Alas I think you are right. Would have loved to experience the thrill, but it's just not really realistic. The V8 it is. Thank you again everyone for contributing to the knowledge base. I certainly learned a lot.

What is really no fun with my Jetta TDI is that in really cold temps the engine actually cools off in stop and go traffic...to the point where you don't even get heat!! it hasn't really been cold here yet so I've yet to experience it in the V10, though the webasto would likely kick in and prevent this from happening.

Nick,

I had that problem when I was in Grande Prairie last January (-37c, not including wind chill)... It would be up to operating temperature, I stopped to pee on the side of the highway, and when I got back into the vehicle, it nearly lost half it's temperature... Despite the Webasto constantly running.... You'll find it turns on right when the snow flake symbol chimes on the dash... It was definately a heat struggle driving to / back to Calgary. Though, it was reliable as hell, and kept chattering away on all 10 cylinders... The windshield wasn't defrosting at the very top 10-12", where it would be completely frosted, even with defrost on, and cranked to high...

In more normal winter conditions in Calgary (-25ish), it would be fine keeping the temperature consistant. ...That was to me, another dimension of cooold! I can't imagine Siberian's climate, it would certainly shorten the life of any vehicle to be subjected to that for an entire season.

 

[siberian]

By season you mean 10 months of the year, counting 3 days for spring, 1.6 months of summer and 6 days of fall?

As I said, it was a learning curve and there are plenty of diesels running around here as you can imagine. But they're TRUCKS, not expensive toys as fine as they are. I know VW and Porsche come up for winter testing but I don't know whether they ever brought up a V10 here. I suppose they did, but given our climate, the type of fuel we access to etc. I will have to pass.

Again my thanks to all who contributed to my decision and learning

Now if the push is to by 2012 enforce (in the US) ultra low sulphur diesel, this will further reduce the caloric content with the following consequences:

1) You will get less and less mileage per gallon - as can be seen today in the difference between the V6 TDI and the V6

2) The engine will run colder given the above.

As a little side note, I've heard people say they get better performance with 500ppm LSD than with 50ppm ULSD here, but I've never experienced this myself. I just stick to 50ppm because I don't feel like changing the 8.9liters of oil every 7,500km.

But what you're saying regarding the caloric content makes sense. Also with the introduction of VW's FSI technology, the petrol engined cars' fuel consumption has also dropped significantly (they say 15% - 20%, I think) which makes the gap even smaller.

V8 FSI it is then...

It is indeed AndrieK. Again thanx to all who shared their knowledge.

As for caloric input... I still stand on the reduction of BTU's / litre burned... between 500ppm sulfer, to 50 sulfur diesel. Not that much is actually lost as said in previous postings (15%).... It's not a loss of BTU's, it's a loss of lubricity... That is why most Diesel Engine owners are complaining... It's not so much in energy loss, but lubricity of the fuel for the precious fuel system (PD) in our Touaregs... Diesel engines still reign top ranks for transportation, and ovall economic ratings each quarter... Diesel engines are still used significantly for transportation of goods.
Whether on Rail, Ship, or Truck... Diesel engines still are ranked highest for economic reasons (in fuel economy vs a gas engine) and economic reasons because diesel engines still provide the highest bang for the bang for their for their buck... VS a gasoline powered engine... Who the **** uses a Gasoline powered Rail Engine? Or Ship Engine? Diesel fuel has become the target for environmental harm... It's fair that it is being isloated for this reason, but another real-world reason is lubricity for the high-end fuel injection systems that support these low-environmental impact engines that support them now, ie: DPF Systems, and EGR Diesel Engines that recirculate exhaust gas to be re-burned once again to ensure 100% fuel usage (V10 2004+, not including the many years of Jetta TDI's)?

 

[AndrieK]

It's not a loss of BTU's, it's a loss of lubricity...

Now this is where things fall apart for me.

There are two issues here; the lubricity of the DIESEL, needed for the fuel system and the lubricity of the oil, needed for the rest of the engine. VW says that, if you run LSD in a PD-engine, you need to change your oil every 7,500km. My understanding is that this is due to oil contamination caused by the increased sulphur content, which breaks down the oil, reducing its lubrication properties.

I was under the impression that the oil companies were working very hard at removing the sulphur from the diesel and replacing it with other additives that would not break down the lubrication properties of the fuel, so as to ensure the fuel system does not suffer. For this reason I never had an issue with running 50ppm in either of my TDi's.

When I was at varsity, one of my fellow post-grad students did a study in the lubricity of diesel mixtures. The study was aimed at proving the detrimental effects of mixing diesel with things like paraffin, JET-A1, petrol and water. He used 50ppm as a reference in his study and the difference between 500ppm and 50ppm was never discussed. I always assumed 50ppm would be at least the same as 500ppm...

