I have run my WRX on Opimax from new, 2 months and 3500 miles and she has'nt missed a beat except when i put an emergency £5 of normal in, felt like the engine was fallin out!

Go Optimax its cheaper that SUL and way cheaper that NUL + booster

Where do you get optimax ?

Have a look on the shell website - they give locations where Optimax is available and listings when Optimax will be available in other stations.

I found differences in my P1 - found SUL is best, next is Optimax and only ever use UL in emergencies....

The answer is not in Scotland, yet. I understand that it will be available all over Scotland within the next month or so.

Ross. Do not run the STi on 95 unleaded even with octane booster except in emergency. Then avoid heavy throttle applications. Stick to super + booster until Optimax available.

The new STi Type UK cars can run on 95 RON unleaded without any modification, though you will lose a bit of performance.

I probably would still only use it in an emergency though, and wouldn't push the car very hard.
