#1197 of 2551 Model years are not the issue... by jrct9454

The current generation body of both the Jetta and Golf will probably continue in the North American market well into calendar year 2005. Thus, the first "2005 models" are certain to be the current cars, just as you see them today as '04 models.
 
Sometime in the calendar year 2005, the new generation of Jetta will be introduced into this market. Whether VWOA chooses to call them '05s or '06s will depend on timing and marketing. However, it is virtually certain that the diesel engines in these cars will be the SAME as the current ones. [There will be new gasoline engine choices, but that's not the focus here.]
 
The next change to the ENGINES in the TDIs probably won't occur until model year 2007, when the availability nationwide of low-sulfur diesel fuel will allow VW [and Mercedes and perhaps Audi and BMW] to give us their latest technology in diesel. For the VWs, that should mean we will get the 16-valve heads here, finally, that are currently available in the EU. This in turn should mean lower emissions, better running, and a few more hp. Not a revolution, and depending on your needs, perhaps not worth waiting for.
 
In any case, the new body style for the Jetta will not signal a new engine right away for the TDI...that comes later, as the fuel problem in this country finally gets solved.

Considering major cities already have low sulfur fuel for their public transportation, I don't think it will take a whole year for widespread availability. The rule says it has to be available in 2006, not phased in.
 
In other words, the stuff they are pumping now will disappear (with the exception of use in off road equipment, such as farming). Anything on or near a highway MUST be low sulfur.
 
I think this is why Chrysler is waiting until mid 2006 to launch the SMART brand (which features diesel engines).
 
I'm just hoping and praying they can meet the green states' emission rules soon

Which states are green states? You mean the CARB emissions states! TDI will have 50 states availability in 2006.

We are talking ELSD here. (Extremely Low Sulpher Diesel)
The LSD is allready available for all road fuels.
The HIGH sulpher diesel is also available, but is dyed a bright pink to indicate it is ILLEGAL to use on the road. It is intended for Farm equipment and other NON road-going vehicles.
 
In farm communities, there are 'gas stations' that have a pump that delivers the pink stuff. The price is about $1.65 gallon because it does not have road-tax applied to the price. The TDI has a CLEAR section in the fuel line under the hood that can be used by law-enforcment to inspect for pink fuel. Dont get caught with this pink stuff in your tank!

#1201 of 2551 Low-Sulfur Diesel... by jrct9454

Jun 11, 2004 (2:40 pm)

...is indeed going to be "phased in" and is not required nationwide until very near the end of calendar year '06. Of course, it will be available [already is in lots of places] sooner, perhaps even in MOST of the country sometime before then...BUT...both VW and MB have stated they want it guaranteed nationwide before they switch to the latest EU diesel technology for this market. I still maintain that means nothing new for our TDIs until late 2006, when the '07 models will be appearing. Would love to be wrong...
 
And there is still an awful lot of crud out there being sold as diesel - low cetane, high sulfur, and barely useable in modern auto diesels. Just go to the TDI Club website and read some of the laments - if low-sulfur, high-cetane fuel were easy to find, there would be a lot of currently unhappy Pumpe-Duse owners who could relax and start enjoying their cars. This is a real issue with the '04 PD engines.

#1202 of 2551 Actually it is ULSD by moparbad

Jun 11, 2004 (5:03 pm)

Ultra Low Sulfur Diesel is the complete name of the 15 ppm or less diesel fuel to be mandated in 2006.
 
Quote EPA - U.S. Environmental Protection Agency (EPA) rules will require that new diesel engines meet lower emission levels beginning in 2007 and will require ultra-low sulfur fuels for all on-road engines beginning in 2006. -end

Low sulfer thing is going to be another reason for them to jack up the price. Now, in PA, diesel is going around $1.679, I wonder it will be in the same price (of course + inflation)...

#1204 of 2551 Of course it will cost more... by jrct9454

Jun 12, 2004 (6:45 am)

...that should go without saying. Who wants to bet on the price of fuel 2 years from now? Not me. And in any case, diesel on the West Coast is already up and over $2 a gallon in many places - still cheaper than gasoline almost everywhere.

#1205 of 2551 Good diesel by madijo

How can you tell what quality diesel you are getting at the pump? I have looked around but not seen anything with a rating on the pump.

There's the rub:) Most states have no rating system for diesel, just that it must be at least 45 cetane (i believe). Based on my experience, good diesel is clear where most diesel is a brownish/green color or sometimes looks like mountain dew. The other way to tell is by how your car is running. Higher cetane fuel will quiet the engine down and provide more performance. I also see NO smoke running a premium diesel, even on a cold startup. I run BP/Amoco Diesel Supreme whenever possible (reported to be 50 cetane and 30ppm sulphur). It's hard to find and sometimes BP pumps say "supreme" but have regular #2. Some BP/Amocos don't even carry BP #2 (private franchises are only required to purchase XX amount of BP refined fuel). If you can actually buy BP #2, it's not bad. If I jump from typical truckstop crud to BP Supreme, the difference is extremely obvious. The car quiets down noticably before you get out of the parking lot.
