Following on from the recent discussion about fuel quality on the corsa vxr/cupra thread. Rather than filling that thread with off topicness Ive decided to see what pepole think in a seperate thread.
When I first got my Cupra I put 95Oct in it for a while, I dabbled in the odd tank of Vpower but didnt feel much difference, though MPG did increase slightly(circa 15-25 more miles from a tank. I realise that the car need to "learn" what fuel is being used and therefore to feel a difference you should run a few tanks of the stuff through the car so It can adapt its various parameters.
I dont like paying more for less(or nothing) so using Vpower/Tesco99/BPUltimate for me was always a bit of a sore point, lol.
Anyway, I ended up having the car mapped, so its now "set up" to run better on 99Oct than 95. So I havnt had to put any 95Oct in the car yet, I got some 97 from an Esso and didnt notice much difference. I have no conclusive or otherwise evidence that says higher RON fuels are any better.
Thorney Motorsport(sponsored by Tesco btw) have done quiet a few large fuel tests, tesco usually comes out best, I think Shell Vpower came out best once or twice as well. While sponsorship of the race team *might* influence results, Im not sure the dyno's are aware of any sponsorship. They make interesting reading any way. Heres a few links.

I also read a which article that ran a few normal daily drivers on both 95 and Higher oct fuel. They concluded there was no real advantage compared to the price, but when you think about the cars they were using you can see why. Though they specifically mentioned the 1.4tsi (170ps) engine saying it took well to the higher octane fuels and Shell Vpower was the best. So our 1.4TSI's surley would like some too?

Also, Im sure this has been discussion on the forum's before but rather than cracking open a year old thread I figured a new one would be good for debate.
