Just been watching 5th Gear testing 95 Ron fuels V "super unleaded" from Esso,Shell,and BP in a 236BHP Golf

Until recently I have always bought on price,whether that be Branded or Supermarket, with a 50/50 split of both. For the last couple of months I have ran both my T5 and R on Shell V 98RON.

To be honest I did notice a small difference, both cars appeared to be a little quicker on the pick up, but after almost 2,000 miles in both cars I have not seen any increase in MPG, and the performance increase as blended into "the Norm"

5th Gear showed an approx 5BHP gain by using Shell V over the benchmark BP 95RON.

What if anything are other members experiences of using 98RON fuels?
5th Gears conclusions were similar to mine - Yes there is a difference but not sure if its worth the extra cost.

One tech question :- Ok the fuel allows the engine of the car to produce more power, by giving a bigger bang,BUT does the better fuel allow the engine via the electronics to alter its own parameters to produce more power giving a double benifit?? ie alters timing/fueling etc

Cheers

Bob
