If you are near greengeeker I think you should make an appointment to have it looked at. If all that extra fuel is not coming out the exhaust, it's got to be going somewhere. Only place I can think of would be past the pistons or rings and in to the crankcase.

Sounds good, I'll get in touch with him. Oil smelled good and feels/looks normal (at oil change). Just did an 10k oil change 2 weeks ago (I let it go a bit longer then i like but oh well)

Maybe somebody is stealing your fuel? ... A gallon or two here and there is not usually noticeable BUT they don't realize we are TDI folk and get worried if we have low MPGs! ... they are messing with the wrong ones ! ;-)

Maybe more likely than the above , a fuel line somewhere leaking slowly?

I would actually prefer someone to be stealing my fuel. That would be an easier fix for me (click clack;)😄). I live in the middle of nowhere, and so that's not the problem. I take long enough drives i can see the gauge go down....

I looked for leaks and there are none to be found from it sitting, as well as the other day I let it sit and run for 10-15 min and there weren't any wet spots under the car after. Its also a sealed system so a bad leak would cause noticeable problems. I really am curious as to what it could be.
thank you for the ideas!

I have a Rocket Chip Stage 2 tune with extra extra large fuel injection Nozzles, and driving around town in KC I can pull 42 MPG pretty easily - an all highway trip should get me 45+ MPG and >600 miles for the tank (I've actually pulled 735 miles for one tank - put darned close to 17 gallons in it !). O1m changed out to 5 speed manual at 252,000 miles (currently at 378,000 miles), and I can spin the tires in 1st and 2nd gears. I usually drive pretty sanely, and I can pull redline+ RPMs in at least 2nd (and probably 3rd and maybe 4th gears as well - I haven't taken it that fast).

Oh - I do have a ScanGuage 2 and on the guages - I use Avg MPG, Boost, water Temp (to makeup for lack of guage / idiot light) and MPH. If you coast downhill in gear, it's very easy to get to 50 MPG.
