At 9000 miles (14400 km) total mileage best tank is 624 miles on 10 gallons (1005 km on 45.63 L).
Trip computer shows slightly over calculated mpg, 64 mpg (4.4 L/100km) vs calculated 62 mpg (4.54 L/100km).

Best trip on got me a calculated 76 mpg (3.7 L/100km) over a distance of 53 miles (85 km).

Now that I have tested driving in eco mode I can revert to my more normal driving which gets me more like 50 mpg (5.6 L/100km)

Car in eco mode, AC and everything else on as usual but no using the cruise control.

Does eco get you more MPG? I've never tried it as others on here claim it gave them less.

1. ECO cuts engine responsiveness and 2. As soon as you take your foot off the throttle, still in gear, the revs drop to minimum, even at speed giving a 'coasting' effect. If the 'instant' MPG is selected you can see this effect as the figure will jump instantly. Contrast this with D and S where the engine revs will still be commensurate with road speed. 3. Cornering lights are cancelled in ECO as well. 4. If is in ACC Cruise Control, it takes a lot longer for the engine to regain the previous speed after an interruption whereas in S the regain is almost instant. This does help slightly with MPG but is it worth it strangling a high performance Golf to save pennies?

HTH but it's all in the manual...

Eco can give you more mpg if you are prepared to drive like a nun, but more often than not it just frustrates and you end up putting your foot down harder.

Just collected my GTD yesterday, so will be chipping in with my calculations as the mileage goes up. During the week (on company time!) I'm hoping for above 50mpg - this will allow me to have more fun at the weekend!

First tank out of the way. Brim to brim calculated mpg of 48. Mixture of driving, ACC used temporarily, Air con used constantly.

Fairly happy with the result, I'm just hoping it improves slightly as the engine mileage increases and the initial new car feeling goes away!

It will improve. On Thursday last week made a trip to Aberdeen, prevailing temperature of mid 20s C, very hot and sticky. Climate Control on constantly, set at 17ºC after being at LOW for initial 15 miles to get comfortable inside, ACC on constantly.
Round trip of 278 miles averaging 58.7 MPG, in Sport constantly...DSG and engine. Not bad.
Last October I toiled to get above 48 MPG!

That's because it was October. With modern tolerances you'll not see many running in gains beyond 1000 miles, the gains being seen right now are down to heat and humidity giving more expansion for less fuel under combustion. Motorway speeds mean very efficient aircon - so much air hitting the aircon radiator to remove compressor generated heat and the system has to work much less than trying to get the same effect at 40mph.

First long run today, Chesterfield to Lockerbie, just under 200 miles ACC 99.9% of the journey, 49.9mpg by the computer.

Only had 675 miles on it when I set off and previous to today only been running around locally.
Peaked at 52mpg (probably due to the 50 zone on the M1) had it in Individual with all set at Normal except for ACC which was set to Sport.

Long term, after 788 miles, is 42.8mpg and it hasn't been out of Sport until today, bit of a drop from mid-high 50's in the Passat I've just got rid of..  good job I don't pay for it :whistle:

Stop hoping, unless you drive very carefully (and slow).. and the fun never stops, even when you are on company time :laugh:
