What Juice are you using?
Been using 97 but was thinking about trying the optimax. Is there much diff between the two. There is certainly a considerable diff between 95 and 97 - (dad filled my Cup up with 95 the other day by misstake)!
Mate with a Scoob WRX (old style), tried the optimax a few moths back and it didnt agree with the car. Was mega pinkin - so he now sticks with 97.
