I have read a lot of stuff on here about (percieved) quality of fuels and those which are believed to give the best performance.

I have ran my UK turbo 2000 on BP Ultimate but since the price hike have been having a re-think. Have moved to Shell super 97 Unleaded.

I dont think we have optimax available in Ireland or tesco 99RON. What are you guys running your scoobs on?

Of the fuels you've used which offer the best performance without adding octane boosters?

TT

BP Ultimate plus Pro boost works for me

your uk sccob will run quite happily on 97 RON. if you have a jap import then 97 RON + some octane booster is in order until you invest in another ecu and remap. i just run 97 BP Ultimate, but when attend event on the mainland i would indulge in a little optimax
