I have a 2015 Golf TDI w/6 sp manual, averaging 45 back and forth to work. My first TDI, love the mpg's. Finding a manual wasn't so easy.

I came out of a 2008 Mk5 GTI, I find the tranny gearing is a bit odd, big jump from 3-4, then fairly close 4-5-6. I do like its easy 1800 rpm at 70 though, this thing hits 80 or more way too easy and quietly, its very smooth and tight. Like the Mk7 so far.

I will roll over 5000 miles on my way home today.
I am averaging 42 mpg (fuelly.com calculated) for the life of the car. My 45 mile commute includes 41 miles of interstate where I typically cruise at around 75 mph.

We've had a cold (for NC) winter so I am hoping that as temps increase and we get our summer diesel my average will creep towards 50 mpg.

Yesterday's fill, calculated and Fuelly logged at 45.1 mpg, average speed of 33 mph for the tank (I use this to estimate my city/highway split). This 45.1 was my best tank since November.

The standout trip on this tank was a 120 mile trip (~80% highway) one evening when it started around 50 degrees and ended up down near 40. Computer indicated 53 mpg for that trip

Overall, the past couple weeks were a bit warmer here in MA, and the FE shot back up to where it was during the fall. I'm expecting to do really well once the average temps get back above 50.

Car now has 8,240 miles.
Averaging 44.4 MPG on combined driving.
Just computed a straight highway run of 125 miles, about 72 MPH on I 95 in southern ME. 48.2 MPG. (I was really patient on the foaming and made sure it was full)

Don't know how or why. Cumberland Farms in Epping NH has diesel for 2.55/g
The others are all at 3.05 and 3.10.
Been topping off daily like my Dad used to do in the 70's gas shortage lol

Im finding my MFI fairly accurate. Im geeting about 42-43 in the city with most trips averaging about 10-15 min. On the highway, Im getting an easy 54+ if all highway.

Are you guys getting good mpg with the DSG transmission? Debating over manual or DSG. I just can't stand the traffic in Los Angeles with a manual transmission.

There's quite a lot of discussion on this topic further back in this thread, so I'll spare everyone the recap. I'm doing pretty well around Boston, although this winter was pretty rough, so my fuelly average is not looking so great right at the moment. But on Friday it was 60 degrees and I had a 100 mile trip, mostly highway, and got 55.9 mpg, MFI indicated.

My best guess at this point is that the DSG costs about 1-2 mpg in pure highway cruise FE, but if you do a fair bit of city and traffic driving, the DSG and manual will come out about the same.

Awesome thank you. Hopefully I can get a deal tomorrow on a platinum gray metallic golf.

I picked up a base 2015 Golf TDi DSG today. Pretty excited and I ended up with a black one since it was the only one on the lot with the DSG. I like it so far pretty comfortable, smooth, and quiet. I was seeing 45+ mpg on the screen dash with cruise control set @ 65 mph. I will be going out of state next weekend so well see how she does on the highway.

Had my best tank yet. 44.8 mpg over 497 miles. Would have easily gone over 500 miles but decided to stop at my usual station.
The MID was very optimistic showing ~50.5 mpg.

Too early for numbers, but I'm seeing 30+mpg displayed, even on short in-town jaunts. The old DSG Mk6 was usually in the mid-20s on this trips.

I had a regen yesterday morning and again tonight about 75 miles apart.
And to Andy's point on the cold... The high on my inbound 25 mile ride in in hot weather was 76 (indicated) and today in freekin -9 degrees f (holy crap!) 49 MPGs. I have an advantage in he cold too because my Garage is warm so the car is 45-50 rather than freekin -9 to start.
... but I have a 2015 TDI SEL 6 speed manual.
Hey BadWolf and TurnOne, If I recall correctly, you two have among the highest FE numbers that i've seen. Out of curiosity, do you know your typical average speeds?

For reference, I do a mix of city/highway, and each tank typically sits between 30 and 35 mph on average.

I'm averaging 44-49 mpg myself. I don't go more then 75 mph on the highway with cruise control set on.

I don't pay attention to the average speed but on my 'extended period' over the last 1678 miles shows 41 mph @ 50.4 mpg.

Perfect, that's what I was curious about. I've only had one tank at 41 mph average speed, and it was close to that mpg-wise.

On my trip last weekend. Mostly freeways at 60-70 mph. Two spots of stop and go for construction. Manual calculation was 52.9 MPG. Odometer distance matches very well with GPS distance. On the freeways and keeping to the 55-70 mph range, I can see the MFI showing 50 mpg average on tank or better.

I never really pay attention to my "extended period" display but I do take a picture of every tank when I refuel. My last few tanks my speed has been 44, 46, 43, 47, 50, 46, 46 mph.....

One thing I have noticed is the displayed mpg is always 4-5mpg higher than the calculated so I don't go off just what it says.

Yes, we've seen the same thing, compared to our fuel amount pumped divided by miles driven. Our display is typically indicating 4 MPG higher than what we actually obtained, which are numbers very much like yours. We're driving rural routes, typically 50-75 miles per drive, no slow short distance drives.

Great info too, thanks. Based on your fuelly average you are doing quite well FE wise. I've been tracking my average speed on every tank too, with the assumption that average speed is a decent single number metric for the type of driving i did tank (city, highway, traffic, etc).

so thanks to you guys for giving me some reference points for average speeds for some of the "top performers", now I just have to find a way to average 45 mph in a warm weather climate, then I'd really be up there!

How broken in are you?

I'm not getting numbers that good, but I'm seeing 47-48mpg sustained at 75mph on flat highway, but obviously any sort of city driving and that dips radidly. I only have 1200 miles on it though. I know how these open up after 5k-10k, and I'm already a couple of MPG up over my old DSG Mk6.
