      I just drove from New York City to Asheville in North Carolina. At 72mph, the mpg peaked at 37mpg, but 90% of the time, hovered at 36.7mpg. According to my last fuelly fill up, I did 34.3mpg, which included my stops and some hill climbs coming across the Appalachians.

      That's a 2.5l with 5,000 miles on the clock. Tyres are at35psi cold.

      With the old 5th gear avg is around 29-30

      The TDI 5th gear .717 verified at the pump, it was 33.5 mpg (all highway) and torque called it between 35-36 mpg. It was a warm day 86F (30C)

      I am pleasantly surprised with the TDI 5th

      How difficult was the 5th gear swap?

      07 2.5L 5 speed manual 90k miles, BSH CIA. With my wife shooting around town, last tank averaged 21mpg on 87 octane. Filled up with 93 octane then drove 180 hwy miles @ 90mph and averaged 28.3mpg.
      I'd say the higher octane helped. Only issue is at idle the engine ticks way louder than before.

      I was lucky and I had the diff and 5th gear installed.

      A) I was definitely not going to install the diff myself. I have a friend who is very experienced and he says it sucks, especially if you don't have the tools or you haven't done it before.

      B) 5th gear swap isn't bad if you know what you are doing... there are a lot of small pieces and clips that are important and I didn't want to deal with that. From what i've heard the install isn't long if you take it to a shop which knows VW and their transmission... ~250 for the gear set (set two gears are needed the link below explains) and about $100-$200 for installation Look here:

      This site it awesome, a tonne of good info: http://www.myturbodiesel.com/1000q/m...ar-swap-VW.htm

      Here is a written on: http://www.myturbodiesel.com/forum/f...r-install-868/

      I knew the 020 transmissions were easy to put a TDI 5th gear into. You could do it with the transmission in the car in your driveway; I was curious if it was just as easy.

      You are very correct and I believe that is what the diy shows.

      Filled up with some Shell 93 today. Last tank was under 23mpg on some sh!tty gas station that I usually avoid like the plague. Paid $5.60/gallon

      Tank is not looking so good with 93.. Im not driving her remotely hard and I have only got 170km to my first 1/4 tank.

      How are you guys not getting a least 33 highway? As soon as I hit 70 - 75mph, hit cruise, I get 34 - 36 easily over anything more than a 10 mile stretch. The only way I can think of getting it below 30mpg would be to hammer the throttle and slam on the breaks continuously. Mind you, I see plenty of people driving like that

      Says the man with the 2011 motor...

      The fuel estimations have changed since the onset of this platform (2005) till now. I think for my 06, the fuel economy was said to be 22/30.

      But the EPA made the mileage estimates more stingy? I didn't realize there was such a diffence in the last few years, especially given the engine size is the same and gets an extra 20hp thrown in.

      Yeah, just found that in your other thread. I'm not exactly sure, but at about 70 I'm barely hitting 2200.

      Get a UM flash that actually optimizes the use of 93. I did many tests with my car, stock software, and 87 did as good, if not better, than 93. Now, thats not the case with the UM software.

      Good Catch! For some reason 93 was sticking in my mind. Looked at receipt, says 91. Dunno why I was thinking 93...

      Is this the MFD reading out 33mpg or are you using torque? torque is about 8%-10% higher then actaul

      The MFI more or less matches what I put into Fuelly.

      Today I drove back from Virginia to NYC - got 38mpg for the first half of my trip, and 36.9 for the 2nd half.

      OK, here's ,y last trip. The cruise is set to 77mph (last one is 72 though) and you can see over an hour that the MPG goes up from 34.1 (pic is a little blurry) to virtually 38mpg.

      The last pic shows my range as 465 miles, with a quarter of a tank already gone, although the speed is down to 68mph, as I was in a slower zone.

      if it's all highway, I can get around 380 per tank...before the TDI 5th. It will be interesting to see what I can do with the new gear. I'll try it next time i go home (summer sometime)

      My numbers are close to Zoo's.
      Cruising at hwy speed (65) I got up to 38.4 mpgs.
      Hopping onto the interstate (75mph +) dropped the average to 37mpgs for a 250 mile trip
      (up & over the Smoky's)
