Sorry to hijack this thread but I hope someone can share a little on oil change.

I recently bought a 2006 City VTEC with 14000km on the clock. According to the Honda manual, the oil change is to be done every 5000km. I find this interval very short, as even Proton cars come with a 10000km service interval.
I checked through the forum, and some people recommended using semi-syn oil and stretch up to 8000km. Is this advisable?

There are also talks on changing the CVT (gearbox?) oil every 20000km. Can someone elaborate more on this?

If this has been discussed before, I would appreciate if you can point me in the right direction.

I've read in several mags and sites that with full synthetic oil, you can even go up to 20,000km. Just change the oil filter every 8000km, top up some oil and you're good to go.
My colleague's Fiat Panda has a 20,000km service interval and he uses only semi-syn oil.

Not practical ler, if must change oil every 5000km

After having a closer look at the manual, it recommended changing the engine oil every 10,000km if the vehicle is under normal usage. Gear oil is recommended to change every 24 months or 40000km, whichever comes first.

I think this should already answer my question . Thanks btw
