it also had some guy form shell speaking on their behalf, he didnt really put up a big fight  :undecided: :huh:

because he knows how pointless it is putting V-Power into a car designed to run on 95 RON which is what the test was about

....Agreed. But the issue is the misleading and libellous statement that Super fuels are a waste of money, worded in the headline (according to the OP) to imply that it's generic and not specific.

How about someone posting a link to this written article?

If I had run my former car on 95 ron it wouldn't have been long before a piston melted, or the big ends went.  I fitted a knocklink to the car and tested using 95, and optimax as it was at the time.  Needless to say there was a hell of a lot of activity on the knocklink when the 95 was in the tank.  I also recall a test EVO magazine done comparing V-Power, BP ultimate and normal unleaded, and a GTI was one of the test cars.  I think the BP ultimate showed the highest increase in hp.  Got the mag somewhere, might dig it out for a look.

As I understand it running 95 octane, even for extended periods will not damage the engine on the Golf GTI or any car running knock-sensors.

The car is set up for 98 octane and will run at its best on that brew. If the knock sensors detect knock, the ECU will back off the timing in stages until there is no knock and then slowly advance it again until knock is detected and then the ECU will back off the timing etc.

Equally, running the Golf GTI (or almost any standard road car) on higher octanes (i.e. >98) will not be of benefit (it's unlikely to be detrimental either) because almost all of these "negative feedback" type systems will not advance the timing to take account of higher octane fuels.

My DC-2 Integras felt awesome on 98 and awful on 95 octane. My S2000 was a little more subtle but I could tell the difference. My Jag S-Type R really didn't like the weak stuff but would still run. I can't comment on my Golf as it has only ever had 97 or better...

I suppose what I'm saying is that "Super" fuels will not gain you power but using normal in these types of car will lose you some - depending on the nature of tune and the knock sensor/ECU programming it could be quite a lot...

Absolute rubbish.The RS4 is defo quicker smoother and more responsive than the odd time ive been caught short and hadto put 95 ron in.
BP ulimate also gives me betta MPG FACT.

Its only effective in performance engines IMO. A 1.6 FOCUS WTF!!! :sick:

In SA we dont get "Performance Fuels".

We get unleaded and thats that. Same price wherever you go and we have never noticed any difference in the GTi's power...

I ran my mk4 1.8T on 95 and this car on opti since that is the fuel they were set up for.

This I think is the key to the whole debate as Corgi illustrated.
