Timing belt replacement

[Galactus]

usually 80,000km ang recommended change ng timing belt because ang category ng metro manila po eh "severe" driving conditons..

Eh? First time kong narinig ito...the parameters for "severe" driving conditions are listed in the manual (if you race it, hooked with a trailer, like a taxi, etc), not based on a geographical area. But, of course, you could have said it with pun intended...
