Average MPG - Longterm - GTI

[REEVE888]

I got 39 driving 20 miles to work the other day but I was driving like a wimp just to see what I could get. The next day I got 36. Both pretty good. Saw no difference between the Eco mode and normal mode. That just seems to switch the air con off quicker.

Completely down to how you drive the car is my assessment. Oh and I averaged 40 on a motorway drive from Leeds to Milton Keynes the other week. ACC all the way!!

The engines are amazingly tight when new! I didn't get over 34mpg until I'd done over 500 miles. Now that it's over 1,200miles it's completely different - the engine is smoother, freer revving and much more economical. Now I can easily get 36mpg on a longer run, even with plenty of overtaking / higher speeds. Best is 40mpg and worst is 27mpg, with a long term average of 32 mpg (since new) and climbing steadily .....

Update - milage now just over 1000, and managed 39mpg without thinking about it too much, so what 1984 is saying here (and what plenty of others seem to be saying) is true - it really does loosen up nicely...

Good to hear! 

Mind you, our resident Eco master, AP69; will probably be along in a minute to make me look like my right foot is made of depleted uranium .......

First proper run with the tuning box on today. Usually driving at the speeds i was doing i would expect around 44mpg. With the box fitted i achieved 45mpg. I know there may be some discrepancies between the MFD mpg and actual mpg but i will leave that test for another time.

I will try and break my record of 51mpg at some point, but that isn't what performance tuning boxes are made for right?!

48.5 on the way on home last night. 22 mile trip with mostly motorway. Kept it to about 65-70 on motorways and used Eco mode to its fullest - coasting. No sharp acceleration from standing start. 6100 on the clock and the engine is getting far better on economy

I think that is the best DSG MPG i have seen so far Raymondo!

Jeez - how do you guys do it? The best I've seen was 40mpg (admittedly my car has only done 1,400 miles) - but I was having to drive so gently and it was so boring that I vowed not to do it again.

So I'm just enjoying the mid range lunge and the diff juggling the power as I smear my Contis across the tarmac on the way out of roundabouts with my foot in the carpet!

I've been massively disappointed with the mpg, but am seeing some glimmer of hope. The DSG GTI I had was only managing 30mpg at best around town (2000 miles on the clock), where as the replacement Manual GTI (identical cars apart from this) is seeing 33-35mpg on similar town runs. The Manual is quoted as having better mpg which I assume is largely down to the reduced weight, but the difference is there, plus the Manual is brand new, now with 100 miles on the clock, so presumably they improve as they wear in.

So, weight and less electronics resulting in better mpg, or am I just a more efficient gear changer than the computer

Just stuck 48 litres in today and had 290 miles since last refill showing.
And I don't even drive fast! Hardly any town work, nearly all early-morning (no traffic) dual carriageway work.
I must need driving lessons. Even my thirsty mk5 did better than that!

Guys, they do loosen up. That 48.5 run would have yielded 40-42 with 2-3k on the clock.

I do think the whole "loosening up" thing is debateable on a modern engine with far finer manufacturing tolerances than we saw 10 years ago. I've never seen appreciable gains in 6 brand new VWs from 2k-30k miles, although I do see seasonal variance. I see a little loosening up in the first 1k miles and then nothing after that which I would attribute to loosening up.

MPG will be 10% better in the summer than the winter. Buy your car in the latter 1/3 of 2013, run it through winter and see poor mpg and then all of a sudden the mpg goes up considerably very recently. Is it the miracle of running in, or is it the warmer weather than makes you car take 1/3 less time to warm up and the humidity in the air that gives more expansion per combustion? Car all of a sudden gets better mpg at around 12-15k miles? Could it be perhaps those new tyres you had put on your fronts that have a far better rolling resistance than some of the obsolete OEM crap that VW uses?

Even this year on my GTD, I have seen the mpg increase appreciably for a few weeks when it stared to warm up and then dip right back down when we had a cold snap for a few weeks. My dad is at 18k miles in his GTD DSG, which he got on July 1st 2013. His mpg is no better than it was when he bought it. He has seen his mpg dip a bit in the winter and then go up a bit again more recently. He's due some new front tyres shortly - it'll be interesting to see if he sees any gains when he puts some Michelin Pilot Sport 3s on.
