not really, the service book recommends changing it at 80,000 kms, i'm at 85,000km now. actually, its not that bad (40 bucks from super cheap)...;) its the labour thats expensive (100+ from toyota :o) i rang ryco and they said that the Z654[iT] can be used for both SA and JP builds... i'm not very confident about changing it for the moment after reading the manual... so i'll wait for my uncle to have free time so he can help me out
