Kung ang sabi ng label ay CI-4 class ang langis eh syempre compatible yan sa makina. Wag mo ipaghalo ang langis, drain all the old oil and changed full volume of fresh lube oil.
Regarding the 20K change oil posted above. Yes you can do that if you want to destroy or retire your engine earlier

Kidding aside, dapat 5K Km lang ang change oil if the car usage is mostly in Metro Manila regardless of car brand. The metro manila traffic condition is considered as "extreme driving condition". HTH
