not know about spectra FC
but own a blacktop before...FC depend on your right foot
if you drive 80-90 only, rev under 4k rpm, the fuel consumption is astonishing..
i manage to go back to kota bharu kelantan from gombak for only rm50 petrol(petrol is around rm1.80/l)
but i rarely exceed 90kmh that time
however, if you manage to stick the accelerator pedal to the floor all the way, your fuel warning will light up when you approaching gua musang..also before this, i fill full tank at gombak, go to puchong at normal speed and from puchong i floor all the way to ipoh while tailgating 325 coupe on plus highway, the fuel is almost empty at tapah rnr..so basically, it really depend on your right foot at all..
for the maintenance, just need to maintain engine oil..need to choose the correct engine oil or else you'll find that the engine oil disappear from your engine..and for the parts, reliability etc, dont worry..it really tough engine..(at least on my case)..never brake down..just once the clutch broke up because i always slam it when changing gear..
but 1 thing you need to bear in mind..this engine is designed to run on RON100.so, it is advisable to use RON 97 since ron 100 is not available in malaysia..even using ron97 also sometimes cause knocking..even worse if using ron95..lot of power lost can be felt if using ron95..
