diesel power service by ndmike88

Anyone use it? Does it really help with the TDI performance? I know it boosts the cetane in the diesel fuel but does it really work? Is it VW approved?

ruking1's link is right on. A no-brainer method is to drive in sport mode for the first 5K. Do not go on any long freeway cruises and do not concern yourself with fuel mileage during the first 5K.

Yes. It is supposed to help with TDI performance. After 125,000 miles, I can tell no difference.
I do use it primarily for:
1. H20 emulsification
2. fuel pump lubricity
 
These are all chemical reasons I can NOT see.
 
3. It does boost the cetane,
 
4. boosts power
 
5. offers high detergency
 
6. better mpg
 
7. cleans injectors and combustion system
 
but I really have to take their word for it.
 
VW's official recommendation: no additves are necessary or required.

I got my Gray DSG TDI jetta from Fitzmall for $20,992. Paided for shipping and was still thousands under what my local dealership could/would do.

Now you have me worried. I don' want to add a rumor onto a rumor, since we don't really know if they will go the urea system route in 2010, but I also find it hard to believe that it is due to fuel economy. I am wondering if it is due to a maintenance problem with the DPF? I know that they delayed the introduction of the 2009 models (or was it 2008?) for several months until they worked out bugs in meeting the U.S. emission requirements, though nobody ever detailed what those were.
 
I was on the verge (or so I thought) of buying a 2009 TDI, but don't want to be orphaned with a long-term maintenance problem. Maybe it is all a bad dream and doesn't really amount to anything.

On www.tdiclub.com there has literally been ZERO defects on the 09 DPF. There are pretty strong recommendations to use low SAPS motor oil. aka (VW specifications 504/507)

There will always be people on either side of the bell curve, but I think you are the exception on the positive side, not the rule, from what I'm reading. Still no complaints about EPA stats on the TDI. I feel confident I could also best the EPA scores.
 
Personally, aside from the gear heads and aficionados, I don't think more than 10% of Americans would buy a diesel even if they guaranteed you 50 mpg $5 a gallon. Why? Because as fuel costs go up, gas engine efficiency, aerodynamic design and weight-saving technology goes up---historically this has always been true at least.
 
so I guess I'm saying that diesel tech is not a solution, but rather an alternative out of many alternatives.
 
for some however, the perfect solution --people like me, who need some cargo capacity, like in a sportwagon, and who drive 20000 miles a year.

Then I would think we are saying the same things, to you agree with my past posts or recent past posts.

yes except perhaps you don't think selling diesel cars in America is going to be the marketing challenge that I think it will be?
 
also maybe you are more lenient toward VWs reputation than most people, who I think are rather wary of the company's past record in certain areas---specifically, electronic glitches and dealer service.
