My 4S has used a bit of oil (showing one segment below the top arrow) and I would like to top it up.
But when its been serviced, the oil level on the display is right at the top in the morning 'cold' reading (i.e. one segment above the top arrow). So it now has two segments 'empty', i.e requiring approx 0.4L to fill up completely or 0.2L to get back to the top arrow. Should I fill right to the top of the display, or enough to get back to the top arrow?
Supplementary question... do I need to get the exact same oil, or will the same grade suffice?
