The Golf wagon with 6 speed usually gets (calculated) mid 40's around town and high 40's low 50's on road trips.

Recently got a stage 0.5 tune and some exhaust work.
Best tank so far on the highway at 65-70 mph is 59.3 mpg. I didn't quite believe it, started the car and and double checked the tank was full to the brim, it was.
Around town mileage is now low 50's.
Looking forward to some more fill-ups to confirm the above numbers

Looking at these numbers (length of ownership, miles, daily commute, fill ups, etc.) I wish the Fuelly app had the ability to display overall speed. Yes, it would not be easy and would require a lot more logging. Likely too much work, but seeing some of the numbers and Fuellys in signatures, it looks like there is a fair amount of TDIClub members stuck in traffic - when compared to their overall commute distance and FE reports.

with my most recent post, i was certainly not stuck in traffic :)

slow speeds (45-60 on US1 to key west) and warm temps were friendly!

I always try to out my information from the MFD in the comments on Fuelly. There is definitely a correlation in average speed and the MPG for the tank. I usually try to take the least congested route but sometimes still get caught. I’ve also noticed a difference when it is hot and I’m running the ac more the efficiency goes down.

First road trip to Montana with 2015 golf 6m with 36k . Car was a pleasure to drive and Once again I am impressed . Maybe the outa state fuel is better ? . 2 kids the wife and loaded to the roof with camping gear Averaged 50mpg hand calculating over 3400 miles( MFD showed 54mpg ) Best tank 52, worst was 46.
Car would do hand calculated 50 mpg @ 75. 46-47 mpg @ 80. This is 4000ft + elevation with 70+ temps. FYI my normal foothill driving average is about 43 mpg.

My wife has a '13 DSG beetle and a kinda rotten commute sometimes, so I had predicted upper 30's when we picked it up two months ago. So far it has been spot on. I got a 40 MPG tank by taking a ~300 mile road trip in the middle of it. That was as fast as traffic would bear :)
She never strayed far from ~44 MPG with the manual MkIV beetle for several years on that same commute. She has a couple of kinds of arthritis, so the shifting was getting old.
She couldn't be more pleased with the new car.

Bought GSW 6sp with 12k. Just finished my first tank:
80%/20% hwy/city
portions of my 80mi roundtrip commute have some traffic. Some hills (bay area), 60-95 degrees, cruise 65-75mph.
575mi
46.9 MPG
Based on the MFD i was hoping for 50, but i think i can achieve that with less city and less traffic.
Car is stock.

I've put 26k miles on my DSG since new. 80% 80mph freeway and 20% city. My hand calculated average is right at 40mpg. The cold winter weather and altitude probably knocked about 3-5 mpg off of the average but I'm not complaining. I did get one tank where I averaged 53 mpg but that was mostly 55 mph highways and 30 mph towns at sea level and 70 degree temps..

It really depends on where you live. I've been stopped for speeding at 60 mph in rural Eastern Shore Maryland. Delmarva cops don't play.
i guess we just don't cover that many miles over rural roads, its all highway for us with cruise set at 70-75.

47.9 Mpg @ 136k

Average 47.9 mpg over 237 fill ups, 136269 miles
All pump measured on Fuelly

Winter drops to 44mpg due to the cold and fuel
Interstate runs at 75-80 mph drops it to 43mpg also
Phase 2 fix dropped mileage by about 0.7 mpg

Running well
Some fixes so far:
Water pump leaking and timing belt at 85k
Sensor on AdBlue tank did not recognize fill at 125k (exciting as it happened on vacation - needed to keep the car running until we got home)

Whoa - fill us in on that last one; did you literally "keep the car running" day and night?
What was the fix for it? I would've thought that letting the car sit overnight would allow it to reset; or at most, unplug the battery for a couple minutes (?).

Not as bad as that.

Happened on the second last day of vacation the warning came up that only 200 miles till car will not start - no warning before that. Filled the AdBlue tank and still got the same warning. So the next day drove the last 950 miles back home in one go - fuelling with the car running. Hoping that I did not stall anywhere.
Drove it to the dealership, parked it and as the warning said, it did not start again.
Faulty sensor in the AdBlue tank - covered by the TDI fix warranty.
