Up until recently I used v_power and was getting about 28 mph on a 25 mile round trip to work. Recently due to finances I've been using regular 95 octave fuel and managed about 30 mph on the same trip. Recently covered about 400 miles in two trips on regular and managed to get it up to about 35 but know matter how smooth and fuel conscious I was it never got wany higher. Eventually I got bored and ended up with about 30 mph overall. How people get into the forties ill never know (lots of coasting) !

it doesn't matter if you coast it only records your mpg when its got a figure on the screen, if its --- it doesnt effect your average!

Its a common misconception that coasting (slipping it into neutral) saves petrol. When in neutral, the engine is obviously disconnected from the wheels (simplified), so fuel is used to maintain tickover, whereas when a gear is engaged the flywheel/crank/associated components are being turned by the wheels.
Cant quote the mk5, but the injectors are completely closed at 0 throttle when the revs are over 1700rpm on my mk2 (EFI).

Im sure this has probably been repeated a million times so sorry as im still new to the forum!  :smiley:

^^^ Ed, '---' is live consumption, if you kept it in the average calc screen the mpg would probably increase.

Re coasting... Proper Coasting is no throttle IN GEAR. Neutral uses fuel to keep idling, so run down the gearbox in gear to maximise mpg...

In terms of economy, I'm pleased if I get into the 30's.

My All-time high is 41.7 on a motorway, how people can achieve over 50 I don't know, but to be honest, how can you be having any GTi-esque fun whilst trying to achieve 50+ mpg..?

i have tested it, several times (im rather sad) and "---" doesn't change the average from what i saw

After a few long runs this weekend ive done 274miles with just under half a tank remaining. The computer says 225 miles left.

I have been driving like a big girl in a 1.6 though.

Strangely the mpg figure didnt average as high as it has in the past, only 41- dont really understand why.

Forget what the trips telling you and work it out from the next time you fill up. A 383 mile round trip and the computer said 37. 6 mpg...after filling up and calculated it worked out to be 35.3 mpg. Admittedly not too far off but off still the same.

How many litres does the tank hold anyway...thought it was 55 but my light came on and it took 49 litres to fill.

50 mpg from a gti not a chance :rolleye:

Mmm, I average 29mpg on an 8mile each way commute in town traffic.  Not too bad.  Ive only owned the car since its been cold so Im glad it should get slightly better.  I drove the length of thr country in December with -14deg showing and it was 400miles to a tank. 

On this has anyone seen an increase or decrease after the car was remapped?  I suspect slightly less.

Have heard that Revo 2/2+ can increase fuel consumption, but not sure how much by.

I'm Stage 2+ and if I have cruise control on, sitting on the motorways I can see in the 40's. Best I have seen was mid 40's when going round the M25 (SPECS 50 zone) - recorded over an 80 mile journey. My daily commute to work is 30 miles and I see 30mpg and that's enjoying msyelf.

My best has been 33mpg on a recent 90 mile journey staying in D-mode the whole time and revs no more than about 3,200 < Very boring quite frankly. Otherwise I usually see about 28, sometimes 26, and less if in Europe without such speed restrictions. I never ever use cruise control - I hate it! I'm Revo2 and don't believe what's said about improved fuel consumption on the 2.0T FSI engine.

EDD the "---" definitely registers on the consumption, and I see my 1 and 2 computer figures increase when it shows.  What the computer is showing is the value is too small to be calculated it will still register the distance travelled with a close to zero fuel usage.

If what you said were true sitting in traffic with the engine running with "---" displayed on the instant consumption would also not be registered and I'm sure we can all agree that the average consumption drops with the engine running when stationery. :sick:
