how long did it take your GTI to loosen up and get decent MPG?

[Hully]

Its getting worse 60/40 stuck in traffic & 50-60mph runs 26MPG today  and I was taking it steady

Guess I need to get it back the stealers 

Are you running the car on V-max, other super, or normal?

[wantmygti]

50-60 mph in mine returns about 40mpg

[Peskarik]

50-60 mph in mine returns about 40mpg

really?  that is fabulous!
what is "about"? - 39 or 35.1?

[wantmygti]

Say between 39 and 41. Of course that is at a constant speed, not stop start or anything.

Sitting on the M25 at 50 helped prove this!

[skylark]

Mines around 23 MPG.
But that is a slow 7 mile crawl to work that can take anything from 15 - 45 mins.

Don't forget that the MPG improves vastly when the engine is nice and hot.

Never normally look at the MPG in mine as after the TDI I thought it best not to

However I have just been to the Lake District for 4 days and then back down and decided to Check it out for a change. Bear in mind that I have a DSG and cruise control for motorway driving and the results were derived from top up to top up and using the trip gauge for distances travelled.

I topped up with Shell V-power as I set off and zeroed the distance travelled. I topped up again three days into the holiday and logged the fuel used by the refill and as I got back home refilled again and logged the fuel used and then took the mileage for conversion back to MPG.

Result = 31.8mpg

This was a combination of over 180 miles of motorway driving at "eager" speeds and "spirited" driving around the Lake district on A and B roads including Hardknotts Pass and Wrynose Pass (I think that's how they're spelt!) of another 230 miles.

A similar incursion into the Lake District a few years ago with the MKV GTTDI (Chipped) resulted in 42 mpg

So for a car with better performance (which was definitely used ) and petrol instead of diesel it returned only 10mpg worse

Now....this is probably the last time I will make any comparison, so I don't depress myself with worse fuel figures in future :embarassed:

over the first 2-3k miles i have averaged 31.2 mpg and this has been mixed driving , lots of relaxed cruising 60mph and also upto silly speeds, red line etc etc on V Power from Shell.

the gti will not produce good mpg over short stints - my commute is 45 miles each way and this helps with mpg.

you will not get over 30 mpg on short stints , don't want to state the obvious but 200 bgp and heavy car will always struggle 

[Snoopy]

I can get low 30s out the manual GTI day to day but the DSG i regular drive too is normally 3-5 mpg down on the manual on the same routes.

[vanders]

Just over 2k in ED30 - seem to average 32'ish. Mostly daily commute on fairly open A148 at around 60-70mph - except for couple of 30mph stretches.  Few odd blasts obviously to clear out tractors/lorries and of course caravans which too many drivers seem content to sit behind.

About time we had minimum speed restrictions when driving on basically empty A roads - 50/55 mph?

[Dogbucket]

Average over the last 2k miles is 31mpg. Best on a single journey was 41.2mpg, which was largely 60mph on the M25. Getting around 370miles to a tank.

IIRC using Vpower (98ron or higher fuel) allows the engine to run longer in Fuel Stratified mode so gives better mpg compared to 95ron.
