Before starting Rotax aircraft engine it is advised to open the oil sump, leave the cap off and rotate the propeller by hand, with the ignition off, of course. Keep rotating until you hear a murmuring sound coming from the sump. This is a sure way to know for sure all oil is in the sump and the engine is loose. Its important to check the oil level too, which you can do after the flight , but remember that hot oil can be very nasty.
