The owner's manual says something like checking the oil level 10 minutes or so after shut down, so I've done that.

Last oil change was 2,000 km ago. So recently checked the level just few minutes after shut down and it was so low that it was near the lower "dot" in the dipstick.

Checked the level again few days after that and this time the car had been off for about three hours - the level wasn't low anymore and right at the upper dot in the dipstick.

So, what's the correct reading here? The one that's showing very low (checked few minutes after shut down) or the one that's showing the correct level (checked three hours after shut down)?

My understanding from owning previous, older cars is that you always check the level several hours after shut down (in fact, ideally in the morning before starting). However, since the owner's manual here says few minutes after shut down is fine, so that's a bit confusing.

If I go by the reading that's done few minutes after shut down (i.e. very low) and I end up adding a bunch of oil, wouldn't this be an overfill if I checked the level again several hours after shut down (once most of the oil has had time to drain down)?

Oil: using Amsoil 0W20 Synthetic

Vehicle: currently at only 8,200km and bought brand new a few months ago


So, is this thing already eating oil?
