I've been using momentum for a couple of tankfulls recently and found that i got 1-2mpg better than V-Power. Only reason i was using it was due to getting up to 15p per litre off when shopping recently and i also got £15 worth of vouchers from my clubcard points. I normally use V-Power and i've just got £10 worth of vouchers back from that so will be switching back to V-Power.

My ED30 is currently on V power and I am driving like my Nan and done 307 miles so far and range says I have another 105 miles.

Last V power driving normally I saw 330 miles and on Tesco 99 its was exactly the same.

Do most people use 98ron and above? Just got my GTI and it says to run at that. But would it make much difference going for normal unleaded?

For the health of your engine especially if mapped, yes

V power makes my stereo louder but momentum make my boot open faster?

Expensive fuel though, I do a lot of motorway miles will it make a difference? Also how does it protect your engine better? Is it not just some marketing gimmick?

Hight quality (octane) fuel will burn better not leaving carbon deposits and is less
Likely to detonate early preventing damage

Running your car on 95 RON will not damage your car in any shape or form.  Using a low quality fuel might.  There are poor quality 99 RON fuels too....

The car is designed to run on 95 RON quite happily but might not make the manufacturer stated power or mpg.  The mpg difference is negligable based on my calcs on a click to click fill up.

Many many A3's and A4's with the 2.0T in them have never seen anything better than Morrisons finest 95 RON and are still ticking on.

FYI,  here's my MPG figures for the last couple of months:

 Date            Lts     Miles    Real MPG      Cost     Cost /l   
30/09/2011   39.81   319.8   36.5   £52.51   £1.319   95 RON
07/10/2011   26.14   202.7   35.3   £35.52   £1.359   99 RON
21/10/2011   38.46   291.2   34.4   £52.27   £1.359   99 RON
27/10/2011   40.25   299   33.8   £53.09   £1.319   95 RON
04/11/2011   43.05   314.5   33.2   £58.94   £1.369   99 RON
17/11/2011   44.86   343.6   34.8   £60.52   £1.349   99 RON
21/11/2011   41.78   325.5   35.4   £56.36   £1.349   99 RON
25/11/2011   33.58   251.9   34.1   £43.62   £1.299   95 RON
07/12/2011   34.71   240.8   31.5   £45.09   £1.299   95 RON
14/12/2011   43.14   319   33.6   £58.20   £1.349   99 RON

As you can see, changing from 95 to 99 RON makes little to no difference to the real MPG.

There is a noticeable difference in performance, more so when you're using the upper part of the rev range than the lower part...

Thats really useful info thanks! Where is your 99ron from? Shell is the cheapest where im at and its 1.41!

Not really bothered about the power its MPG im looking for. If there was a massive difference I would have gone for the better stuff but doesnt seem like there is...

Its from Tesco in a place just outside Aberdeen, I live out in the sticks so without making a huge detour its the only place on my commute that sells the stuff and sometimes they can go a week without it.  Hence the mixing between 95 and 99.

Certainly on my experience the difference is negligible and easily offset by driving with a heavier foot, having too much for breakfast, heated seats on etc.  I'm sure in a laboratory experiment there is a difference but my real world experience is that there isn't.
