What fuel are most of you using in your Stis. Noticed most petrol stations do not even sell 98. Do you mix and match when available or just use one type. Does it even matter what fuel you use.
Is there that much of a performance advantage with 98. Is it better to use 98 or 95 with octane booster.

97 RON is recommended or better still Optimax.

You can use 95 but performance is decreased and the engine less smooth.

I wouldnt put 95 in a standard Uk turbo let alone an STi. If you cant get SUL or Optimax then put that in. If you can then get some OB for 95. No use in buying horsepower then not being able to use it all . Better still optimax + OB
