@pwuser159749911157 According to the Workshop Manual found in the original post of this thread here, You'd need 3.7 Liters every oil change if you also change the oil filter, else you need 3.5 liters. Honda's own Engine Oil bottle is also 3.7 liters, however I use Total Quartz 5w30 Fully-Synthetic which comes in a 4 liter capacity so I pour it all in.
At Oil Change:
3.5 L (3.7 US qt, 3.1 Imp qt)
At Oil Change including Filter:
3.7 L (3.9 US qt, 3.3 Imp qt)
After Engine Overhaul:
4.5 L (4.8 US qt, 4.0 Imp qt)
But as an engine ages it might consume slightly more oil (not a lot more) which is normal.
