetane gives you lower MPG and noisier engine.
The added lubricity is a bonus ... I assume all of you are aware of HPPF (High Pressure Fuel Pump) failures that some folks have reported.

well I will have to research this additive thing a bit more. I was just surprised to read a post that made it sound like it was vital and since I did not do it I was a loser or had no idea what I was doing. if my car was 8-12 yeas old and I was doing all I could to keep the thing going, I would look at fuel additives, but I am not sure it would be a good thing for me to add to my 2010 VW Jetta TDI sportwagon. If you have an article I could read that proves how ignorant I am I old like to red it. An article in favor of a diesel fuel additive.

I tried to find any such articles on additives. My nephew rebuilds injectors for diesel engines and claims the diesel we get in CA in inferior. However Bosch says this about using additives:
Many additives for diesel fuel are on the market and when added to a fuel tank they will supposedly deliver a number of positive effects. These include cleaning the fuel injection system, improving combustion and enhancing performance. It is unclear which, if any of the additives, actually do what is promised.
What is clear is that using such additives does present some risks as the composition of these additives is generally not listed on the packaging and so you donít know what is being added to the fuel system.
Reactions, some of which may not be desirable or described by the maker of the additive, can occur when these treatments come into contact with other lubricants such as engine oil or with engine components.
Furthermore different diesel fuels have different additives and oil companies do not disclose what these are, so there a likelihood of incompatibility.
Bosch does not recommend or approve of any diesel additives and the use of these may affect warranty.
It looks like this link may not be from Bosch USA. So I would not consider it the final word. I just could not find where VW or Bosch recommended using additives. So the debate will continue.

It is not simple as saying "Made in XXXX". In today's world economy, it is way to simplistic to suggest that an automoble is "MADE" in any single country.
If you READ the window-sticker, you will see that the engine is "assembled" in one country, the Xmission - another country... and the entire assembly - yet another country.
Do not forget that several BMWs are 'assembled' in USA... but only sold outside USA. (go figure)

News to me; as far as I know, pretty much every model built in South Carolina is also sold here in the States.
