We have a local BP petrol station which sells the very high octain fuel 103 I think it made a big difference in my Porsche as the ECU will advance the ignition. What effect would it have if used in a 55 AMG Kompressor?
Thanks

Try it. I am sure I will be an improvement.

Post back the results.
 
All depends if the ECU can adavnce the timing to take advantage, if it cant it'll be a waste of money.
 
How much is 103 RON are we still in the £3 -£4 a litre region these days

Not sure but more than likely the answer will be yes.

Unless there is a market for it,the price will remain high.