A mate of mine's dad had one of the first 96kW 1.9TDi Audi A4's and this car had all four injectors replaced at 120,000km. Cause...? Bad fuel. He used 500ppm BUT, he's a farmer and used to fill up his TDi with the same stuff from his 2000litre tank he uses for the tractors, so who knows what else was in there.

Personally I've driven a total of almost 280,000km now with my two TDi's using ONLY 50ppm and I don't have ANY issues with the fuel systems. What's more important to me is that you use a reputable filling station with a high turnover in diesel as this would reduce the risk of contaminated fuel getting into your tank. 50ppm vs. 500ppm...? I use 50ppm because of the extended oil changes.

 

[v10treg]

Andriek, I totally agree with your point with oil contamination with 500ppm diesel. 50ppm ulsd burns cleaner, and is less 'sooty' out of the exhaust. In North America, there is no way of getting anything else but ULSD, unless a rail yard will fill you up from their stock!

I'd rather use ULSD (no choice), but with perhaps a 2% bio blend.

It's good to hear you haven't had any problems in your TDI's.

 

[siberian]

There is a BTU issue as well as lubricity. After all replacing sulfur for lubricity and emissions by carbon, affects the caloric content. This will not only make your engine run colder but also decrease the mpg you get at the end.

As to choice of 50 or 500ppm as you said V10 you ain't got a choice other than standing at then end of the well and topping it off.

[AndrieK]

Now this, again, is where we are screwed. Biodiesel is not available AT ALL here. There were talks of a pilot plant being set-up about two years ago, but I suspect it's been canned. IIRC they said they could get it into the market for around ZAR10.00 (US$1.32) a litre where we're currently paying around ZAR7.60 for 50ppm.

I think I saw somewhere your ULSD is 15ppm? Is this correct? Maybe this is what's pushing it over the edge?

So, v10treg, is this what you are running in yours? ULSD with a 2% bio mix?

 

[German]

Yes would have to agree, here at the moment they are running on a blend of peanut oil and it's playing havoc with the injectors, bio diesel from local farms but I would not put that in my touareg just yet, I think it's raep seed oil but it smells if you drive up behind, and another one been tried here is cooking oil from take aways and refining it and using with diesel this also smells terrible, I use the same station always and have not had a problem but then there are a large precentage of diesel's on the road here @ 1.05 euros at the moment

Rapeseed oil is actually canola oil. I use it for stir fries and chinese wok cooking beats anything else.

Now cooking on the Wok is something I admire about you, Siberian! Nothing beats high-heat cooking for Chinese!

 

[siberian]

Nope and the secret of rapeseed oil (which other than in Hawaii I haven't found any) which is actually known as Canola oil, was discovered by the CFO when she went to China. I asked her to find out what oil they used for their stir fry and that's what they use. My Gral. Tso recipe is (if I say so myself) perfection, my lemon chicken is not bad either as are... millions spent in R&D Main hassle is finding the ingredients of course, like Thai eggplant and keffir leaves for my green Thai curry; but I digress...

I'm no Chinese expert when it comes to their cuisine, but when I go to authentic Chinese restaurants on those rare occasions, if I recall correctly, their menus make mention of peanut oil for their high temp type of cooking. I can also distinctly taste it on some of their fried stuff. Peanut in general seems to be widely used. Maybe it depends on the region of China that the individual comes from??

 

[German]

the peanut oil was comming from holland

 

[siberian]

VWDude, as I said, millions in R&D and canola is what I swear by as well as my cast iron wok (not easy to find). But the key is the oil must be HOT and allowed to heat up every time you take chicken out of the wok, for example, and add more (coated with corn starch).

I love it! Where else would you find an informative discussion on various diesel fuels and cooking in the same thread.

 

[volkswagendude]

Where would sesame seed oil fit in all this?

 

[siberian]

Well now, sesame seeds need to be sprinkled over the dish (Gral. Tso's for example) just prior to serving. As to sesame seed OIL, that must never be used for frying. You add a hint of it just prior to serving and stir it in to get that special flavor. Thus a stir fry, once the meat and veggies and the special seasoning are cooked, 30 seconds or so prior to removing from the wok, add a dash all around of sesame seed oil. It'll transform your dish. Same for Five Spice, another spice I add for that special taste but here extreme caution must be used as it's very powerful and can ruin a dish in no time.

So Turtle, I don't think you'll find another forum where we've gone from diesel, turbos, and V8s (not the juice the vroom vroom) to epicurean exotic cooking.
