Oh I did not know about Honda city club thread but now I will definately go through this thread.
Service manual could not be downloaded from the link. May be it has been removed from the link.
It is mentioned in Maintenance section of this thread that Oil capacity is 3.7 ltr. I poured 4 ltr. So should I drain 0.3ltr or 1.5 ltr? how much because of 20w50?
Is my decision of using 20w50 is correct? If correct then 20w50 should also be in same quantity i.e. 3.7ltr?
