    Hi Robert,

    I don't know how high your oil tank actually is, but Rotax has installation guidelines for the height of the tank in relation to the engine. If your plane Mfg mounted it out of spec that would account for the oil being siphoned out of your oil tank. If you mount tanks too high siphoning of the tank can result. This is the only type of thing that I have seen that siphons oil out.

    It's easy to 'gurgle' the oil back after flight, and if there is no oil on the hangar floor next time - it hasn't gone anywhere other than to other parts of the engine, has it ? You still have it.

    Your discretion.

    Holding against the compression for a few seconds helps, too.

    I ran into this same situation when I first started flying with a Rotax 912ULS. I was instructed by Ronnie Smith the Rotax instructor to stop on the compression stroke a few second every time I rotate the prop. By doing this I can get the engine to burp and the oil back into the tank in just a few turns of the prop. I also find it best to check the oil level after each flight. It provides a better indication of actual oil quantity and usage (which turns out to be none) between oil changes. This way you always know what the true level is even though when you burp the engine when cold it may only register mid way on the dip stick.
