I think you must have the all time mpg/mph best numbers on this forum.
Not to dump sludge on your 03 Jetta Speedster, but consider what Honda's been busy at out on the race track.
"U.K., – Honda’s new Accord 2.2 i-CTDi Sport has this week set no fewer than 19 world speed records and achieved 3.07 litres / 100 km (92 mpg) fuel economy to boot. British racing driver Robin Liddell and freelance journalist Iain Robertson were part of the European record-setting team."
VW has this Diesel Family Sedan market all to themselves (for now) and I think if they start trying to fix what ain't broke, they will lose all they have gained since the mid 2000's with TDI,s...i.e. (rumor alert) requiring the 2010 Jettas to fill up on Urea every 7000 miles ($200)

..."Not to dump sludge on your 03 Jetta Speedster"..
No worries here ! It has been tdi GURU inspected (during the 100,000 miles TB/WP change interval) !
1. No intake manifold or EGR "sludge," despite using LSD (500 to 140 ppm) most of its mileage at that point (75% of 100,000 miles) . Thanks to the EPA and CA carbs etc. This 03 TDI was designed to run on ULSD (15 ppm to 5 ppm).
2. Clean as a whistle camshaft (original tool markings) and innards with 25,000 miles oil and oil filter changes !! I am a belt and suspenders kind of guy, as I do not do 30,000 mile OCI's.
My take has advocated MORE oems' putting more and varied diesels models on the US market ! I only cycle back to VW, because this is a VW diesel thread.
I actually would like to put the Honda Accord 2.2 i CTDi through its paces. to see so called "real world" mpg.

The Honda Accord had me excited about Honda once again after writing them off 30 years ago as Jap Junk. The whole bit about the auto transmission version failing the emissions test smells to me. The powers know that a Honda diesel Accord getting close to 50 MPG would be a killer. Money talks even to Honda executives. The people that control CARB and the EPA DO NOT WANT A LOT OF DIESEL CHOICES. The VW TDI is just tossing a little steak at the faithful few diesel lovers. Myself being one of them.

I read in one piece about the Honda Diesel speed tests, that the drivers of the vehicles got the 92 mpg figure when they drove them back to the city...
If that was the case, I wonder just how modified they were by the factory for the Speed Tests, and how much of that 92 mpg number is from the 'Outer Limits'.
In any case it's a shame that some sort of Diesel Conspiracy does seem to exist in the U.S.
Everywhere you look people are knocking them using stale data from the 8o's and just downright stupid remarks.
They are even usuing the oldest BS in the book to try and keep a lid on the subject, implying that diesel cars are somehow, "Un-American" in the 'comments' on published Jetta TDI tests in magazines and internet articles.

Jun 28, 2009 (5:58 pm)
I just got rid of the cargo box (Thule) on my Tdi Wagon. It takes 4 people (depending on size) to put it on and off. If you move it forward enough, it clears rear hatch. It's never too forward. I would go with Thule rather than Yakima (but that is my preference - I always had the largest Thule box on my cars). You have to remove the antenna though... But the wagon does not look right with the huge Thule box on top!
Then I have tried Mont Blanc cargo tray/platform and got rid of that one as well (too noisy when driving with open moon roof and too small to load anything on it.
I think I am going to try now Westin aluminum cargo tray - the large size.
If that does not work, I have a trailer hitch now installed and I will try some of the platforms in the rear. It's an on going project now. Haven't found the solution yet.

OK, I found the item and here it is. Now as I re-read it, it is even more depressing than before. Seems that everything about the Honda diesel speed records was on the up and up......................
"Amongst the speed records set, which were all achieved in Production Car Class B (2000 – 2500 cc), were 133.04 mph (1 mile flying start), 84.25 mph (1 mile standing start) and an average speed of 130.38 mph over a 24-hour endurance period. These records were all set at Papenburg high-speed oval test track in north-west Germany on 1 and 2 May, and are all subject to FIA ratification.
Two production cars, randomly selected by FIA officials, were used to undertake the speed records, and apart from the fitting of roll-cages, racing harnesses and radio equipment for track-to-pits communication, no other modifications were made to the cars.
Following the speed record attempts, the same two cars were then driven 419 miles from Papenburg test track to Wiesbaden, near Frankfurt in order to complete the fuel economy run. The route comprised of a mixture of motorway and non-motorway driving, during which one of the Accords achieved a staggering 92 imperial mpg (US mpg=~76.6) average.
The project, whose aim was to demonstrate the performance and economy of the Accord i-CTDi, was a joint production between Honda, the FIA and Italian-based JAS Motorsport, who managed fuelling and pit-stops.
Honda UK’s driver in the speed record attempt, Robin Liddell, who has previously raced at Le Mans 24-hours, as well as the American Le Mans Series and the BRDC British GT championship, commented: "The car’s performance is very impressive, demonstrated by the records we’ve achieved. Honda has made real steps forward in styling, ergonomics and interior design with the new Accord Diesel and now has a package that can take on the best cars in its class."
Too bad we won't get a chance to drive one.

You may be right there but all it needs is to tax the gas the way they tax it in EU and give a break on diesel tax and the public would go for it.
In many EU countries some people now mix diesel with cooking oil half and half to save money. EU is considering clamping down on this "tax evasion" - they may tax McDonalds and other fast foods that sell used oil through back doors and people are mixing it with diesel (my friend from UK that works for Aston Martin and drives a Subaru Forester diesel there is telling me....).
Problem with hybrids is that technology is now already old and aging. There hasn't been any new technology introduced in the past 10 years, since hybrids were introduced. Another argument is that most cells (if not all) come from China - so instead of being dependent on Middle East oil we will be dependent on Red Chinese... seems like an average American would rather be dependent on China than Middle East, right?

VW gets a very respectable 24 mpg on its gasser Jetta's. The like model (diesel 09 Jetta TDI, DSG) on the other hand is almost literally vilified for getting 38 mpg or 58% BETTER fuel mileage !!!!!?????
If you use the EPA average mpg for the 09 Jetta gasser, why not use the same criteria when comparing to the 09 Jetta TDI? The EPA avg mpg for the TDI is 33mpg, not 38mpg. Where does the 38mpg come from. Is it some kind of official statistic or is it the result of several TDI affectionados. Some TDI owners get substantially better than the EPA avg and I believe there are probably some gasser Jetta owners that get better than the EPA avg as well. I'm not bashing TDIs by any means but I just like to see statements that appear as fact not be backed by a few people that either are hypermilers or close to it. I see one guy on the Camry forum that is consistenty getting 40mpg out of a reg gasser I4 Camry. That is not the norm by any means and is questionable in my opinion.
The EPA website has the Jetta gasser getting a little better than the stated avg with 2 drivers reporting. The Jetta TDI has an average of 40mpg with 21 drivers reporting. While that sounds great and I have no reason to doubt them, it is still just 21 drivers out of thousands which may be as small a sample as 1% or less.

I just got a new Jetta TDI sedan with DSG. Since this is my first diesel I want to break it in right. How should I drive it over the next 1000 miles to get the best results?

Not an issue, then use 33/34 mpg. It is STILL 42% better !!!! ???
I get an average of 42/43 (79%) and I am NO hyper miler. Indeed the thing will not be broken in for least another 3,000 miles, with 10,000 to 60,000 miles "full" break in. So there is an expectation the mpg will go up from there.
