yeh, cars in japan and east asia etc are normally set up for higher octance fuelsIsn't an ECU on a car nowadays mapped for certain fuel?

Tried it once myself.. I mowed the lawn in half the time it took before.

I assume the people claiming 102 RON fuel will make no difference have categorical empirical evidence.

Yes, obviously. Why is it so hard to understand that on this sort of car that petrol will make little or no difference? They state in the marketing stuff that it is for highly tuned race engines.
Its like having a panel filter. You might think it makes a difference but in fact the differences will be negligable unless you've had other things fitted to the car.
Won't have a significant effect, the 197's mapped for 98, so will run best on 98/99.I have never put anything other than normal 95 ron in my car because it will make no difference atall on a 1.2 16v but 98/99 octain is suposed to be better in the Renaultsports so i presume 102 will be even better.

mine has a sticker in the cap that recommends both 95 and 98. I tried the 102 in my old 182 and deffo felt a difference.

Is your reg NG57 NEU?
£2.55 a litre at silverstone today, i had to give it a go. Half filled the tank for the journey home and got a can full in the boot for those cold evenings when i wanna go for a "drive". All i can say is, SHE PULLS. Louder, raw note and noticeable quicker. Expensive experiment but a hell of a lot of fun
+1 to myself =]I think its controlled by the Variable Advance Spark Timing system.Isn't an ECU on a car nowadays mapped for certain fuel?
The 'Knock' detection system senses the change in fuel and spark timing changes accordingly to be most effective.
Im only assuming renault has this?

thats me!
Plus it would be diluted with lower RONYou'd need to run at least a full tank through before the ECU and knock sensor advanced the timing.
So sticking half a tank in will do sod all.

That's my old car!! I bought it in Nov 07 and sold it to Steve at AllVehicles. I traded my Trophy for it. I hope you're enjoying it!
That car had been mapped for the higher octane fuel. So it would show an improvment. As said, to get any significant power out would require a remap, a pointless fuel unless you have the mapping for it.BP had a stand a Goodwood last year. (I picked up loads of free key rings & stickers etc)
They had a 911 Turbo on the rollers and two different fuel lines running into it and kept switching fuel.
I seem to recall another 50 bhp on 102. So about 10% on a big power turbo. This is a 7 octane rating from normal unleaded not just the 2-3 jump for super.
I guess if people are willing to spend hundreds on exhausts, filters and other mods spending an extra £50 on fuel before going on a trackday may give better gains for less outlay. (insurance issues etc)
I believe the stations were being located near race tracks.
anyone that buys 102 RON...are just suckers...you really are!!!
Just buy a faster f**king car...that can go 0-60mph quicker than 7seconds...stop chasing the dream of gaining 00000.00001 off of a second because of the result of individual fuels.
trying to gain incy wincy bits of BHP out of induction kits....exhausts and uber high RON fuels etc etc ... and expecting HUGE gains out of a N/A car.
Better still save your cash for a track day tuition for some advice on HOW to drive properly.
