Hi,I need your help guys cause two of my babies is due for an oil change.My APV is on its 30k KMS and the Alto on its 15k KMS,I want to do the oil change sana sa suking talyer and I was wondering what oil to use. Most of the reviews and comparison I red and watched Royal Purple tops the other,and I was thinking to use Liqui Moly Ceratec? My question is, Can I mixed them ba? Or ibang oil na pwedeng gamitin?
