my car is alrdy 5 yrs with about 120k mileage. it's a wira se 1.5 auto.
currently the FC is pretty bad liao.
i've been monitoring the FC since day one. right now with ron95, the fc is :
RM0.21-0.22/km (city use)

on hiway it's RM0.15-0.16/km

is there anything wrong? i alrdy did a tuning recently and always change the oil frequent.
should i change the spark plugs to iridium ones? if yes, which iridium plugs is a good one, denso, bosch, ngk, etc?

i used to use that before. was quite good, but recently changed back to cheap proton ori spark plugs coz shop no stock. now thinking to get some iridium based plugs if possible.
but dunno which brand to get, denso, ngk, bosch, etc.

that's pretty gud i think. rouhgly RM0.12/km.
