      Actually, the more air the motor consumes. Unless you're driving a diesel, the skinny pedal controls airflow, not fuel flow. That's what O2 sensors and MAF's are for.

      ...I bought four Humho 4x all season tires and had the dealer install them. The dealer asked if I wanted an alignment and I declined thinking it seemed ludicrous a new car would need an alignment. To be honest I was shocked I needed new tires already, but I did have a few backroad blasts that may have contributed to that...
      Pardon my newbiness (first post on VWV) but isn't it possible that a misalignment could be responsible for a sudden and noticeable decrease in mileage and a need for new shoes?
      A "few backroad blasts" could conceiveably have done the deed, and you've been paying the price since...

      Well if you're gonna get technical and bring sensors into play, the skinny pedal on the right has a sensor which sends a signal to the Throttle Position Sensor at the Throttle Body which then tells the electronically controlled Throttle Body at what percentage of open/closed its supposed to be in, that percentage will determine your actual air intake flow at the TB.

      My last two tanks were 26.2 and 26.3



      If you do any measure of city driving, you're not going to get 30. I'd suggest you start keeping track on Fuelly (or similar) and see what you're really getting. I think, frankly, that where I am is pretty average.

      Take a look at this:

      There could be something wrong with the car, but it could also be the environment and driving style. I generally drive like a granny, until someone pisses me off. I hypermile. I put just enough pressure on the excellerator to increase speed, and the slushbox upshifts between 1800 and 2000 (depending on the gear).

      These are my last 5 tank averages.
      miles \ gal \ mpg
      418 \ 14.549 \ 28.73049694
      414.6 \ 13.853 \ 29.92853534
      407.5 \ 13.844 \ 29.43513435
      417 \ 13.459 \ 30.98298536
      441.2 \ 14.213 \ 31.0420038

      The low one included a couple of spirited drives down 9 mile road. The most recent includes an "Italian Tuneup". It will be interesting to see if I can maintain the higher average.

      On my "Italian Tuneup" I used manual mode 1st gear with moderate excelleration until redline, second to 45 MPH (the speedlimit) and then bumped up to 6th gear as fast as tiptronics would allow.

      As previously mentioned, if you're doing the 30k service soon, I'd have them replace the air filter. 60k mile rec'd filter change is way too many miles, IMO. Your tires/air pressure will greatly influence your mileage. Trade-offs.

      I get about 24-28 mpg in the city. Maybe I drive like a bitch.
      i usually get 31-33 highway and 26-28 city, check valves, plugs, dirty air filter, or look for a gas station thats ethonol free, and makes sure the car is fed a diet of 93
