hey, im just wondering how big is our sump and how much oil should i put back in after i drain it all? thanx adam

Not sure, however if your in a hurry just put in about 4L, wait a few mins, then check the dip stick, wait a few more mins then check it again.

Just add a little bit of oil each time (500mL/1L) untill it's at the desired level, it should be okay if you go a little bit over the full mark, but not to far...

4.7L per service manual including oil filter, however as stated above check as you go.

Dont forget to apply a small amount of engine oil to the o ring of the oil filter.
