BP ultimate or Shell Optimax
2006 Sti type uk -- i started filling up with ultimate and i found the car to be very fast and very loud and you could really feel the power.
But i put optimax in today and it doesnt sound as powerful . Still quick -- but everything sounds quieter with the optimax
What do u guys use??

optimax 99% of the time. If going for some good fun I put a bottle of millars octane booster in aswell. Main reason for the Millars is on one Rolling road session (on Optimax) was only getting 340 bhp before detonation. Put a bottle of millars in for my last RR session gave 362 bhp so it's worth the £3.99 a bottle in my view.

Can we use the new BP Ultimate? It has a ROn of 102

Your car needs nothing above 98 ron fuel

Check this link out
They run an impreza on all 3 fuels and they check torque and BHP. Optimax wins.

I run an import STi and it hates BP ultimate, runs great on optimax. In fact it runs so poorly on BP Ultimate that the last 3 times i have used it my check engine light has come on and it seems to run lumpy!
I wouldnt go anywhere near anything other than optimax unless it was essential to avoid running out.

If it has a sticker stipulating 98 yours must be a uk sti?

Wouldn't touch Ultimate.....in fact, after some of the comments i've heard from well respected experts on here, I think I'd rather use coal than BP 
Mine gets Optimax always!
