Do you mean the car said 47mpg but your actual fuel usage calculation based on delivered volume was 44.3?

Doesn't surprise me to be honest, especially if you have had a few cold morning commutes. Starting from sub ten degrees and you will see fuel usage increase.

Equally, my trip home last night gave me 57.6mpg - a new home commute record for me :) It was 13.5 Celsius and the journey was about 40 miles.

Enjoy it while we can though, the super nasty winter sludge is coming... 6 months of poor economy.

Yes the car said 47.I zeroed the speedo when i filled up first time.Then after 435 miles i filled up (took about 45 ltrs).I've been running it in gently as per the handbook so i can only imagine how lower it will go once i start going faster.The 44 was with a mix of heavy traffic,A and B roads,dual carraigeways.Daily round trip of about 34 miles.
I presume the fuel economy might get a bit better once it's got a few miles under it's belt.
I know that manufacturers are economical with the truth about real world mpg.But 44mpg is really just criminal.
I'm going to run a fuel log for at least a year.See how the weather/seasons and mileage changes the mpg.Might even use the eco button if i get really desperate. :grin:

The mpg does increase when its loosened up a bit, maybe as much as 25%.

Remember whilst temperature, speed and all sorts make up your fuel usage, the variable we all can't describe when talking about this is the terrain over which we drive.

Any Dutch drivers will be creaming us all :)

If you're expecting that to happen, you'll be disappointed. You get appreciable gains in output around 640 miles (approximately 1000km), there must be some kind of "running in" mode limiting output - i've experienced it in my 2011 Scirocco 170TDI, my 2013 MK7 GTD, my 2015 Golf R and my wife's 2015 Audi A1 1.6TDI. Had 7 VW TDIs from new and never seen appreciable gains in mpg, not 5%, let alone 25%.

I'm sure some confuse the summer gains (can be as much as 10% when we get some warm and moist air in the TDI's lungs) for "running in" gains and then see their gain disappear again when winter comes around next time. Or they're trying harder to get that mpg by driving like a nun and proclaiming they have found those extra mpg from running in.

My overall MPG in my GTD is only 41.4mpg!
I can get over 50mpg on the motorway, but that's usually only about once a week, most of the time I'm just commuting to work which is only 2 miles lol

fuelly.com is good for recording the fuel used.

I had a look at that site.But it was a bit too American for me.I had a look at the Honest John site 'real mpg' for GTD's.Seems 47mpg (average) is the norm.He also recommends BP Ultimate for diesels.Might give that a try sometime.

I love the car though.You can tell there's a lot of thought been put into the engineering,gadgets and build quality.So i'm not going to become fixated on the mpg.It is my tartan trimmed tank!.

Filled up with Esso Super Diesel today, been using standard diesel from Tesco previously. It might be in my head but the car seems to be far smoother already. Costs 115.9 per litre v standard diesel at 106.9 but I want to see if it has an effect on mpg. I was am sitting at 46mpg after 2700 miles.

Filled up again this morning, 0 miles left in the tank according to the computer. couldnt get anymore than 49 litres in the tank.

Managed to get 420 miles with the Super Diesel but temperatures have been down quite a bit.

The 0 miles to go indicator must come on with over a litre of fuel left. You need to drive it more if you want to get 50 litres in.
The most I've had in mine so far is 51.531 litres according to fuelly

Bloody hell P3asa, you must be "enjoying" your GTD to only average 35mpg :-)

I'm averaging 48mpg over 20,000
