I've heard of this..... average price will be £2 a litre

Expect about 2.28, it may be a co-incidence but one of the bp stations here in Milton Keynes that stocks it, is on Tickford Street (Aston Martin)!!! Sure the owners of such grand machines will not be troubled by the price.
Given current fuel prices, how can this price be realistic?
BP Ultimate 102 unleaded is a specialist fuel aimed at motor sport enthusiasts. It is made to exceptionally high quality standards, and we believe that these drivers, will welcome the chance to buy a fuel of this type.
Why can’t I just use BP Ultimate 102 instead of BP Ultimate Unleaded?
BP Ultimate 102 unleaded is recommended for vehicles with highly tuned engines. The fuel is fully compliant with the UK specification for unleaded petrol, which means it can be legally used on the road by any car. BP Ultimate 102 unleaded will not do any damage to your engine if it is not tuned but in general only cars that have been tuned will experience the full benefits of 102. BP Ultimate Unleaded (97 RON) also offers more performance and less pollution compared to ordinary fuels and is intended for all cars.
Why has BP Ultimate 102 unleaded been introduced?
BP Ultimate 102 unleaded has been developed with private motor sport enthusiasts in mind. They now have the chance to buy a fuel meeting the same high specifications used at the pinnacle of motor sport in Formula 1 and the World Rally Championship direct from forecourts. It has an octane number of 102 and burns more completely to allow highly tuned engines to perform better. It is envisaged that motor sport enthusiasts will be able to fill up with BP Ultimate 102 unleaded on their way to motor racing circuits.

This is practically racing fuel and is actually A GOOD PRICE! You can't really get unleaded higher than 104 anyway, if you want more you need to go to leaded fuel (lead is a good det* suppressant).
Their is no way a MX6's ECU will be able to make full advantage of the RON of the fuel and even if it could the engine wouldn't be able to. The people who will see advantages will be those with turbos, running nitrous or both.
The octane of the fuel is an indication of the fuel's ability to avoid detonation* which is the uncontrolled explosion of fuel ahead of the normal flame front created by the timed spark of your ignition. This happens when the temperature inside of the combustion chamber gets too hot and the fuel's auto ignition point is exceeded and 'ignites'. I say 'ignites' but it actually explodes 5 or 6 times hotter than a normal combustion with increased cylinder pressure causing serous damage.
The engine will quickly fail if this condition is allowed to continue.
So what causes the extra heat in the cylinder to cause detonation?
Well this is were the turbo thing comes in - running more boost or injecting more nitrous will do it, also tuning an NA engine by significantly increasing it's compression ratio and revving it's knackers off will increase temps.
'Knock' or 'pinging' can be heard with detonation so if on a turbo car the ECU hears knock it will retard the ignition and, if it has control, will also reduce boost pressure however the ECU will always try to give the best performance possible for the conditions. So when no knock is heard it will advance timing and boost (within it's programmed parameters) until optimum performance is reached (for the turbo setup). With 102 RON you will have a significant margin of safety and so extra performance will be experienced.
That in mind, I wouldn't expect miracles from a std KL03 engine so it would be a waste of money.
I am thinking of adding Mark 626GT to my ignore list
The KL-ZE is designed to run on 100 RON fuel as sold in Japan.. so although plenty capable of running our normal 95.. (or even lower RON in the states) it will be running with less power than optimal.. and will benefit from using as close to 100 RON as possible.. using 102 may even help performance..
A normal KL-03 / DE as used in UK cars, is tuned for 95 Ron.. 97 does help a tad, and as Mark said, 102 may be outside the scope of the ECU.. although those using Megasquirt or similar may be able to tweek a bit more from it..

Yes, I was going to mention the 100 RON fuel that washes the streets of Japan and yes the ZE can make better use of a higher RON fuel than the DE but it's really giving a safety margin rather than an out and out performance enhancer.
Megasquirt would allow you to tune further however you can only advance the ignition so far.
Petrol companies are usually quite modest about actual power gains by using their fuel because it's just one part of the power equation. The real trick is to get more air in there (OK O2).

so shoving in some tesco 99ron isnt worth it? must admit mine does seem to run better. Around town mileage is about the same but on longer fast runs, i do actually get a measurable increase in mpg
.....and so i find myself asking, 'At what point does the 'end' start?!'
