by the way.. after i pumped full tank.. i only managed to get around 270 km (combination of urban and cruise driving)... asked the mechanic to check on the air fuel ratio using dynojet wide band ...
the results was around 13.0-13.5 during idle (occasionally 14.5) then during 0.9 bar -> 11 .
any idea mates ?? anyone suffering from the same fuel consumption like mine? or is it normal for MY97 GC8 uk spec?
