z1000 Posted June 20, 2006 Posted June 20, 2006 When filling up yesterday i was wondering if i should be using octane booster ? Car is a uk Sti 8 with 300+ bhp and i generally fill up with esso superunleaded 97 ron as theres only 1 shell garage 15/20 miles in the wrong direction. Steve
craig mac Posted June 20, 2006 Posted June 20, 2006 Am running 300+ something[] and always use Optimax and Millers Octane booster, every tank Craig
st3ph3n Posted June 20, 2006 Posted June 20, 2006 If the car is mapped for 98/Optimojo then there's no need to run it with booster. Unless you're intending giving it some major beans or taking it for a visit to the track. Then you might want do add some just to ensure more protection against the dreaded det and ignition retardation. If it's mapped to run with booster then you better get some.
