I have been using the performance formula all season. It will clean, lube, and increase fuel MPG. This is the only additive that VW says to use and it is made by people that design fuel injection pumps. Just use the correct amount every fill up. Highly recommend doing this with the ultra low sulfur diesel fuel.
well i work at a diesel shop. and all we sell is the performance formula. (Blue Bottle) thats what we recommend all year long even over the winter formula. the winter formula is the same thing with out the cetane. the poor points are exactly the same between the two.

Actually, I believe Stanadyne performance formula is the only additive officially approved by VW. It has a VW part number. I believe my 2006 BEW Jetta had this info in the owners manual.
IDparts agrees: http://www.idparts.com/catalog/prod...d=393&osCsid=0426500133530981efb8751295b52196

Yes, I've heard that they do approve Standadyne, and that's a big part of why I use it, although I have never seen written proof of that from VW themselves.

Stanadyne was "approved" by VW only for the older models, to make up for lost lubricity when LSD changed to ULSD. This is not because Stanadyne is the best product out there; it is simply because VW and Stanadyne had a mutually beneficial agreement in place.
The partnership between VW and Stanadyne has since dissolved; and at this point dealerships stock it only to support those older model TDIs that still wish to use it.
There is no recommended additive for CR TDIs; though they are not advised against either. New models make no mention whatsoever about additives in the owner's manual.

One of the better additives I've used.

I was told by my dealer that we're allowed to use Stanadyne, but they didn't say anything about it being approved. I mentioned that I use Optilube and they said it was ok BUT if it caused any issues with my engine my warranty would be voided.
So...not trying to scare you if you DO have a warranty, but keep that in mind if you use anything other then Stanadyne while you're under warranty.

The Bentley manual states that VW recommends he use of Stanadyne, and I think there was even a tech bulletin on using it.
People on here have mentioned that VW doesn't recommend any additive any more. Stopped a few years ago.
People have also comments on here that: "if VW doesn't recommend Stanadyne, then why is it in their parts department?"

Did they also tell you not to change your own oil? What they say is SELF-Serving, in one ear and out the other. If the dealer was Alexandria, VW on Glebe road don't listen to them. I bought my first car from there in 1987. They are not to be trusted.

The reason on the cr engin's is the fuel filter are a lot better and won't allow your product to pass throw.

We have not data concerning effectiveness of these additives and HPFP blow ups, I wish I could find some real data. In the mean time I use PS gray bottle since I'm in FL. My JSW 09 has been fine so far and I have idea if it's because of using an additive ,but I will keep uising it till a problem.
VW wouldn't say that an owner needs to use an additive,because it would admit a flaw in the system. The average person would have no interest in dealing with some mumbo jumbo additives. Just saying.

OK I think I can we are running filter that can stop water and dirt down to a very fine micron so how will a They's additives help I'm not telling you not to run them I just don't think you are getting what you think you are. But to each there own right in that case why not run atf it's got lots of detergent and oil for lube.

Commercial main stream fuel additives pass right through the factory fuel filter on CR engines and every other engine, AFAIK.
Source (again) for your claims?

They haven't.
The OEM fuel filter on CR TDIs is a 13 micron filter; it is not a "very fine" filter in any way at all...
Additives are already in the fuel you pump into your tank, they are what make ULSD safe enough to run in modern diesels to begin with; how in the world could a fuel filter possibly filter out additives...?

Maybe they need better filters I know the gm one I run on the trucks are 4 micron which is pretty tight but 13 well I'm surprised at but like I said run what ever you want in they end it your car and you should make the best decision for your car.

Well...they can't.
I'm new to diesel fuel, but I know that the additives that the refineries put in gasoline only are sufficient for thirty days. After that fuel stabilizer has to be added.
Is diesel fuel the same? I know farmers add diesel fuel stabilizer to their large storage tanks of diesel fuel. And the farmers that I know don't spend a penny that they don't have too.
Heck, my first tank of diesel fuel looks like it's going to last me at least a month.
