4ja1 engine older model. more power to all...TIA
know what oil your ride has in it. when using mineral oil, it is 5000 km or 3 months, whichever comes first. in fully synthetic oil, it is 10000 km or 6 months, whichever comes first.

now, car manuals always recommend to follow whichever comes first. i personally follow the distance (kilometers) rather than time (months) when changing oil.
