My VW dealer charged less for service with the required TDI Synthetic, than my Toyota dealer with cheapo dino oil.

I have kept a log of my fuel use for a total of 74K miles on my '09 TDI sedan and the computer is actually not so far off the actuals I calculate. My computer shows about 43 mpg over the last 4000 miles. I've seen numbers as high as 56 mpg on a trip to work (22 miles one way). I average about 45.5 (distance driven/gallons used) on the highway at about 70 with the AC on. The computer showed about the same.

I just wanted to thank everyone for their input on my tire decision. We do have ice and snow here in the Detroit area. It also rains a bit here, especially in the Spring and Fall. I ultimately ended up with a set of Michelin Defender XTs. Discount Tire made me a good quote so I decided to replace all 4 tires before Winter set in. Again, thank you for your time and input on my purchasing decision.

I agree. Driving MPG varies by the individual, type of driving, habits, etc. My father has a TDI sportwagen. He gets 42+ routinely. I took it on a road trip out west and with my driving habits, only got up to 39.5. However, with my 01 TDI, I routinely get between 45-50 mpg (90% highway). Needless to say, I am sold on the TDI and could not imagine buying a gasoline model ever again.

I agree. I always fill up to the neck. My record mileage, obtained last summer, was 823 miles and running on fumes in the end.

I *already* run Nokian enTires on my TDI and always add cetane-enhancer at every fillup.... perhaps that is why 50+MPG is the norm for me.

Get serious. 11 MPG? I gained about 5% MPG with the Ecopias. See a comparison at this link.

#4711 of 4751 tires & TDI mpg / drafting by elias

thanks for the reality-mpg-check data on that one, cosmo! tires are good for a couple or three TDI mpg , such as switching from summer to winter tires.
 
one factor in low-rolling-resistance tires is that the possibility that they also provide lower-friction-coefficients while braking - increasing braking distance in emergency stop. there's no fooling mother nature.
 
Another way to boost mpg more than 11mpg, try drafting a cooperative bigrig, feet off the bumper- you'll really feel the mpg savings and how it pulls your car (or motorcycle). Just as a test, I'm saying.

#4712 of 4751 Bad fuel gives me the Shudders by longo2

My 06 TDI really has a sensitive engine. On some brands of diesel the car will go into convulsions between 2000 and 2300 rpms when on cruise control.
 
 It happens when the car is going down a slope and the engine is not using fuel but then when the grade goes back up and motor now needs fuel, it does a violent shake rattle and roll for a second or 2 then it's OK until the next same combination of CC, and road conditions.
 
The only thing I have found that prevents all this drama is changing the fuel brand. I drive about 500 miles a day for 3 days in a row, so each tank is run down to less than 1/4 and then I start looking for a fill up again and hoping for a no-shudder run.
 
I have tried truck stop fill ups and all the major brands...(Shell was the last one that the TDI had big problems with) Then I will have great luck with some no-name brand from some divey place in the middle of nowhere.
 (I have always had great performance from Chevron GAS in my Honda Odyssey, but the Chevron diesel is another story...poor power, bad mpgs and lots of shudders.)
 
So far I have not met anyone behind the counters selling diesel who has ever even heard of Cetane ratings..(I do ask) much less what their pumps might have.
 
Seems some forum posters are having these issues with the new models of VW TDI's but so far nobody with a 06 except me, has mentioned it. One uninterested VW service writer said "it probably needs to come into the shop and have the cam shaft and valve followers changed" A story he probably uses to make his service dept another $2000.00 that day.
 
Not saying the car at 110,000 miles doesn't need the top end looked at, but it will run fine on certain diesel and run like crap after the next fill up from a different location. Covering 2000 miles in 3 days puts me at 4 different stations in 3 different States.
