which fuel is best 4 star or optimax/super unleaded???
cos in the book it says use 4 star but everyone i know tells me to use optimax/super unleaded.

 

I run mine on optimax but super unleaded is ok if your stuck. But don't run it on normal unleaded coz it'll start pinking.

 

s1 or s2 ? if its a s2 then optimax is best if its a s1 u best check if its had hardened seat valves fitted if it has then use optimax if it hasnt then optimax should be ok but it might do some damage over a long period of time

hope this helps kev
