I use ESSO 98 ron only because that was what it has been set up on, there are so many out there now, there is a Tesco near me ( i use the 99 ron in my other cars ) but i want to try the BP Ultimate if i ever get the gear box sorted !!

( is BP the one they recon approx 7% increase in power / torque ?? 450 bhp + 7% = 481 ??? hmm time to test that me thinks !! )
