Custom GT Wing mounts

Good day to all ..

I need to know the suggested engine oil for Mivec 1.6 DOHC 4G92,
Recently me done with general service on timingbelt/water pump/spark plugs and so on..

So for the first time, i used HKS Semi Synthetic 10w 40 4liter engine oil. It suppose to run for 5000km but now its just 3500km ran and the oil stick sitting at 2nd bottom line..

Current status:
Engine PnP
Iridium Spark plugs
2" Direct piping
HKS Semi Synthetic 10w 40


The engine oil pretty good though, made...
