I switched on the engine this evening, and the oil levels were about 75-80% full. I turned off after a couple of minutes, did a quick wash and checked the oils manually just to make sure...
When i turned the engine on again after 20 minutes, the oil level indicator had dropped to 20%. I remove the key several times but saw no change. Did i make any mistake?

 

Normal, cold oil was clinging to cold engine parts and had not made it back to the sump.
Best to check it when it has been sitting over night or fully warmed up, 15 minute drive, after shutting down and sitting for 10 minutes.

 

Its funny though, that the first measurement was ok, but 20 minutes later the indication was totally different.I will drive the car to the repair center and then we will check the oils there, along with the mechanic.
