so, does using the more potent stuff make much of a difference?
does i matter if one fill up you use one and the next you use the other?
so far ive only used standard fuel, mainly due to the price. things have change since this post was started! normal unleaded is well over £1/litre never mind the special stuff!!

you've done a good job churning up a load of old threads!!
If your going to use a more refined petrol, e.g BP Ultimate or Shell V-power, stick to it, you cant dibble dabble in half and half.
I changed over to 97+ ron (normally BP Ultimate) a few months back. Some say it's better for the engine, some say its a load of rubbish, personally i have noticed very very slightly smoother differences, and am more at ease with using it, rather than standard 95,

Good to see someone actually using the search function for once!Tim_GTi wrote:you've done a good job churning up a load of old threads!!
But I would agree, there is no point switching between the two.
And as for whether using the higher grade stuff makes a difference, I believe it does. Go from some cheap normal unleaded to V-Power and you can tell.

Always without fail V-power 99RON 106p
1.Power gains, not noticeable.
2. Engine runs noticeably smoother.
3. More miles per gallon.
The only way you can really extract more power from the higher octane, in a car like the GTi is to have a remap, to alter the ignition timing etc.
Only the expensive sport cars, such as the newer EVO or WRX have ECU's that adapt to the higher grade stuff automatically.

i use v-power when i shop at rainbow (my local store has a shell garage attached to it) and get a 4p off a litre voucher (i also collect the drivers club points with shell). and i use tesco premium fuel (98-99 ron) when i shop at tesco and get a 5p off a litre voucher (plus the tesco clubcard points). basically the higher the octane rating the bigger bang it makes, and that means more responsivness and more mpg (in my experience anywhere between 20 and 50 miles more per tank) and if you play smart with the vouchers and point scheemes it needent cost much more than the standard pish, and its better for your engine.
