How long do you have to wait to check the oil level after the ignition is turned off? So, I wait for about 15 mins to check it, and find the level 2 mm below the minimum. I'm a little bit scared, so I fill it to about 1 mm under the max. I put the car into the garage, and the next day I take a look again at the level, and suddenly it's about 3-4 cm's above the max... *-) Ow, and how much oil should there go in? is it 5 liters without the filter change and 6 including? Thanks!
