As read from another thread discuss about engine oil, we can only know if the engine oil are indeed good by oil analysis taken from  the used engine oil, where a through details, parameters are shown.

Honda engine 110k km is considered low mileage.. my engine still virgin never open up before, 270k km and it still revvv smoothly to 8500rpm every time i got open roads

Previous owner i dunno, but the seals look stock. If tukar d usually can see the gam gasket one.
The seals i tukar is the vtec solenoid seal and camshaft seal.

mine will be hitting 300k sometime next year 

yes...

unlike Balance's 260hp
I got only 200hp, probably a lot less as almost 20 years old
no oil consumption. Castrol Edge 5W30 engine oil and expensive petrol

newer K24W requirement is 0W20 already due to tighter tolerance
but old already can move to thicker oil if start to consume oil

I reckon the problem is US service intervals are based on the 7,500-mile, that is roughly 12k km

same oil pan cannot la long run unless the car mostly all freeway. US lot of cars clock up the mileage due to heavy freeway usage.
